Finally finished my play trough:
thoughts:
At first the AI was really kicking my ass, but in the end my level 6 characters beat alexander and the void worm (2 levels up). What changed? I figured out that the AI will always try to attack/win. I on the other hand was running and guiding them to a choke point (playing for tie, (not losing)). Once you block a path for them to rush you they scatter and attack you one by one.
In the fight with Alexander I triggered the battle and then teleported away. I let them come to me and with some fire en poison 3 enemies did not move, 2 walked trough the fire, 1 decided to take the long detour. If they joined together to attack it would be a lot harder.
No sourcepools -> no way to get braccus rex helmet (I released all those poor souls)
