Absorption shield

Absorption shields refers to the game mechanic which grants temporary health to a champion for some time. These shields absorb a set amount of damage before it dissapears, whether because it reached its capacity of damage absorption or because its duration ran out.

Most of these shields are granted by champion abilities.

Types of Shields
Absorption shields are classified by the type of damage they absorb. Most of them absorb all types of damage, including true damage. Magic shields absorb only magic damage, so physical and true damge will just ignore the shield. The majority of absorption shields take the champion's resistances on account when receiving damage.

Spell shields, which allow to completely block the effect of one single ability, are not considered a type of absorption shields.

Some "shields" grant armor, magic resistance or damage reduction when activated, as these don't give any "temporary health" they are not considered absorption shields.
