Robe of Shards

6th-level abjuration (clockwork)

Casting Time: 1 action

Range: Self

Components: V, S, M (a metal shard)

Duration: 1 minute

You create a robe of metal shards, gears, and cogs that provides a base AC of 14 + your Dexterity modifier. As a bonus action while protected by the robe, you can command bits of metal from foes fallen since you cast the spell to be absorbed into it. Each infusion of metal increases your AC by 1 to a maximum of 18 + your Dexterity modifier. You can also use a bonus action to dispel the robe, causing it to explode in a shower of metal debris that does 8d6 slashing damage, plus 1d6 per point of AC added from fallen foes, to all creatures within 30 feet of you.
