Notes[]
- Fires in a quick 4-round burst, but then has a burst cycle time of 4 times the inverse of the Firing Rate, otherwise known as the Seconds Per Shot. The delay in seconds between the first shot of each burst = 4 / (modified firing rate), e.g. with a maxed
Speed Trigger the cycle time is 4/(0.91 x (1 + 0.6)) = 2.75 seconds between bursts. The default rate is one burst every 4.4 seconds. - Missiles have homing properties, allowing the whole salvo to reliably hit small and/or agile targets such as Ospreys.
- In the event the target dies before the missiles reach it, the missiles will continue to travel in a straight line.
- Given the homing properties, it can accurately land hits even when equipped on a very long range companion like Diriga using Calculated Shot, however the long travel time in this situation can still cause difficulties since the enemy may have time to move and get a terrain obstacle between it and the missiles at a safe distance.
- Note that MOAs will 'lose interest' in a target if the player does not continue to target it. This appears to happen faster than with other companions, with MOAs firing, on average, three bursts, and sentinels firing approximately five before losing interest.

Patch History[]
Update 32.0 (2022-09-07)
- Headshot Damage Changes
During playtesting, the ammo changes alone weren’t enough to significantly change things for AoE weapons. So instead of tightening these values to be overly restrictive, we chose to address other factors that make these weapons so strong, such as headshot damage.
Our approach here is two-fold, to reduce the impact of headshots for AOE weapons, but to also make precision headshots pack a larger punch overall.
- Radial damage no longer gains extra headshot damage or triggers headshot conditions.
- This is primarily targeted at the Ignis Wraith - as a “flamethrower” weapon, it’s hard to imagine a blanket of elements being precise enough to target weak points specifically. Explosive projectiles themselves can still land headshots, so there is still a reason to aim with most weapons for maximum damage.
Update 30.9 (2021-11-11)
- Fixed the Terminal Velocity Mod not applying projectile velocity changes to Sentinels using the Helstrum weapon.
Hotfix 29.1.2 (2020-09-22)
- Fixed some Sentinel and Moa Weapon types not getting affected by Magazine related Mods (notably Helstrum).

- Fixed Helstrum missing from the Codex and an inability to Chat link it.
