Hotfix 35.5.7 (2024-04-17)

Line of Sight (LoS) Changes & Fixes

As mentioned in our last Hotfix 35.5.6, the team continues to address and assess player reports of further LoS issues. While the quality and consistency of LoS checks has improved significantly, we're still not 100% satisfied and sometimes the results are still unpredictable. The team is investigating LoS checks at large occasionally having odd interactions with terrain, enemies, etc. which is causing inconsistencies in the checks. We are looking to have this resolved in the next Cert update (more info on what that means here).

For today, we have made LoS improvements to the following Warframe abilities:

• Hydroid’s Plunder (Rendered Check)
  • In addition to rendered checking, it is also no longer FOV dependent to prevent issues where low FOV settings would cause Hydroid’s body to obstruct LoS.

Update 35.5 (2024-03-27)

• Fixed bug where Hydroid’s Passive Corrosive mark on enemies would not show up for other players.
• Fixed Hydroid’s Passive causing other Armor stripping abilities to not work.

Hotfix 35.0.4 (2023-12-20)

• Fixed Hydroid’s Tentacle Swarm throwing Murmur enemies into the air instead of grabbing them.

Update 35.0 (2023-12-13)

• Fixed armor stripped by Hildryn’s Pillage sometimes regenerating on enemies affected by Hydroid’s Passive.
  • We are aware of other issues related to Hydroid’s Passive and armor strip, but those require a Code Fix that did not make it in time for this update.
• Fixed a script error caused by Hydroid's Tentacle Swarm.
• Fixed a script error caused by Hydroid’s on-hover Ability information.

Hotfix 34.0.8 (2023-11-09)

• Fixed Hydroid’s tentacles (at its max amount of 20) not seeking out new enemies to grab after killing enemies already in their grasp.
• Fixed a script error caused by Hydroid’s Tentacle Swarm.

Hotfix 34.0.6 (2023-10-30)

• Replaced an outdated Hydroid ability tip with a new one for Plunder: “Casting Plunder removes any Corrosive Status Effects currently affecting enemies, permanently reducing their maximum Armor based on the Corrosive Status removed.”

Hotfix 34.0.4 (2023-10-24)

• Added the video preview of Hydroid's new "Plunder" ability in his Ability screen.
• Fixed Hydroid’s Tentacle Swarm Kraken despawning before the ability has expired. A pirate needs his trusted companion to stick around to take care of these landlubbers!
• Fixed a script error from enemies being ragdolled by Hydroid’s Tentacle Swarm.

Hotfix 34.0.2 (2023-10-19)

Update 34.0 (2023-10-18)

Base vs Final Stats in Modding - Health / Energy / Shield / Armor Stat Overhaul

If you’ve spent any time invested in the deeper nuances of Modding, you may be familiar with “Warframe Math” - math that upon first glance doesn’t really make sense, but once you learn the inner workings of the game, it all comes together. While we can appreciate the value that complex systems offer to a certain subsect of players, there are other aspects of the game that should have clear and understandable outcomes. Namely: Shield, Health, Energy, and Armor Modding.

Pop quiz: what is 300 + 440%? If you answered 740, you may just be an Excalibur player.

Vitality (+440% Heath), Redirection (+440% Shields), Flow (+150% Energy), and Steel Fiber (+110% Armor) come with large modifier values that don’t seem to match their outcome in-game. This is because these Mods apply their multiplier to the base stats of the Warframe - i.e., the stats you have at Rank 0. In the Excalibur example, a Rank 30 Excalibur’s Health stat of 300 earns an additional 440 Health from max rank Vitality (+440% Heath) since it applies to his base rank Health stat of 100, resulting in 740 total health.

In this update, we have removed this obfuscation by having Health, Shield, Energy, and Armor Mods apply to the stats of Warframes at their current rank. Continuing our Excalibur example, instead of Vitality always applying to Excalibur’s base rank 100 Health, it would apply to his Health stat based on his rank - namely, the stat you can actually see in your Arsenal. If your Excalibur were Rank 30, his Health stat would be 300, which means Vitality’s multiplier would be calculated off of 300.

With previous Health and Mod values, additional adjustments are needed to make this revision work while maintaining game balance. By only changing where the multiplier applies, a Rank 30 Excalibur would receive an extra 1,320 Health from max rank Vitality, resulting in a total health stat of 1,600. This outcome is a significant buff, which is not the intention of this system change.

To remedy this, we approached this problem in two ways:

1 - We reduced the overall multiplier for Health, Shield, Energy, and Armor Mods.
Since these now affect Max Rank Warframe stats, these Mods need to scale differently to maintain the status quo. Additionally, we wanted these new values to be as clear and understandable to all players as possible! Here are a few examples of these value changes:

• Vitality: Reduced from +440% to +100% Health
• Redirection: Reduced from +440% to +100% Shield Capacity
• Steel Fiber: Reduced from +110% to +100% Armor
• Flow: Reduced from +150% to +100% Energy Max

Note: These are not all of the Mods affected by this change. We share the comprehensive list further down in this section of the update notes.

Doing some quick math, this means that a Rank 30 Excalibur (300 Health) with a reworked Vitality Mod (+100% Health, applied to the final Health stat) would receive 300 extra Health, for a total of 600. That, in contrast, is a nerf, which we also don’t want to do.

So, our next step:

2 - We adjusted Warframe Health, Shield, Energy, and Armor values to keep the end result of the revised Mods as close to the original values as possible.

With this change, Excalibur’s Rank 30 Health stat is 370. With +100% Health from a max Vitality Mod, his resulting Health stat would be 740, which matches what it was originally.

While this path to the same result may seem a little complicated, the outcome matches our intention: we want players to be able to look at their Health, Shield, and Armor Mods, and be able to understand how they affect the stats they see in their Arsenal.

In addition to everything above, we also increased the base stat values for Warframes so that these revised Mods offer similar value for lower-ranked Frames. To do so, we reduced the amount of Health/Shield/Energy that Warframes earn per rank in half, and transferred the sum of that value to their base stats.

For Armor, this is the one stat that does not increase with your Warframe’s level (with some exceptions). Armor values across the board have been slightly increased to compensate for the Mod changes.

Not to beat a dead Kaithe, but Mods will now be applying to the Max Rank stat instead of the Base Rank. You may look at these numbers and think “nerf” or “buff” depending, but the outcome is that total Modded values are the same, if not a little higher in some cases.

Warframe Stat Changes:

HYDROID
Health: Base Rank - 270 (from 100) / Max Rank - 370 (from 300)
Shields: Base Rank - 365 (from 125) / Max Rank - 465 (from 375)
Armor: Base Rank - 240 (from 225)
Energy: Base Rank - 140 (from 125) / Max Rank - 190 (from 188)

HYDROID PRIME
Health: Base Rank - 270 (from 100) / Max Rank - 370 (from 300)
Shields: Base Rank - 550 (from 175) / Max Rank - 650 (from 525)
Armor: Base Rank - 290 (from 275)
Energy: Base Rank - 175 (from 150) / Max Rank - 225 (from 225)

While there may be significant changes to Warframe Stats and Mod values as a part of this overhaul, the end result is that your Builds should mostly stay the same. The key difference is the added clarity of what your Health / Shield / Energy / Armor Mods do in your Upgrade screens!

HYDROID REWORK

For those of you with an interest in the sea, who wish to use the murky depths to drown your foes, the wait is over! Hydroid has received a rework!

As with many of our Warframe Reworks, a Forma Inbox will be sent to all players at 11:30am ET on October 18th after Abyss of Dagath launches.

The goal of the Hydroid rework was to keep his unique style while making him both easier to use and bringing his power more in line with other Warframes. This means changing how his abilities work through changes to their damage types, removing charging mechanics, and making enemies easier to hit while they are wrapped up in his abilities. Additionally, it meant reworking his passive and removing the Undertow ability, replacing it with the new Plunder ability.

For a closer look at our deadly marauder of the deep, let's dive right in!

Changing Impact and Magnetic Damage to Corrosive Damage and Status

Previously, Tempest Barrage and Tidal Surge both dealt Impact damage, while Tentacle Swarm dealt Magnetic Damage. These have been changed to Corrosive Damage, which can apply Corrosive Status. Corroding Barrage has been a widely used Augment Mod by Hydroid players, which caused Corrosive Status for Tempest Barrage, and due to its popularity, we looked to incorporate its effect into Hydroid at a base level.

We felt changing Damage to Corrosive Damage in Hydroid’s abilities makes them more thematic to the sea while also incorporating Corroding Barrage’s current effect in a meaningful way. With this change in mind, Corroding Barrage will now apply Viral Status instead of Corrosive - more details on that below.

Passive Changes

Hydroid’s previous Passive had a chance to spawn a tentacle when performing a melee slam attack. We have removed that passive entirely and replaced it with an entirely new effect.

The nature of Hydroid’s previous Passive pushed players to a very specific playstyle (regular usage of melee slam attacks), while not guaranteeing anything useful from each individual slam. We wanted to make the passive feel more reliable and impactful.

New Passive: Enemies damaged by Hydroid are more vulnerable to Corrosion Status, with initial status reducing armor by 50%.

Hydroid’s new Passive affects an enemy once Hydroid damages them, lasting until their death. It makes the first instance of Corrosive Status on an enemy remove 50% of their Armor rather than 26%. Not only does this make the first Corrosive Status stronger, but it also means Corrosion Status can reach 100% Armor Reduction with full stacks!

To clarify, this means Hydroid does not need to apply all, or even any, of the Corrosive Status Effects on an enemy. As long as Hydroid has damaged the enemy, the Corrosive Status Effects can be applied from any source and will receive the benefit.

You can see the Passive in action in the Ability clips below.

Removing Charge Mechanics

In an effort to make Hydroid more approachable, we have removed the charge mechanic on Tempest Barrage and Tentacle Swarm. The full charge values will now apply baseline to each cast of the abilities.

For example, previously, an uncharged Tentacle Swarm would have 40% of the tentacles and 33% of the radius compared to a fully charged cast. With this change, both tentacle count and radius will always be the maximum, what a fully charged cast was previously.

This change makes Hydroid’s play more fluid, with more time spent attacking rather than charging abilities for their maximum effect.

Ability Changes

Tempest Barrage:

• Damage dealt causes enemies to stagger, rather than ragdoll.
  • This should make enemies easier to kill, as they will stay in the range of Hydroid’s other abilities and be more open to Headshots.
• The Corroding Barrage Augment Mod has been renamed Viral Tempest and now has a chance to apply a Viral Status Effect, rather than Corrosive Status Effect. It also no longer grants Ability Strength.
  • Changing the Impact Damage of Tempest Barrage to Corrosive Damage meant the Corrosive Status Effect from the Augment was already included. We changed this to Viral to maintain its relevance with the other changes. In light of the punch Corrosive and Viral packs in comparison to Corrosive and Impact, the Ability Strength buff was removed for balance purposes.
• Added new sound effects to go with the ability.

Tempest Barrage staggers enemies instead of ragdoll, making them easier to target.

Tidal Surge:

• Allows some steering of the wave for more control over where Hydroid and his enemies end up when the ability is finished.
• Exiting Tidal Surge early by jumping now also works while airborne.
• Tidal Surge’s base speed has been increased and will no longer scale off Ability Range.
  • This change was made to ensure controlling the wave behaves consistently, including where enemies are deposited when the ability ends.
• Tidal Surge no longer violently flings carried enemies at the end of the surge, and will instead deposit them where the surge ends.
• This should make Tidal Surge a better ability for grouping enemies and quick killing, as opposed to flinging them across the room.
• Tidal Surge now applies Corrosive Status Effects to enemies based on how long they are carried by its waves.
• Tidal Surge now cleanses all of Hydroid’s negative Status Effects.
  • This brings one of the benefits from the Tidal Impunity Augment Mod into the ability directly, granting Hydroid some survivability in his abilities with Undertow’s removal.
• Added new sound effects to go with the ability.

Tidal Surge now carries enemies with the wave, depositing them where the wave ends instead of throwing them forward.

Undertow (Replaced with Plunder):

• This ability has been removed and replaced with Plunder.
  • Undertow was an ability which we feel made Hydroid a bit less fun to play as, or play with. There are two main reasons we decided to replace this ability:
  • It forced the player to remain stationary, while many objectives rely on regular movement.
  • It absorbed enemies without instantly killing them, which could lead to instances of hiding enemies that a teammate was trying to kill.

Plunder:

• A new ability added to Hydroid’s third ability slot.
• All enemies in range will have Corrosive Status Effects remove their armor permanently, increasing Hydroid’s armor and granting bonus Corrosive damage to weapons.
  • This ability is stronger based on the number of Corrosive Status Effects applied to the enemies affected by Plunder.
  • This means with a full stack of Corrosive Status Effects, their Armor will be removed permanently.
• The Curative Undertow Augment Mod has been renamed Rousing Plunder and it causes Plunder to heal Hydroid and his allies within Affinity Range.

Plunder removes Armor based on Corrosive Status Effects on an enemy. It also provides an Armor and Damage Buff, tracked in the lower-right corner of the HUD.

Tentacle Swarm:

• Now holds enemies in a steadier position, making it easier to eliminate enemies locked down by Tentacles.
• If a tentacle’s held enemy dies, it will move to grab a new enemy in the Tentacle Swarm’s area of effect.
• Updated Tentacle sound and visual effects.

Tentacle Swarm now holds enemies still for easy targeting, rather than violently shaking them about.

Hotfix 31.5.6 (2022-05-04)

• Fixed Hydroid's Pilfering Swarm affecting Vitoplast drop amounts from enemies in Void Flood missions.
  • This was the original design intention, as was mentioned in the pre-launch sponsored videos on Void Flood missions. Its core design encourages the use of your parkour skills as the primary way to collect scattered Vitoplast around the tileset, with enemy drops being secondary.

Hotfix 31.5.4 (2022-05-02)

• Fixed Hydroid’s Pilfering Swarm being able to duplicate Voidplume Pinion and Arcane drops from Void Manifestation fights.

• Recasting the ability to change directions will now do so seamlessly while in Tidal Surge form (Hydroid will no longer pop his head out in between casts).
• Fixed spamming Hydroid's Tidal Surge causing the wave FX to stick to Hydroid permanently.

Update 30.6 (2021-08-04)

• Fixed the ability to reach locations where enemies cannot not damage you by using Hydroid’s Undertow.

Update 27.3 (2020-03-24)

• Fixed Heavy Melee Slam Attacks not triggering Hydroid’s Passive to spawn a Tentacle.

Update 27.2 (2020-03-05)

• Armor Change:
  • Hydroid: 200 to 225
  • Hydroid Prime: 250 to 275
  • Why: The conversation surrounding Arcane Guardian led to a significant review of Armor stats on Warfarmes. The Majority of Warframes received an increase in the Armor stat to increase survivability. Compounded with Shield Gating and the numerous other changes covered, we expect a much more fair feeling playing field for all Warframes.
• Fixed a map hole that was only accessible if you were in Hydroid’s Undertow. Like that one scene in X-Men when that one dude is disintegrated into water and slips off the table in a watery terrifying massacre...

Hotfix 27.1.1 (2020-02-11)

• Fixed the Left Hulta Leg Guard being offset when equipped on Hydroid Prime. As reported here: https://forums.warframe.com/topic/1165714-hydroid-severe-offset/

Hotfix 27.0.12 (2020-01-23)

• Hydroid ability videos have been added to his Arsenal!

Update 25.8 (2019-10-01)

Warframe Looting Ability Changes

Warframe Loot Abilities will again be able to yield multiple-drops from already looted corpses. A single enemy can be looted by at most one Ability from each group - which is how it worked before, this just clarifies it. Warframe Looting Abilities have been split into separate functionality groups for clarity:

1. Loot while alive: Ivara
2. Loot petrified: Atlas
3. Loot on death: Wukong, Khora, Hydroid. An enemy can only be killed once, they can’t ‘die’ multiple times.
4. Loot corpse: Nekros, Chesa

These changes stem from a bigger conversation that was addressed yesterday regarding not providing closure on the Loot Frame changes from The Jovian Concord. All the information can be found here: https://forums.warframe.com/topic/1131506-the-mod-booster-and-free-to-play/
