Xhükan’s Spite

Calling on the energies of chaos, you attempt to pervert a creature’s spellcasting process. 

If the creature is casting a spell of 2nd level or lower, it is forced to roll on the Wild Magic Surge tables.  If it is casting a spell of 3rd level or higher, make an ability check using your spellcasting ability.  The DC equals 12 + the spell’s level.  On a success, the creature must roll on the Wild Magic Surge tables.

At Higher Levels. When you cast this spell using a spell slot of 3rd level or higher, the interrupted spell will cause a wild surge if its level is less than or equal to the level of the spell slot you used.

This spell has no effect on spells of 6th level or higher.
