BiS claw is
2 sin
fools
2os (2x Lo)
if there is ed% on it, it means you are missing one (or more) of the 3 most important prefixes.
Ideally on a GT/RT, cuz WSM is what matters most for blade sentinel.
Need 42 ias while using -30 WSM claw, and you should already have 20ias from HL.
So ideally the claw should also have 30ias (the only suffix that matters).
