Heroes 5.5 WarGame Edition - Tactical Edition.

That's how golems should be: 20-50 damage.

Yes, golems in this mod are powerful damage dealers, not those weaklings they are in the original game (they couldn't survive, penetrate armor, or move properly). If you stand in their way, you'll lose a lot of health, that's how they work here.

But their actual damage is still lower than stated due to their low base attack. For example, against dragons, it's 4-5 times lower (nevertheless, 15-20 golems can take down 1 dragon in one hit).
