so now the wizard (presumably the mage best suited to attack spells) can finally bind attack spells to a familiar, previously only for force master's thought spore could do that.
you are right that most wizards will insta add this to there book (when i read the name i was already thinking what 2 points i could drop). air wizards tend to go only lightning attacks due to there lightning ring, so this tower would be a nice addition because it can cast the wind attacks which will cost you the same.
or imagine running a fire wizard with 5+ fire resistance and sitting in the tower while it constantly playing the best hits of Johnny Cash (Ring of fire) best counter for swarms.
now i just have to keep annoying the Australian store to know when this set it getting here.
