I confirm, I leveled Marbas and Grok equally; both had Light, but Marbas was stubbornly not given Devourer while Fire consumed all the mana, so I had to switch to Grok. Somewhere around level 13, Grok had Expert Light, then I tried to get any mass spells but they were stubbornly not given (the first offer came only at level 33)). I entered the enemy's treasure zone for the 3rd time, but all the Dragon Utopias were positioned unsuccessfully — our paths crossed and Vitya entered; Grok didn't have time to devour much. Then the hit wounds from Vitya were painful — and I messed up myself, I should have fought to the end when the ATB aligned favorably. Thanks for the game
