Notes Edit
- Arcane Comet can be seen flying from the champion using it even if there is no vision of them, possibly giving away their position.
- The impact indicator has a radius of 175 units, for reference.
- The comet will be disabled on death, but its cooldown will still be able to get reduced by ability hits.
- Arcane Comet can be blocked by
spell shields. - Arcane Comet is a
projectile and can be intercepted by 
Braum's 
Unbreakable, 
Samira's 
Blade Whirl, and 
Yasuo's 
Wind Wall. - Arcane Comet's cooldown is reduced by the ability that triggers it.
Strategy Edit
- Damaging abilities that apply a
slow make it difficult for the enemy to avoid the Arcane Comet.
- Hard crowd control abilities typically guarantee the Arcane Comet to hit.

Ability damage is an umbrella term for spell damage, area damage and persistent damage. It is a prerequisite for applying ability effects.
This classification should not be used except in cases where all three of the aforementioned types have a consistent output.
ChampionChampions are the player-controlled characters in League of Legends. Each champion possesses unique abilities and attributes.
Edge rangeEdge range is calculated from the edge of a source unit's hitbox to the edge of a target unit's hitbox.
- Edge range is mostly used for basic attacks; skill shots; and point-blank areas of effect (including auras).
- These become more effective against large champions, as the source gains more reach against them. This may be favorable or unfavorable: durable champions tend to be larger and thus easier to hit, and frail champions tend to be smaller and more difficult to hit.

Slow
movement speed for the duration. Slow percentages cannot reduce a target below 110 movement speed. Some slows will instead modify the target's movement speed to a static value, which may not be further reduced nor increased.Only the slow with the highest value is taken into movement speed calculations. All additional slows are ignored until the higher-valued slow wears off. The strength of slows may amplify or decay over their duration. Slows of the same debuff cannot stack and will instead refresh on each application unless otherwise stated.
