What makes him better than her? His attack mainly increases as he levels up, but that probably isn't very good either.
1) +2 attack from the start (an extra 10% damage).
2) For the first 10 levels, there's a 90% chance to improve combat skills rather than magical ones. Gundula only has 50%. And combat skills are more important both in the early stages of the game (where there's almost no magic, but many battles) and in the late stages (where there's too much "meat," and magic is mainly buffs and debuffs).
3) Better skill tree - it more often gives useful things like armor and tactics. Earth and air skills seem to be given equally (I don't remember offhand). And second-tier skills often give good ones (archery, passfight, artillery, leadership), while Gundula is more likely to be given some useless magical skill.
And Mass Prayer is a very distant prospect, besides, it may not even be given, and even if it is, it's not a fact that it will somehow help against Krag, who has already gained a significant lead in development. For example, at the beginning of the 2nd week, Krag feels much more confident in battles. With all the consequences that follow.
