SH is one of your three physical defenses, along with AC and EV. It allows you to completely negate physical attacks (both melee and ranged) and some magical attacks. Unlike AC and EV, you have no innate SH score. SH gained from wearing a physical shield is governed by the Shields skill; magical shields are unaffected.
You can raise your Shield stat through the following means:
- Wearing a shield
- Wearing an amulet of reflection
- Casting Condensation Shield
- Having the Large Bone Plates mutation
- The Shining One's "Divine Shield" ability
- Qazlal Stormbringer's "Storm Shield" ability
- Drawing the Helm card
