Review

Helm is a good Burst III unit that provides a lot of utility for the team and lifesteal when using burst skills, but has low damage compared to other Burst III units.

Skill 1 procs with each last bullet in her magazine, increasing the critical rate of normal attacks, meaning you want to avoid getting max ammo capacity on her OL equipment or using cubes like Bastion.

Skill 2 provides a permanent damage buff to interruption parts which is always welcome for boss fights. This skill also gives an ATK buff when entering full burst for 10 seconds, so you can take advantage of this skill even if you are not bursting with Helm.

Lastly, the best part of her kit, her burst skill gives lifesteal to everyone in the team and deals some damage, even tho it’s quite underwhelming compared to other burst 3 units. The lifesteal is amazing, but there’s a catch, it’s based on the attacks of each unit.

This will be good for assault rifles and machine guns but quite bad for most rocket launchers and sniper rifles. Still, she should be more than enough as the only healer in your team and you will see her used in almost all raids content.

Should you reroll for Helm

She’s not a bad option and a pretty good waifu. If you want to run a sniper team or have a sub Burst III that can heal by providing lifesteal, you can reroll for Helm, but there are better options.

If you are keen on rerolling, consider checking our guides to see what are the units you should be aiming for.
