"Necropolis" - changes to creatures of levels 6-7.

Why Ug-Tho? Does Thunderlord have a very powerful storm? Or are you already thinking about how to implement him as a caster?

In the original, many of Ug-Tho's abilities were present, including the war cry, storm, and titan's lightning.
The damage from the war cry should be many times higher than the damage from a regular attack because it is performed from a distance. Only then will people fear him.

I'll repeat - Deadly Strike used to be available to the player once in a blue moon, and it was still powerful (here's a bonus for you -20 damage out of 40 Black Dragons).

The example is not convincing. 1 Sorceress can also apply a slow effect to 1000 Red Dragons, and with a guarantee, so what? Is that overpowered?
