The notification scrawling across my core was very expected and very welcome.

Your creature, a Burrowing Rat, is undergoing evolution!

Please select your desired path.

Ratking (Uncommon): Commander of the lesser rats, it uses its long and powerful tail to bind them to its will, forcing all those in the vicinity to serve it with reckless abandon whether their lives are kept or lost.

Arcane Ratkin (Rare): Harnessing various gems, this creature uses its growing skills to command mana as it pleases, choosing from its collection of jewels for which it wants to use at any given moment. Though it has no specializations, it can use any attuned mana-gem, given they are full.

Mage Ratkin (Rare): Unlike its arcane brethren, this creature chooses a specialization in only one branch of mana, and can now generate their own attuned mana to use as they see fit. As they study and train, their power can grow to be reminiscent of a true mage.
