DI, SSI, HCI, HML, Slayer, HSL, HLL, HLD, Hit Area, Hit Spell, 1 FC.
I'd rank the ones in bold as most important for the template. Hit Area only for spawning weapons. Hit Spell only for Blackthorn Captains.
Although I get that you've got Med on there for the passive regen effects, it's kind of a waste, as you will most likely have HML on every PvM weapon which is always going to be better, even swapping to a no SSI slow Heavy X Bow for a high HML is quicker than regen. If it was PvP then I'd say yes keep the Med. I'd say swap it for Bushido primarily as Perfection/LS/Momentum Strike/Confidence are all very good. Or 60 Necro/60 SS. Or a melee skill for Whirlwind. Or even Focus and make the suit non Med 55 LMC, which will benefit Spellweaving's bigger costs.
