I'm honestly very skeptical about this conclusion. According to all I've read the Seagorgets only raise the fTP modifier by 10%. On a WS like Gekko which naturally has a 150 > 200 > 250 progression, whenever you WS with Hagun at 100% TP, the gorget should only raise your damage by 5% (10% is 5% of 200%). Yet in the tests I did, it seemed to raise it by a flat 10%.
I realize some people may say, show me the evidence. But my main question at this point is, if this behavior I observed is true (assume this), does that disprove the fTP mod? Or am I misunderstanding. Is it a 10% bonus to the fTP itself, not +10% fTP?
