The Mind Suckler is the adult version of the SucklerANMC and can be a pain to deal with. They are typically found resting on buildings and will react to Aya's attacks on contemporaries to attack her. A Mind Suckler's attack abilities are very dangerous if Aya does not have enough room to move around.
The are several ways to knock Mind Sucklers to the ground. Reducing it's HP 30 or less will ground one. Buckshot is effective in bringing down a group of them with a single shot. Combat Light also works without having to commit to damaging them one at a time. Once grounded, Mind Sucklers are completely defenseless and can be killed with little effort.
