This short video from the upcoming Sword Coast Legends video game demonstrates an illithid wiggling when hit by energy blasts. "Coming to Sword Coast Legends: Mind flayers, also called illithids, are the scourge of sentient creatures across countless worlds. Four tentacles snake from their octopus-like heads, flexing in hungry anticipation when thinking creatures come near." Sword Coast Legends is currently slated for release on PC on September 29th, with console releases later in the year.
