Zoe Ability (LoL): Spell Thief

Passive: Enemies drop spell shards when casting a summoner spell or using an active item. Specific minions also drop a spell shard when Zoe kills them. Zoe can pick up this shard to cast that ability once.

Passive: When Zoe casts this ability or any summoner spell, she gains 30 / 40 / 50 / 60 / 70% movement speed for 2 / 2.25 / 2.5 / 2.75 / 3 seconds and tosses 3 missiles at the target she attacked most recently. These missiles deal 25 / 35 / 45 / 55 / 65 (+13.3% of ability power) magic damage each.

Active: Cast the ability from a spell shard Zoe has picked up.
