Honestly haven't decided on that yet, because I planned for evolved monsters to have offspring of the same species. For instance, two goblins that evolve into hobgoblins, and then into orcs, and then have a child would have an orc child. But would an orc child still be more powerful than an adult goblin due to evolution? Is it born with the same skill build-up of raw stats or other things? I'm still trying to figure some things out and this is one of them. As of right now, though, I'm leaning towards saying that levels won't reset, or at the least you'll have separate levels for each form, and then a total level that's a combination of them.
