Shield — guide

The hero's health bar is increased by a shield effect for X turns. Incoming damage is calculated using the normal formula, but the shield absorbs it first (except for damage that ignores shields, as specified in the skill description). When the buff expires or the shield value reaches 0, the shield disappears and subsequent damage is dealt normally. Note: damage dealt to the shield is not counted as damage to the hero, so lifesteal effects will not trigger.
