A champion with a shield that blocks any type of damage.
- Shields are not to be confused with similar effects like
Spell shield and visual shielding effects like 
Eclipse.
Shields are an addition of hit-points that absorb damage in place of actual 
health, this distinction separates the amount from calculation by health based effects like 
Primordial Burst, 
Blade of the Ruined King or 
Death from Below. It may persist on the recipient to absorb a set amount of damage (shield strength) and/or until the duration runs out (shield duration). When shielded from multiple sources, damage taken is mitigated by the shield that will expire the soonest, with the exceptions of 
Adaptive Defenses and 
Black Shield, which take priority over all other shields.
The unit's resistances (
armor and 
magic resistance) will still mitigate the damage before being absorbed by shielding. The shield's strength can be increased by 
heal and shield power.
Shield types
An active shield is indicated on the champion's overhead health bar in a distinct color.
- Normal shields: They absorb all types of damage (physical, magic and true), and appear greyish-white.
- Magic shields: They only absorb magic damage, and appear purple.
- Physical shields: They only absorb physical damage, and appear orange.
