Shield of Retribution

The Shield of Retribution is a silver and marble shield that was found by the Mighty Nein on the Yuan-ti abomination guarding the heart of the Temple of the False Serpent on Urukayxl.

Appearance
The Shield of Retribution is a beautiful polished silver and marble shield. It is exquisitely crafted and shows no signs of wear.

History
The shield was found in the possession of the yuan-ti abomination guarding the pool where the hydra lurked in the Temple of the False Serpent on Urukayxl. Nott took it when the party killed the abomination and used it to sled Caduceus down the side of the temple during the party's escape from the collapsing temple. Caleb later identified it, and Caduceus took it. He used it for the first time in the battle at the second temple binding Uk'otoa.

Features
The shield adds a +1 to the user's AC in addition to the normal +2 shield bonus. If a creature misses a melee attack against the user, the user can use a reaction to blast the attacker with 4d6 arcane force damage. If the creature fails a strength saving throw against the user's spell DC, the creature is also pushed back 20 feet.

Matthew Mercer has more than once discussed the propriety of having the item use its own specific DC for the strength saving throw and possibly do half damage on a save.
