Battle for Wesnoth

Tactics are certainly a good thing, but as in a roguelike, percentages can ruin everything, but these are minor issues. I'm almost done with the first campaign, I think I'm on the second to last mission. Thanks to all this, I've managed to level up my support group quite well, and they're tearing everything apart. Unless I'm really unlucky, there's not much to spend money on after the initial purchase, so I guess I'm ready to move on to the next stage. By the way, Ples, why is the Paladin more effective against undead than his counterpart of the same tier? Four units of healing don't really make a difference, while the extra damage and fifteen or twenty hit points are very helpful. Or were you talking about these upgraded Knights in general?
