| Mythic Rhythm|
Landing a third (Combo) hit from a Primary skill increases the damage of the next damaging skill that costs Spirit by 40%.
Mythic Rhythm is a Monk passive skill, unlocked at level 68.
The damage buff is multiplicative, but does not stack, and is consumed on cast. Therefore, the Monk needs to deliver 3 blows with a Primary attack before each Spirit-consuming skill cast for maximum effect.
The damage buff only applies to skills actually cast by the character, not triggered by items and other effects.
