How to turn regular green goblins into shamen etc?

[nevascared0]

Im puzzled and stuck with an army of basic goblins. When or how do the other types come about?

[Tolerant]

Mate high elf's which have evolution chance increase.
Or use goblinettes to create many at same time with lower chances of evolution.
Feed all of them with milk.
Wait for shaman.
Repeat with shamans to get more shamans and eventually - hobgoblin.

First time i got shaman from spamming common goblins with goblinettes (they give birth to MANY goblins per attempt)

Put high elf female with goblin, and goblin with goblinette. Eventually someone will evolve.

If you wont feed them with milk, evolution chance seems lower. So feed them until you get at least one of each type.

Mostly Accurate, Important tidbit "breast feeding"

[flannan]

And for hobgoblins, they have to be breastfed every time, not just to evolve them. If not fed properly, they don't grow to their full might, and become runty shamen instead.
On the positive side, it means you can build a single production line that outputs both kinds of goblins.
