The only skill here that doesn't sound correct is Cripple Leg and Arm, which have traditionally always been highly costly and could eventually use a tune down, everything else seems to be in line for what they are, high range, granting additional effects or being AoE. Plus I believe how much mage spells are being gauged at are severely undercutted beyond what they actually are in most cases, plus most skills I am aware of cost within the 10-20 mark anyway, with duelist having a few exceptions.

160 FP sounds terribly low, I suggest building tanninheart, as usual.

I do think it's silly their costs are about as much as mage spells are (more in some cases). If the intent is to make these require some opportunity cost, then they probably shouldn't be as mid as they are for what you're paying.

And to compare to other physical skills, Rapid Kick (which is one of Verglas' cheapest skills):


Yeah, 10-20 seems appropriate for most of the archer skills, I don't see how they're comparable to mage spells in cost, I would suggest checking into the many ways to boost your max FP now if you're still struggling.
