The Brainsucker is a humanoid creature with a pale blueish appearance with a slender figure, elongated limbs, and a mass of tentacles emerging from its face. Despite its frail appearance, it can run surprisingly fast and attacks with vicious swipes and punches. Often times he is unstaggerable.
The Brainsucker is capable of a dangerous grab attack that damages the player and drains Insight; a tentacle will emerge from its head which it will use to impale the Hunter's skull.
There are two variants of the Brainsucker, the hooded version is capable of using magic attacks that paralyze the player and leave them vulnerable to a grab. They are Kin, as such, their blood is gray instead of red.
Brainsuckers are often found guarding items and are usually unaware of the player which leaves them vulnerable to Visceral Attacks. Once they detect the player they will relentlessly attempt their grab attack, whilst it is possible to interrupt them, the timing is very tight so it is recommended to sidestep their lunge. Backstepping is not advised as they will propel themselves forward and will often catch the player mid-evade.
The Hooded variant of the Brainsucker will use paralyzing energy blasts that will immobilize the player. It will fire several rapid blasts at a distance and use an AOE blast at close range. Should it succeed in trapping the player, the Brainsucker will sprint towards them and attempt a grab.
Brainsuckers, being a Kin type enemy, they are weak to thrust attacks and bolt damage, however, they are also vulnerable to both fire.
Despite their low health, they are surprisingly resilient to most physical damage so it is advised to infuse weapons with elemental attacks if facing them during close combat.
The grab attack of the Brainsucker will always drain 2 Insight.
The Brainsucker is Kin, but his weakness doesn't extend to only thrust and Bolt. He is also very weak against fire.
