Maokai rework idea

I'm just full of ideas today

Maokai

Maokai no longer has mana and now has 'vengence' (name placeholder)

Passive: Maokai builds vengence every time he or a sapling takes damage. Maokai also gains venegence every time a spell is cast around maokai. The more vengence Maokai has he Grant's himself increased damage reduction. Once vengence is full maokais gains empowed spells and his next basic attack after casting an empowered spell deals additional magic damage and heals maokai.

Q: same as live. Empowered, Maokai slams the ground and deals damage and a slow in an aoe around him, cooldown is immediately refunded.

W: same as live. Empowered, Maokai gains additional range and increases damage.

E: Similar to live: saplings can now take damage, it takes 2 hits to kill a small sapling and 3 hits for a large sapling. Sappling attack slightly faster. Empowered, Maokai tosses 2 large saplings instead.

R: Same as live.
