Is Irisalis a good Grass DPS?

The catch is energy: Irisalis has high EP consumption, and her whole kit is built around it. Each volley from her clones that hits grants a stack of Dance Power, and at nine stacks her next skill costs less energy. The build article walks through that combo in full.

The damage has real numbers behind it. Her base crit rate is 15%, which is high, and her exclusive signature held item, the Floral Rainbow Feather, gives her clones a damage and crit buff at its core tier 2 effect, including 30% damage amplification. That bonus is also described as applying to Irisalis herself. She is effective in Hollow Battle Interlink, where her high damage carries.

She is also harder to remove than most damage dealers. When she is defeated she turns back into a flower that blooms again and restores her vitality, once every 180 seconds.

Which team to run Irisalis in

The recommended Irisalis grass team is Irisalis, Turbo, Leafy and Somni Wing.

Keep Melabloom out of it. Both rely on ultimate charge, so the two have limited synergy and get in each other's way.

Plan on her being your main source of break as well as damage. That is why her capability awakening goes into Attack first, then Regen, with Break invested in afterwards.

Not settled: How much the nine-stack Dance Power discount saves is not settled: it is given both as half the usual cost and as 50 EP less.
