As a summoner, you'll want to get THM to 26 asap. swiftcast is so important. You may also wish to level archer to 34, this gives two abilities that really are important and a couple less important; Raging Strikes (is learned by 15, and increases all outgoing damage by %) and Quelling Strikes (at 34, which reduces the amount of emnity you generate) Hawk's Eye is important at end game but not much else, as it guarantees attacks land on a target and ups Dex by % (good to help dodge maybe? mostly just for the hit lands though)
