So for the last bit, I've been struggling to determine a good body modification for Tier 2 on a slime; I've got a few questions with that in mind!

1) Given the nature of slimes, I've hesitated on standard options because I assumed it would mean the loss of the Puddle Ability. If Loki were to obtain a solid modification, such as horns or similar, would that in fact be the case?

2) Another idea was to change the physical properties of the slime itself; such as becoming like magma, or some other non-typical substance for the speices. Would that be an acceptable modification?
