+ next time, the movement speed of favorite slave units will be reduced to 4, and the tier 1 and tier 2 alternate upgrades will be nerfed. This should make things easier in this regard. The HP of units is balanced based on the calculation of "average HP sum for the level increase of creatures/creatures + the ratio to the health of creatures with the same level increases," so everything should be normal in this regard. I will be nerfing them little by little until they reach a state of being "annoying but not nightmarish." The damage is 40 per creature, as described in the ability property (it should be at least that).

Regarding ranged units. 1 ranged unit. The tier 4 alternate upgrade also serves as a ranged unit. Tier 5 and the Warlock hero himself. Based on the original Heroes factions, this toolkit is sufficient.
