@Raitou My proposed changes for chakra scalpel:
-Scalpel does not stack with agi basic attack damage and cannot be used with tai weapons.
(I know that this is not currently feasable with your current tools, but this is what is needed to balance the jutsu...)
-Chakra scalpel goes back to instant cast with 1 sec self stun.
-Base damage changed to 0 at all ranks
-Scaling changed to 0.4 per chakra point Effect on Basic attack damage (Old damage calculated with 5 agi AKA 3 base dmg) Chakra Stat - New damage (Old damage)
40 - 16 (18)
60 - 24 (24)
80 - 32 (30)
100 - 40 (36)
120 - 48 (42)
140 - 56 (48)
160 - 64 (54)
180 - 72 (60)
Note that any build with more than 130 chakra either has lower hp than average or is missing multiple second mastery jutsus.
Effect on Basic attack damage for some popular tai/med builds
IF USING SCALPELS Stats - New damage (Old damage)
35 agi, 130 chk - 52 (53)
70 agi, 110 chk - 44 (57)
100 agi, 80 chk - 32 (57)
110 agi, 80 chk - 32 (60)
Note here that the current dmg is GOING UP with higher agi build while also getting cast time reductions AND insane attack speed!
Hope these numbers, even if they dont convince you on the my suggestion, can show how dumb the current jutsu is...
High agi tais get way too much out of the jutsu while having insane agi benefits.
