Rapture (5e Spell)
From D&D Wiki
|Casting time:||1 action|
At a point you select within range a rip in the Time Vortex appears bleeding pure Astral Energy in a 30-foot long, 10-foot wide line or a sphere of 20-foot radius, the sphere or the line remains until the end of the spells duration.
This area is now considered difficult terrain, any creature that starts or ends its turn in the Vortex must make a Wisdom saving throw on a failed save the creature is afflicted with short term madness for 1d10 minutes. If a creature already has short-term madness he now has long-term madness for 1d10 x 10 hours and if a creature already has long-term madness he or she is made indefinitely mad (Ask the DM to roll from the madness tables on page 259-260 in the Dungeon Masters Guide).
