This champion is work-in-progress. The core "feel" to the champion I want to achieve is similar to Clank's missions in Ratchet and Clank: Crack In Time, where Clank has to create holograms the repeat his previous actions. I'm struggling to create this in an multiplayer environment (you can't rewind, per se)... but I'm working on it.

Note that "project" is the verb "to project" (i.e. projectors projects images onto surfaces). It is not the noun "project" (e.g. a school project or a housing project).
Patch Unknown
Tactical Stealth
(Innate): If Quantum has no active holograms, Quantum will become stealthed for 1.75 seconds upon using an ability.

Ability Description Leveling up
Project: Assault
(Active): Quantum places a mark on his target, revealing them for 3.5 seconds. Quantum then projects a holographic copy of himself that will follow and attack the marked target mercilessly until the mark expires.

The hologram takes true damage from all sources, and has a modified attack damage.

  • Cost: 80 mana
  • Range: 650

Cooldown: 12 / 11 / 10 / 9 / 8 seconds

Attack Damage: 20 / 45 / 70 / 95 / 120 (+0.5 per bonus attack damage)

Project: Stasis
(Active): Quantum enters a channeling state for several seconds, projecting and assuming control of a holographic copy of himself.

While channeling, Quantum becomes intangible and cannot be targeted by minions.

Quantum can reactivate this skill to end the effect early.

  • Cooldown: 14 seconds
  • Cost: 50 mana

Duration: 3 / 3.75 / 4.5 / 5.25 / 6 seconds

Project: Recon
(Active): Quantum projects a holographic copy of himself that stands idle at the target locations for 3 seconds.

Upon decommission, the hologram releases a discharge that deals magic damage plus 30% further damage over the next 3 seconds to surrounding enemies. While the hologram remains active, Quantum can reactive this ability to trade places with the hologram. Quantum can do this once. The hologram takes true damage from all sources.

  • Cost: 80 mana
  • Range: 700

Cooldown: 20 / 18 / 16 / 14 / 12 seconds

Magic Damage: 80 / 120 / 160 / 200 / 240 (+0.7 per ability power)

Damage Over Time: 24 / 36 / 48 / 60 / 72 (+0.21 per ability power)

(First Cast): Quantum begins drawing in power, increasing the damage of this ability while rapidly draining mana.

(Second Cast): Quantum unleashes a surge of power, emitting an electromagnetic shockwave that deals magic damage to all enemies caught as it spreads across the entirety of the field. The damage diminishes over time down to a minimum. Project: Overload deals 25% less damage to minions and monsters.

While preparing to fire, Quantum cannot autoattack or use abilities, and his movement speed is slowed by 20%. After 3 seconds, running out of mana, or being disrupted, Project: Overload will fire automatically. If Quantum is disrupted, he will only deal the minimum damage.

  • Cost: 80 mana

Cooldown: 120 / 100 / 80 seconds

Upkeep Cost: 30 / 40 / 50 mana per half second

Total Cost (including activation): 260 / 320 / 380 mana

Minimum Damage: 200 / 400 / 600 (+1.0 per ability power)

Maximum Damage: 350 / 700 / 1050 (+1.75 per ability power)

Minimum Diminished: 60 / 120 / 180 (+0.30 per ability power)

While Quantum has an active hologram, he resembles them (rather than Shaco, whose clone resembles him). He becomes translucent, and tinted a different color. Holograms do not have unit colision, and will walk out of Quantum when spawned.

Combining his Tactical Stealth and Project: Recon, Quantum can trick enemies into thinking he's using Project: Stasis; allowing him an opportunity to feign Assault and attack his enemies personally.

The point of Stasis is positioning. You can sit in a brush, and walk into the lane using Stasis. You can then cast Recon to place a blink-point that would otherwise be miles out of lane. In an ideal circumstance, they would go on your hologram (maybe even kill it), then you blink to your Recon from the brush where you were sat safely the entire time.
