Ah, yes, I forgot about the Orcs. Yes. Against an Orc, you need to use summoning. How do you deal with Darkness? Only if you are sure you can learn powerful Darkness spells. And that doesn't always happen. In general, of course, a Warlock has little chance against an Orc in a long game. Against an Academy mage, there are chances, even with my build. Kifrah with Vengeance deals good damage and has a chance to inflict luck. But I agree that summoning is definitely more useful than Chaos in a long game.
