You were always able to breath in water. Now that you are an adventurer or maybe a bit before you learned that you could breath air as well. I wonder what you can get up to now that you are able to go on land too!

You know the drill, +2 to one and +1 to another or +1 to three.

Axolotl's are able to regenerate lost limbs and other body parts, this also get's augmented because you are an adventurer. 

When you receive healing from any source gain 1 Hp more.

During a long rest you can regenerate up to one limb or up to 15% of your body during a long rest if before the long rest you had more than half your hit points and no levels of exhaustion.

You gain the following spells: Mage Hand, Find Familiar

These spells have the following modifications.

Your Mage Hand can always carry you at half your movement speed and it takes an action or bonus action to move on your turn. If you are not safely on the ground when the mage hand's duration expires It slowly starts to lower you harmlessly to the ground as if under the effects of feather fall. 

Find Familiar can only be used as a ritual and can be cast using one of your limbs as the component materials. The spell can also be used to summon an exact copy of you. This copy can act like you but can not speak and has the same stats as a pseudodragon. And equipment the copy has are strictly non-magical and disappear when the copy disappears for any reaosn.
