basically you want to be able to activate galeforce (a 5 cd special) in one turn, so you need a lot of special acceleration. heavy blade or flashing blade activating is enough as long as you get counterattacked and double your opponent (5 cd to start, 3 cd after your first hit, 2 cd after they counter, charge after you follow up). but if you attack a ranged enemy (who can’t counterattack), you won’t be able to get it off unless you have a slaying effect in your wep or time’s pulse (for infantry) or some type of support.
velouria is notable because her prf allows her AND her support partner to start at 3 instead of 5, even if they are cavs or fliers who otherwise lack easy special acceleration. so all she would need is flashing blade or time’s pulse and she and her partner could possibly take out 4 units by themselves in one turn, and then get danced and ko the rest. if they are infantry, both could even get guaranteed galeforce triggers by getting it down to 1-2.
