Yes, I saw those new settings, and except for Difficulty, I'm using the highest setting in each one. I'm playing on Difficulty 2.5 with 4 opponents because the map is bigger than standard (you said Setting 5 or 6 would be a real challenge, however I like to build up my heroes with heaps of quests and monsters, and collect all my Quest and Event heroes, plus the Unlikely Heroes modmod I made, with No Experience Split and eventually go against the fully built up opponents, but so far the Spell of Making keeps coming up ). In my latest game, I used the Ranger's "Web" ability to fix 8 out of 9 enemies in one battle I had, and my Bacco the Beggar with Enzo's Knife and almost full Champion Armor (which I bought from them before I DOWed, heheh) to mostly avoid the big-hitting Hammer units. It will be even better when Enzo's Knife stacks properly! And the one time I got hit by a 3 or 6 members remaining hammer unit, I took 70 damage but still had 20 remaining. And I had Rachel and other healers to heal Bacco up throughout. I won the battle without any losses apart from my unit that the Ranger (Mouse from Unlikely Heroes I made into a Ranger) summons at the start of every battle. Even my Greater Demonshrill unit (5 members) made it through without dying.
Just wondering, do you have any idea why the Spell of Making is being cast in my games? AFAIK there is no mod that would enable the Spell of Making if you have the pre-game option switched off.
