スペルスプリット

Upgrades one of your champion's abilities that has a missile, empowering the ability's missile to split in two over 0.25 seconds upon hitting an enemy, at maximum range, or when recast. Each of the split missiles fire perpendicularly in opposite directions and apply the same effects to enemies they hit. Subsequent missile hits from the same cast against the same enemy deal 30% damage. Recast can be used after 0.15 seconds of the initial cast.
