[Champion Concept] Vjetar, the Aeromancer
Just go look up what an Aeromancer is, it's a wind mage.
Passive: Rush of Air- Every time that Vjetar uses an ability, he gains a 50% move speed increase.
Q: Ventus of Power- Vjetar expels wind from his body, dealing damage to all targets in a line, and leaving a trail of wind. If an enemy walks through this wind, they are slowed.
W: Power of the Wind- Every 10 seconds, Vjetar gains a [Mark of Wind]. These marks stack up to 5 times. Anytime an enemy champion is hit by one of Vjetar's abilities, it consumes all stacks, increasing the damage of that spell.
E: WIND! ASSIST ME!- Vjetar dashes to target area, hurting all enemies who were in the area where he left AND the area where he hits.
R:Wind is INFINITE- Vjetar consumes all [Mark of Wind] stacks on himself, and explodes, doing damage to all targets in a small area and knocking them back. If Vjetar kills a target using this ability, his [Mark of Wind] stacks are returned, and the mana is refunded.
