Echo cost
Stay in cost cap. A pretty 4-cost echo that breaks the set is a dps loss.
Farm routes sit in additional guides.
Intro and outro
Swap on the outro, then intro immediately. Dead air in the rotation is lost damage.
Build the support that actually enables the main, not a third DPS that never gets field time.
Tower floors
Read the floor buff. Bring the element it wants. Brute force with last week’s team stalls.
Spend energy on talent mats before you reroll every echo twice.
