Back as a tree

Intro you were killed by a poisonous snake in your past life and now you wake up and are now a magical tree, your bark is blue, your leaves are light blue and you have long purple vines with round dark blue tips. in the middle of your body is a green magical floating sphere with a face on it, that is your head. you start as level one but you can gain points by killing things,the stronger it is the more points (example: killing a level 1 rabbit will give you about 1.5 points while killing a wolf will give about 7.0 points). the more points you gain the more you can level up.
