Cabel's Ruin (Dormant)

Wondrous Item

Legendary Requires Attunement

This cloak of dark leather and gold trim seems to occasionally shimmer with small sparks of blue energy across the shadowed lining. Dormant State. Cabal's Ruin has 4 charges and regains 1d4 expended charges daily at dawn:

When the wearer is targeted by an enemy's spell, they can use their reaction to have the cloak swallow part of the spell, gaining a number of charges equal to the spell level of the triggering spell. The wearer is still subject to whatever effects the spell would normally inflict on them. The ability cannot be used again until they finish a short or long rest.
When the wearer hits with an attack, they can expend a chosen number of charges from the cloak which deal an additional 1d6 lightning damage per charge expended on one of the targets of that attack.
