>I want big numbers to kill a boss
1) Start with Rover, fill the forte gauge with aerial basics, echo, ult, outro to Cia
2) intro, skill, jump cancel, mash basics until she fills the forte bar, jump cancel, mash normals until she fills the forte bar, jump cancel into aerial heavy, echo, ult, outro into Carty
3) into, basics until she gets the mid sword, echo, skill, plunge, ult, basic chain, heavy into basic, skill, enhanced skill, ult (big fuck you sword)
The enemy should be dead. Repeat if it's still alive.
Since all three use Fleur's sword in the main slot, you can use the echo skill whenever you want. In Cia's case the best opportunity is during her forte succ, you're bound to hit all targets.
