Wild Shield

You surround yourself with the forces of chaos. Wild lights and strange sounds surround you, making stealth impossible. While wild shield is active, you can spend a reaction to absorb a spell that targets you or whose area of effect you are within. An absorbed spell has no effect, but absorbing a spell causes a chaos magic surge as if you had cast a spell, with you as the caster for all magic surge effects, unless otherwise specified.

Wild shield ends when the duration expires or when it absorbs 4 levels of spells. If you try to absorb a spell whose level exceeds the spell levels remaining, make an ability check using your spellcasting ability. The DC equals 10 + the spell’s level – the levels wild shield can still absorb. If the check succeeds, the spell is absorbed; if the check fails, the spell takes its full effect. The chaos magic surge happens regardless of whether the spell is absorbed.

At Higher Levels. When you cast this spell using a spell slot of 5th level or higher, you can absorb 1 additional spell level for each slot level above 4th.
