I have a suggestion for a monster. Kobalds like from D&D. Theyre basically worse goblins but when they evolve they become a dragon wyrmling. Which is basically a weak baby dragon its level 1 in D&D btw. Then it would become a young dragon and stuff like that.

I think the fanged lizard would be able to become a dragon eventually as well, if I am understanding the systems right; either through transformation or variance.

I like the idea of a Kobald though, if we make it a stealth class. The rogue to the Goblin's fighter.

If I can suggest another creature, it would be a Spriggan or something similar. A kind of support class that does either crowd control, removed debuffs or both; it could use vines to entangle enemies and have a secondary kind of healing that removes poison/stun/etc but doesn't heal injuries.
