Elune's Arrow

Elune's Arrow

Fires an arrow to a location with deadly precision, dealing large damage and stunning the first unit it strikes. Stun duration increases based on how far the target is, ranging from 0.5 to 5 seconds.

Level 1 - Deals 90 damage.
Level 2 - Deals 180 damage.
Level 3 - Deals 270 damage.
Level 4 - Deals 360 damage.

Cooldown: 25 seconds.

Level 1 - 100 mana, 3000 cast range, 140 Hit AoE, 3000 Distance, 800 Vision Range, 857 Movement Speed.
Level 2 - 100 mana, 3000 cast range, 140 Hit AoE, 3000 Distance, 800 Vision Range, 857 Movement Speed.
Level 3 - 100 mana, 3000 cast range, 140 Hit AoE, 3000 Distance, 800 Vision Range, 857 Movement Speed.
Level 4 - 100 mana, 3000 cast range, 140 Hit AoE, 3000 Distance, 800 Vision Range, 857 Movement Speed.

Notes:
- The arrow does not hit allied units.
- For every 150 distance the arrow travels, the stun duration upon impact increases by 0.5 seconds. For example, an arrow that travels for 300 range stuns for 1 second, and an arrow that travels at least 1500 range stuns for 5 seconds (which is the maximum stun duration).
- The arrow has an effective movespeed of 837 units per second.
- The stun duration is determined by the distance between where Mirana fired the arrow and where the arrow hits its target. This means the stun duration is not based on the actual distance the arrow travels in some cases (if the arrow hits the map boundary and moves along it). This also means that firing the arrow and immediately moving backwards will not increase the stun duration.
- The stun is blocked by Linken's Sphere but the damage is still dealt.
- Invisible units will not be stunned, but will still take damage.
- Elune's Arrow deals Magical damage which is reduced by the target's Spell Resistance and is blocked by Spell Immunity.
- Elune's Arrow deals the damage before the stun, so it is fully evadable by Phase Shift.
- Elune's Arrow is regarded as one of the most powerful single target nukes when used by a skilled player. Apart from Pudge's Meat Hook, it is a non-ultimate instant single target nuke that does the most damage with a concurrent stun (Laser deals more damage, but has no stun). Also the fact that it goes through allies makes it very powerful in lanes, especially if you catch an opposing hero unawares. Together with Leap and Starfall, it gives Mirana a very powerful combination. If you find yourself getting targeted a lot by Mirana's Elune's Arrow, getting Linken's Sphere would be a smart idea, as it blocks the stun entirely.

Hey dotationary
I would just like to know:
Didn't the arrow have truesight once?
Banansnask

No it doesn't have any truesight.
It will deal damage to invisible unit, but not the stun nor vision to it.
