Dahn-mag? I disagree. I believe that all Dark Elf heroes are battlemages because their attack, as well as their magic, increases:)
The most battlemage-like heroes are Iranna, Vainshan, Kifra, Sorgall, and Erin. The others are much more mages than fighters.
Developing a Warlock often leads to increased attack and logistics; it would be a sin not to take advantage of that...
I'll show an example with Iranna:
1. Education
2. Chaos
3. Attack
4. Luck
5. Logistics
It won't be possible to create a warrior-mage for one simple reason: even with low magic, a Warlock casts spells instead of shooting...
