Arcane Shell

An arcane barrier of shimmering force surrounds you, shielding you from harm. While the spell is active, you gain a protective shell with its own pool of hit points equal to 3d8 + your spellcasting ability modifier.

The shell absorbs damage directed at you. Any damage you would take is subtracted from the shell’s hit point total instead. If the shell's hit points are reduced to 0, the spell ends, and any remaining damage carries over to you.

While the shell is active, you gain the following benefits:

• +2 bonus to AC.
• Advantage on saving throws against being grappled, restrained, or knocked prone.

At Higher Levels. When you cast this spell using a spell slot of 4th level or higher, the shell’s hit points increase by 1d8 for each slot level above 3rd.
