Traits

Damage Transfer.

While it is grappling a creature, the memory web takes only half the damage dealt to it, and the creature grappled by the web takes the other half.

False Appearance.

If the memory web is motionless at the start of combat, it has advantage on its initiative roll. Moreover, if a creature hasn't observed the memory web move or act, that creature must succeed on a DC 18 Intelligence (Investigation) check to discern that the memory web is animate.

Memory Flood.

When the memory web is reduced to 0 hit points, it discharges any memories it consumed over the past 24 hours in a telepathic deluge. Hazy, dreamlike visions of these discharged memories lodge in the minds of creatures up to 120 feet from the memory web.

Actions
