Pool Party Lissandra is my dream skin.
(This would obviously be her Legend skin but..)
Lissandra would wear a long, dark blue sun dress and a large black sun hat with a blue ribbon. Her ice crystals that she stands on and moves with would be replaced with a sand castle that would form towers as she moved.
Passive, when used would cause the ribbon to untie. When it readies, the ends of the ribbon would retie into a bow.
Q, would be a thrown, closed beach umbrella that would open if a target was hit to extend the range.
W, would be a poofing area of sand, if a champ was hit it would trigger a beach chair to snap on their legs for the root.
E, would pop up three standing surf-boards and send them sliding in a straight direction, tapping E again would cause her to tp.
R, would create a circle of sand. The sand castle at her feet would then grow to full size, covering her. Casting on an enemy would cause the sand circle to appear but instead of a castle, a port-a-potty would pop up and encase the champ.
Her backing animation would raise a small wooden shack around her with "Rentals" written over it. It'd have a surf board on one side, umbrella's and chairs on the other. Liss would walk up to the window/bar of the shack and put a shovel and pail on one side. She'd then pick up a rag and start cleaning the counter and humming happily as she backs.
