Daigon's Divine Wrath

You attempt to call on your deity or patron to stop the casting of a spell by striking down the caster.  If the creature is casting a spell of 5th level or lower, its spell fails and has no effect as well as your deity or patron strikes them down for 5d12 radiant or necrotic damage(based on your Deity/Patron). If it is casting a spell of 6th level or higher, make an ability check using your spellcasting ability. The DC equals 10 + the spell's level. On a success, the creature's spell fails and has no effect as well as your deity or patron strikes them down for 5d12 radiant or necrotic damage(based on your Deity/Patron).

At Higher Levels. When you cast this spell using a spell slot of 6th level or higher, the interrupted spell has no effect if its level is less than or equal to the level of the spell slot you used and for every spell slot of 6th level or higher the damage increases by 1d12.
