I've had to make it the moment I saw ghosts aren't immune to being stunned, and once I was done, I've decided to share, 'cause why not.
Transcription: Four panel comic. First panes shows a ghost saying "They finally went to sleep. It's time to strike." while phasing into the material plane, indicated by turning from green to purple. In second panel the ghost attacks someone on the ground with its claws, causing them to yell "YEOUCH!". Third panel shows that it was a monk, and they perform a stunning strike on the ghost. Both silhouettes are grey on this panel. On fourth panel the ghost is stunned and surrounded by grey silhouettes of a barbarian with an axe, rogue preparing to backstab, and a caster casting fireball.
