This is my Arcane build. Well, by this point it's a Strength hybrid because laser sword... but I also have the Kos Parasite handy. And no gems for it.

I WANT TO WHIP THINGS WITH GOOFY TENTACLES. BUT IT'S SO WEAK RIGHT NOW. D<

At least the Holy Moonlight Sword has nothing but 20%+ gems going on from dealing with Winter Lanterns.
