Torgrim is a very interesting hero, not an easy one, but when leveled up to 20, he starts reflecting every other spell.
And with dwarves, he only belongs in the Castle))) I don't see him as a main hero. IMHO, there are some "lucky heroes" and some "unlucky ones." For Druids, these are Alagar and Torgrim. Although they should be super heroes, it's always difficult to play with them. Alagar's specialty is "Ice Bolt," a second-level spell, but he doesn't always get water magic, and it's generally not a very effective spell. I still don't understand which magic works best on which creatures, and which units are strong against others. For example, swordsmen are very effective against flying creatures. This isn't mentioned anywhere, but I think there are some bonuses.
P.S. Sorry if this is off-topic.
