magic modding question

[Sombre]

That has been tried before in a couple of mods and works. 0 mapmove unit that you can summon which can then summon other units via domsummon, summon allies command, autosummon or by spells only it can cast.

The code for my Dogs of War mod includes a H6 unit who can summon unique commanders who then summon their individual troops. Paymaster - Captain - Troops. No gems involved, only high goldcosts to create upkeep.
