-Double Blades
-Rank 3
-Gain 1.2 attack poer for every point of speed you have.
-Increase attack speed by 45% (Not quite as OP as it sounds since it literally just adds that percent and not 45% of the total)
-Increase bone resource regeneration by 30%
Problem- Gives 1.2 attack power for every 1 speed. With this and 30 speed bring my attack power from 90 > 126.
Which is a 40% boost. Otherwise the same amount of power as someone could get 48 Nin.
Suggestion- Which I get what he was going for there since you're using a weapon in each arm now, could pry be toned down to half that and make the ranks give .2 > .4 > .6. so a 20% attack power boost (Say keep some of it cause kaguya don't really have anything else in ST giving damage boost)
Problem- Bone regen, as it stands I NEVER run even close to low on energy, I can spam willows bullets ect. all day and never hit less than 2/3 max energy, which also makes snap regenerate useless and this is without the regen from Doubel Blades even.
Suggestion- Regen is more than enough without the regen from double blades so I say take it's regen out (since it's not needed anyways) and give is a crit nerf, since moves almost always crit anyways to balance out higher attack if kept and or make normal melee attacks get the buff since there being hit by 2 swords. o.o
Otherwise for a comparison, Hardened bone sword gives a 36% damage boost (slightly less than double atm), increased crit rate (75% so a lot), and reduces bone regen and attack speed by 30%.
So less of a damage boost, higher crit rate, slower bone regen and loose attack speed.
