there are two (at least) bugs related to the dominate spell.
1. units that are dominated at the end of the battle remain in your army after the battle, and the spell doesn't wear off in 5 seconds if the unit fights in a second battle.
2. the ultimate villian is vulnerable to dominate.
the combined effect of this is that it is trivial to create an invincible army of ultimate villians to defeat whoever you would like to defeat.
This is a great game, It is extremely obvious how much time and effort went into this (and not just from the three year delay). The MARDEK series is one of the funniest games I have ever played. Legion is by far the most hilarious thing ever. I cannot wait till MARDEK 4! 5/5 without a doubt
