Temporary Game Mode Idea: The Singularity Boss Battle
Essentially, this would be a game mode where a team of 5 (most likely Zed, Yasuo, Teemo, Vayne, and Master Yi) fights The Singularity (pictured, a fusion between all five of those champions), who is either player-controlled or AI-controlled. Might take place on Crystal Scar after it's removed. I'm not entirely sure the requirements for victory for either side (certainly other things would have to be happening in the match besides teamfights between The Singularity and the players, because that would probably just get boring if that was all it was), but I have thought up a skillset for The Singularity. Each ability lists what abilities it is based on, as each ability The Singularity has is a fusion of several other abilities from the champions it is comprised of. Numbers are, of course, intentionally left out, so that things can be changed and fine-tuned by someone smarter than me.
The Singularity (One with the Rift)
Passive: Way of the Hunter/One with the Rift When standing still, The Singularity becomes invisible. Shadows are also invisible, because they are standing still. When moving towards a nearby visible enemy champion, The Singularity gains movement speed and a shield. The Singularity also heals and takes reduced damage while invisible. (Camouflage) (Meditate) (Way of the Wanderer) (Night Hunter)
Q: Shadow Rush Dash forward and become invisible. (Heal faster while invisible from Shadow Rush?) Leaves behind a shadow (you can reactivate the ability to swap places with it), and also leaves behind a mushroom trap that instantly stealths and arms. The first person to step on it takes damage over time and is slowed, but only them; it is single-target. For a while after stepping on the trap, they are marked, and The Singularity's next autoattack directed towards them does bonus true damage. (Tumble) (Camouflage/Final Hour) (Living Shadow) (Noxious Trap) (Wuju Style)
W: Shadow Tempest Unleashes a whirlwind that destroys all projectiles it collides with. All shadows will throw the tornado as well. This whirlwind knocks up all enemies hit. Additionally, Shadow Tempest can be used during Sweeping Strike to change the area of effect to a circle around The Singularity. This version of Shadow Tempest also causes active shadows to spin rather than throw a whirlwind. Shadows will slow targets affected by their slash (after the knockup has ended, if they knock up those they hit). Mimicked slashes that hit targets affected by the primary slash enhance the slow, but deal no additional damage. However, hitting the same target with more than one slash causes spinning blades to radiate from The Singularity in all directions. (Wind Wall) (Living Shadow) (Steel Tempest) (Shadow Slash) (Razor Shuriken)
E: Sweeping Strike Dash to the target, becoming invulnerable for a short period (but still able to use abilities) and slicing nearby targets with poisoned blades, dealing initial damage and damage over time. Whenever you dash, you acquire a stack of Legion's Might. Each stack of Legion's Might causes the poison applied by your next dash to do extra damage. You can have up to 2 (or 5, because 5 champions the singularity is made of?) stacks of Legion's Might. (Steel Tempest) (Sweeping Blade) (Alpha Strike) (Toxic Shot)
R: There Can Only Be One/Last Hour Blink to the nearest visible airborne enemy champion to the cursor. Upon arriving, suspend all nearby airborne enemies, ghosts (ignores unit collision) for 3 seconds, mark them for death, blind them, spawn a shadow at the cast location, reset the cooldown of Shadow Tempest and deal physical damage. Afterwards, ignore some of each affected enemy's armor, and gain additional attack damage, attack speed, and movement speed. In addition, attack twice every few auto attacks, as well as deal maximum health as true damage with every few auto attacks, deal a percentage of maximum health as bonus magic damage to targets low on health, and become immune to slows for a while. (Last Breath) (Death Mark) (Highlander) (Final Hour) (Double Strike) (Silver Bolts) (Blinding Dart) (Contempt for the Weak) (Wuju Style) (Move Quick)
