Skarner Ability (LoL): Crystal Spires

Skarner's presence causes crystals to spawn in set locations around the map. Crystals can be captured by either team by standing on top of them. Capturing a crystal prevents them from being captured by the opposing team for 15 seconds.

While within range of a Crystal Spire, Skarner gains 70-120 Movement Speed and 43-160% Attack Speed, while restoring 2% of his maximum Mana every second. Spire radius is 1600.
