I was in the big ben and i summoned a talos using a treasure card. The minion never got attacked and I was pounded. I believe KI should make the monsters attack the minions a bit too. because in the other worlds the monsters would try to eliminate the minion immediately.
Talos does not Taunt and because it uses higher level spells, takes a lot longer to gain aggro. If you want enemies to attack your minion, your better off using a water elemental or minotaur.
