As it is, Spiritreaver is heavily reliant on a single element (Ice), probably more than the other relevant head/frame combos. Also, Magic Accuracy has typically been associated with either Water (Leviathan's Favor, ACP Sapphire Earring/Ring augments, Leviathan Ring +1) or Darkness (GEO, Fenrir Ring, Tenebral Crush BLU trait). I think the Tranquilizer attachments should be changed to one of those two elements.
