History of Redirection

Redirection is a Season 12 Legendary trait. Damaging rank-and-file combatants increases your damage against more powerful ones.

Mechanics

Hits on minor combatants build up stacks of Redirection. Hits on Elite or higher-ranked combatants spend stacks for a damage bonus per stack consumed. Reported stack caps differ between sources (20 and 30 stacks), so the exact cap depends on the version.

Weapons

It is a Perk 2 option on Returned Memory, though that weapon's recommended PvE and PvP god rolls do not use it. It also rolls on many other weapons in the list below.
