Diminishing returns

Diminishing returns (abbreviated DR) is the mechanic that makes certain spells (mostly ones which cause loss of control of your character) less effective if they are used frequently within a short period of time.

— DRs are specific to CC type: for example, stuns affect other stuns, but not incaps or other CCs.

— DRs are target-specific: you can stun one player, and then another one for full duration.

— DR timer starts once the first CC effect fades and lasts for 20 seconds

— During the DR timer, the duration of the second effect of the same type will be reduced by 50%, and then by 75% for the third one.

— The 4th and next effects will be resisted until the DR timer ends.
