Aegis of the Fallen

This shield grants a +1 bonus to AC. Once per long rest, if you are reduced to 0 HP, you drop to 1 HP instead and emit a blinding flash of radiant energy. Enemies within 10 feet must succeed on a DC15 Constitution save or be blinded until the end of their next turn.

"This shield bears the crest of a long-dead Valcrest knight, its golden emblem now tarnished with age. Yet, when grasped in battle, it hums with the resolve of those who never fell."
