New Champion Idea that uses 4 elements in his arsenal

I don't want to go into specific stats or Lore. Just the abilities and mechanics. I want the champion to be a top laner and hard to play like Riven.

Abilities:

Passive: Your abilities gain special effects based on your current element.

Q: Your next basic attack deals X amount of damage

• Auto attack reset
• no cast time Fire: Deals more damage Earth: very short stun Water: Heals for X% of damage dealt Wind: Slows the target for X% for X seconds:

W: Does a small bit of damage in a circular area around you.

• small cast time Fire: deals more damage Earth: creates small walls at the edges of the circle(like Jarvan IV or Yorick) for 2 seconds.
• if the enemy is standing where the wall comes up, they get pushed to closest side of the wall and get stunned for 0.5 seconds Water: heals for X% of damage dealt for each champion hit Wind: knocksback enemies

E: Dash in target direction.

• range: 450
• no cast time Fire: deals damage Earth: grants a shield Water: Lowers the cooldown of E by X Wind: grants a small burst of movement speed

R: Passive: gain stats based on your current element(skill points:(0->X-->2X-->3X)) Fire: AD Earth: armor + magic resist Water: lifesteal Wind: movement speed

Active: Change your element to X:

• Changes the element in order everytime you press R(for example: Fire->Mountain->Ocean->Wind->Fire...)
• no cooldown
• no cast time
• does NOT allow you to reset auto attack
• 4 skill points in total, 1 is automatically unlocked
