Shield Potion

A Shield Potion is a consumable blue flask that grants a separate shield bar sitting on top of your health. A full-size potion restores 50 shield over a few seconds, and you can hold a maximum of 100 shield in total; smaller Mini Shields give 25 each up to a cap of 50.

Shield absorbs incoming damage before your health does, so topping up to full before and after fights is essential survival play. Keeping a stock of shields and other healing items lets you reset quickly between engagements and resist being third-partied.
