Rell Ability (LoL): Attract and Repel

Rell forms a tether between her and the ally bound by Attract and Repel, which is disabled while the remaining cooldown is greater than 2.5 seconds. While the tether persists, the ally gains 10% bonus armor and bonus magic resistance.

ACTIVE: Rell binds herself and the allied champion nearest to the cursor with Attract and Repel. Rell can then recast while the tether persists.

RECAST: Rell erupts the tether to deal 80 / 120 / 160 / 200 / 240 (+30% of ability power) magic damage to all enemies between and around her and the bound ally, stunning affected enemies for half a second.

Rell can self-target to dispel the current bind if she has not casted an ability nor taken damage from or attacked enemy champions within the last 3 seconds. Only one ally can be bound at a time, and selecting a new ally overrides the previous bind.
Attract and Repel will incur a 2.75-second cooldown with no cost if Rell binds to an ally and a 1-second cooldown with no cost if she self-targets.
