Heroes in Heroes of Might and Magic V: graphics, biographies, skills...

I wouldn't say it's a very good ability. Just an immediate summon of 30% of creatures? Not that strong. But lowering the morale of all enemies! That's great! Or am I missing something?

Actually, it's 40%, plus 30% of our summoned creatures, doubled in quantity.
And if the hero is a gating specialist (+1% per level, I think)... it turns out to be quite effective...
