[Snake]

What Soapy said, it does nothing but give +3 FP to accessories/shoes, at least Snakescale gives 5% Poison Resistance on top of +3 HP to every equipment piece but weapons.

I don't think it needs to be changed in weapons at all, it's unique and different from Iron there, problem is only when Ether is used on Torso/Shoes or Accessories, it gives no extra benefits but +3 FP.

That's why I thought it could be good to toss +1 FP recovery for it.
