Character concept

I don't have any skill on making a character but i was thinking of a idea that anyone can try to use i was thinking it of a elemental archer who has the first abilitys toggles so they add a effect to the arrows each will take a more amount of mana per ability level and every toggle will have different amount of mana i was already thinking of 2 ablilitys feel free to use these ideas it just a thing i wanted to say

earth arrows it leaches health from the enemy and a water arrow for slowing and let called true shot that does true damage i hope some one takes up this idea if u want to use it and change things up u can.
