Wildshield

This spell envelopes you in a swirling mass of colors, completely concealing you from view outside of the shield though you still view your surroundings normally. The Wildshield has 90 hit points and completely absorbs incoming damage from spells, effects from magic items such as wands, and Wild Magic Surges. The shield absorbs energy from explosive magical attacks that detonate near you such as the spell Fireball. The Wildshield cannot regain hit points by any means.

A Wildshield remains until cancelled as a free action or when it reaches its capacity for absorbing magical energy. If the capacity is met exactly, the shield vanishes with a small pop. If the final magical absorption exceeds the capacity of the shield, it explodes, negating the final incoming spell in the process and triggering a Wild Magic Surge.

Using a Higher-Level Spell Slot: The hit points of the Wildshield increases by 30 for each spell slot level above 6.
