Elite instances are versions of challenges, duos, alerts, and raids found in the On Duty menu, with significantly harder to beat enemies and better rewards. They may also feature additional mechanics not present in the regular versions.
Apart from harder enemies player characters are only allowed two Knock Outs per boss fight in elite content, reviving at 20% health. On the third KO reviving will not be possible and the player character will be out for that stage of the instance.
Elite Plus is a version that is even harder with even better rewards. Only 1 rally is allowed, and players revive at 10% health. Elite Plus was first introduced with the Dark Knights episode.
Elite and Elite Plus instances share loot locks with normal and event versions.
Elite Gear can only be purchased after earning enough renown through Elite instances.
