The idea is certainly excellent! I'll be looking forward to the release of this add-on.
In the meantime, I would like to know if it is possible in the add-on, and in general in the third installment, to have three types of each creature, as was done in the fifth installment, version 3.0? (That is, to add a third upgrade to them. For example, Goblin, Master Goblin, Santa Goblin, etc.)
