Zarnathiss generates 1 star fragment every 15 seconds and can store up to 3 / 4 / 5 fragments at one time. When he casts a spell, one fragment is consumed for extra effects. Star fragments are generated twice as fast when out of combat.
COST: 50 / 60 / 70 / 80 / 90 mana
COOLDOWN: 14 / 13 / 12 / 11 / 10

Mana Gain: 20 / 30 / 40 / 50 / 60

Zarnathiss channels for 0.5 second, then leaps into the air, becoming untargetable. After 0.5 seconds, he crashes into the target area in a blaze of energy, dealing magic damage to all opponents within a 1500-radius and stunning them for 2 seconds.
Damage: 400 / 700 / 1000 (+150% AP)
I made Zarnathiss intentionally overpowered just for fun. Please don't give me any suggestions for balance.
