Orianna shields herself with 
Command Protect
- Shields are not to be confused with similar effects like
Spell shield and visual shielding effects like Eclipse.
A Shield is an addition of hit-points that absorbs damage in place of actual health. Note that Shields are not considered health for health based effects, like 
Primordial Burst, 
Blade of the Ruined King or 
Death from Below, when calculating their effects. It may persist on the recipient to absorb a set amount of damage (shield strength) and/or until the duration runs out (shield duration). An active shield is indicated on the champion's overhead healthbar in a distinct color.
The unit's resistances (armor or magic resistance) will still mitigate the damage before being absorbed by shielding. The shield strength can be increased with some items and runes.
Shield types
- Normal shields: They absorb all types of damage (physical, magic and true), and appear grey.
- Magic shields: They only absorb magic damage, and appear purple.
- Physical shields: They only absorb physical damage, and appear orange.
