Arcane Protection Shield (Greater)

This magical coin attaches to your armor or body (your choice) and reshapes into an arcane brand featuring a shield. Upon finishing a short rest, the brand grants you 2d8 + 4 temporary hit points as it forms a thin barrier of protection along your body that can potentially absorb the impact of any incoming attacks.  

Notes: Bonus: Temporary Hit Points, humanoid creature, Warding
