Hit : 14 (2d10 + 3) bludgeoning damage, and the target is  grappled  (escape DC 13). Until this grapple ends, the target is  restrained . \n'b'  Leach Mind . The myzoform latches its many lamprey mouths on a creature  grappled  by it and feasts on its memories. The creature must make a DC 15  Wisdom  saving throw. On a failed save, the creature takes 40 (9d8) psychic damage and permanently loses 1 minute\xe2\x80\x99s worth of memories, which are replaced with an indistinct haze. On a success, the creature takes half as much damage and doesn\xe2\x80\x99t lose memories. Creatures that are immune to being  charmed  don\xe2\x80\x99t lose memories. \n'b'\n'b' ABOUT \n'b' Myzoforms come about when a mundane lamprey is accidentally exposed to strange and powerful magics-be it from the monstrous aboleths, wild sorcerers, or even natural sources. As a result of its exposure, the lamprey becomes presapient, allowing it to feed on and digest creatures\xe2\x80\x99 memories as easily as a normal lamprey sucks blood. \n'b' When such a pre-sapient lamprey attaches itself to another pre-sapient lamprey, the two create a kind of feedback loop as their minds interconnect and feed on and regurgitate one another\xe2\x80\x99s increasingly broken and bizarre memories. \n'b' The lampreys then look for more lampreys to turn into their body, and the process snowballs until a myzoform is born. \n'b' At this stage, a myzoform can survive on its own experiences and memories, but most myzoforms find themselves addicted to the fresh memories of other creatures. These thirsty creatures are often found haunting towns, cities, and other urban centers rich with potential prey on whose minds they can absorb. \n'b' When a myzoform strikes from the shadows and latches onto the mind of an unfortunate local, they absorb everything personality, memories, knowledge and leave in their wake only an amnesiac. \n'b' The most gluttonous and malicious myzoforms have fed on countless minds throughout their lives, and they might contain hundreds or even thousands of consumed personalities. As the number of minds inside them increases, only the most powerful myzoforms can stay in control; most eventually break down and self-destruct as their collective minds become a civil war of different fears, ideologies, and motivations. \n'b' Although some myzoforms can be genuinely malicious, those are rare. Many myzoforms feel highly guilty over their nigh unstoppable impulse to feed on other sapient beings. \n'b' Some rationalize their behavior by saying they can\xe2\x80\x99t control their impulses, while others might try to cure themselves of their curse and seek outside help to overcome their insatiable addiction.'
