Intensify, and weapon that inflicts 100 damage per shot, a max rank Roar will increase the total damage to 100 × (1 + 0.5 × (1 + 0.3)) = 165. - With a weapon modded with maxed Serration, which inflicts 100 damage per shot, a max rank Roar will increase the weapon's total damage to 100 × (1 + 1.65) × (1 + 0.5) = 397.5.
- With a weapon modded with maxed Serration and maxed Bane of Orokin, which inflicts 100 damage per shot, on a Orokin, a max rank Roar will increase the weapon's total damage to 100 × (1 + 1.65) × (1 + 0.5 + 0.3) = 477.
- For example with a Warframe modded with maxed
- As faction bonus damage, the bonus is used twice in the calculation of status damage.
- For example, with a weapon that inflicts 100 damage per shot, that procs a slash status, a max rank Roar will increase the damage per tick from the slash to : 0.35 × 100 × (1 + 0.5) × (1 + 0.5) = 78.75.
- With a Warframe modded with maxed Intensify, and weapon that inflicts 100 damage per shot, modded with maxed Serration and maxed Bane of Orokin, that procs a slash status, on a orokin, a max rank Roar will increase the damage per tick from the slash to 0.35 × 100 × (1 + 1.65) × (1 + 0.5 × (1 + 0.3) + 0.3) × (1 + 0.5 × (1 + 0.3) + 0.3) = 352.6819.
- The damage buff is considered Faction Damage Bonus, additive with other sources of Faction Damage, and multiplicative with other types of bonus of damage.
- The effects of Roar are applied to Rhino, allied Warframes, Companions, Hostages, Shadows, Specters, and hacked Shockwave MOAs.
- Allies only need to be in range at the time Roar is cast to gain its effects.
- Roar cannot be recast while active (except with the mod augment Piercing Roar).
- Subsuming Rhino to the Helminth will offer Roar and its augments to be used by other Warframes.

Roar definitely would need a female scream variant for the female Frames. Nothing more stupid than casting a male sounding Roar with my cute little Nova...
The same with Nourish. Having a frame like Wisp or Ember suddenly stomp like a Sumo and growling "UWU" in the most masculine demon voice is weird af
Or you could just cast off the chains of having to see life through lenses of detrimental societal constructs that make no sense.
???
For frames like Gyre, is the bonus activated when you use Roar, or do you have to cast Rotorswell again while Roar is active to benefit?
Does this stack with vaubans overdriver? I'd imagine it stacks multiplicatively because they both are "faction damage"
"The damage buff is considered Faction Damage Bonus, additive with other sources of Faction Damage, and multiplicative with other types of bonus of damage."
Whats the best warframe to put this helminth on? I'm thinking saryn?
Anyone that uses abilities for damage, i use it on Saryn and Volt, great for their nuke builds
What is the "debuff duration multi" the augment gives in arsenal ?
The puncture proc duration from Piercing Roar
Man I'd really love to have the Roar vs Eclipse damage boost explained in a way that doesn't make me feel like the math lady meme.
Is it really just; Roar 'double dips' on things like slash/toxic damage ticks, Eclipse doesn't?
Roar is added with faction damage bonus (usually bane mods) and then multiplies with everything else and then applies a second time when status effects do damage.
Eclipse does not add with anything and multiplies at the end and applies to mostly weapons only
Damage number you see:
(base dmg) x (element) x (crit) x (faction mods + roar) x (eclipse)
But roar double dips DoTs.
So if you play with a focus on direct damage AND you use faction mods, eclipse is better
If you play on direct damage and do NOT use faction mods, eclipse and roar are equal
If you play with DoT, roar is always better
Remember that Eclipse also interacts with CO and gun CO. The final damage multipliers from CO and gun CO are additive to hitscan weapons and multiplicative to projectile weapons (with some exceptions). These CO multipliers affect Eclipse and applies it either additively or multiplicatively depending on the weapon you're using. CO and gun CO does not apply to AoE weapons, therefore has no interaction with Eclipse; standard Eclipse bonuses still apply to the weapon itself however.
Multiplicative:
Damage = Base * (1 + Pure Damage Mods) * (1 + Eclipse) * (1 + CO Mods)
Additive:
Damage = Base * (1 + Pure Damage Mods) * (1 + Eclipse) + (Base * CO Mods)
Does roar affect thrax? Its a faction damage bonus but thrax is considered unaffiliated so i assume it doesnt work?
It's technically not 'faction damage', it just behaves the exact same way a faction damage mod would - a final multiplier onto the damage you're dealing to an enemy. In theory, it works on literally everything, even containers I think.
Do you need to have the buff on cast of an ability for it to boost damage or can it be applies afterwards?
Say you cast kullervo's 4, that lasts a while, then you get the rhino buff, does the ult now do more damage? or you need to have the buff already when you cast it for it to work.
What happens if you have the 4 active and the rhino buff runs out? do you keep the bonus damage for the duration of your ability or does damage decrease when rhino runs out?
Roar applies its damage buff even when an ability is already active.
Can you double stack roar? Like if you have another rhino on your team or a specter and you both use it?
Multiple Roars do not stack.
Multiple Roars do not stack. A stronger Roar will overwrite a weaker one.
However if a weaker is cast, so that it last longer than a stronger (i.e., it is cast right before the stronger ran out or has higher duration due to increased Ability Duration) it will boost the damage after the stronger ran out.
DE need to allow us to change the ability color
Cant you do that by changing the energy colour in the customization?
No, it's stuck with that yellow-goldish glow
Does it increase the damage output of other abilitys? for example Saryn 4 or Mirage 2 with explosive legerdmain?
That confuses so many people. I constantly see people claim that Eclipse always gives the max damage boost, but the inconsistency is very often not worth it.
DE should either make the percentage update with the actual value, or just nerf the damage percentage and always make it the exact same, regardless of light level.
(also yea, Eclipse is for weapons, not abilities)
Even if eclipse is at half its value, its still much more potent than roar. Energy cost is 25 as well. It's worth just to put on all frames for the circuit because its bright everywhere
Eclipse is so tile dependent it's not worth using on anyone if you have Roar and basic Bane mods...
This will finally be fixed with Dante update. Rejoice.
Does Roar increase Power Strength of other warframes . I wanted to know, an example: does Nekros with Shield of Shadow not at 90% , and after roar is damage reduction increased?
No
Nope, the damage bonus from roar is counted as applying a faction damage bonus, rather than increasing ability strength.
Does not double dip for the heat procs of Thermal Sunder
I wonder why
Almost as if gun damage and melee damage are separate from warframe powers
Except that Roar boosts all damage, not just weapon damage. So it applies to abilities too. Which is why it's weird that thermal sunder acts differently.
Although @ OP, how do you know?
It definitely should add faction damage to thermal sunder
OP here. I just tested it again and it's actually double dipping for Thermal Sunder. I doubt it was changed, so I guess I'm just hopeless. This test, I had a 200 str Rhino, Roar giving +100%, single cast tick damage of Sunder went from ~1k to ~4k.
A shame the piss aura doesn't recolor. Kind of a fashion breaker.
Its a beautiful golden sheen!!!
Does it affect the user?
"...increasing the damage output of himself and his allies..."
I'd like to think OP is referring to the operator.
Does it affect ability strength
No. It is affected by ability strength though.
"...bonus damage to all sources..."
"While Warframe ability damage is increased, Roar is not an increase of Ability Strength."
I think this is what OP is asking.
Does roar works on melee weapons?
Yea
"...bonus damage to all sources..."
Fun fact: the normal version and weakened Helminth version seem to stack with each other, at least in the UI.
When applying to status procs, it looks like roar only adds up with the faction mod once, the numbers were ~1.5% off, so I'm not 100%, but looks like the damage ends up like this:
X*(roar+faction mod)*(roar)=final
Try Helminth's Empower with Roar....Magic....
I wanna test it on Protea's Passive ehehehehe (also to test the DoT of her turrets)
