Taniec Śmierci

Replace a summoner spell with A Dance with Death. A Dance with Death: Enter a contract with death for 6 seconds, opening a rift to the underworld beneath you and chaining you to it for the duration, during which you are also invulnerable and gain a minimum health threshold equal to 25 health. Over the first second, you become displacement immune and unable to act, and afterwards blink to the target location. For the remaining duration, you are inflicted with a health threshold equal to 100% – 1% (based on seconds elapsed) of your maximum health. If your current health is above the threshold at each interval, it is reduced to the maximum health ratio of the threshold. After the first second, if you score a takedown against a champion within 3 seconds of damaging them before the end of the duration, your contract is fulfilled and this effect ends. The health threshold is removed, you are healed for 250 – 1000 (based on level) (+ 10 per 1 lethality) (+ 10 per 1 flat magic penetration), you blink back to the rift's location, the rift closes, and A Dance with Death's current cooldown is reduced by 20 seconds. Otherwise, if the duration expires, you fail your contract and are dragged into the rift, where you are executed upon arrival. The health threshold cannot be modified nor exceeded by any means. The pull towards the rift is a forced displacement. While being pulled into the rift, the champion is rendered untargetable and unable to act.
