Turn to shadow

You exchange some material energy to the shadow plane and replaces it with illusions. When you cast this spell against a damaging spell, you reduce the damage of the spell with 6d8 damage.

If the spell is of 3rd level or lower, you automatically make the reduction. Ohterwise, if the spell is of 4th level or higher, you must make an ability check using your spellcasting ability. The DC equals 10 + the spell's level.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, you can choose to either increase the damage reduction die by 1d8 for each level higher than 3rd, or you can choose to automatically reduce the damage of the spell, if the spell's level is equal to or less than the level of the slot you used. You cannot choose both options.
