It has no real means of regeneration. However it's limbs are mainly just normal steel. A skilled armour-smith could repair any damage done to the non-magical parts of Buttercup's body.

The blade can probably be repaired, but it just spent about 200 years wandering the wild wanting nothing more than to count flowers. So it might be repaired later on in the rp, when the need for flaming swords becomes more apparent.

Also, Buttercup spent 200 years memorizing flower names. If it doesn't know the name of a flower, it just makes up a name for that kind of flower.
