Mars' Spear exploit #19771

Ability name

Spear of Mars

Description

While doing Overwatch i encountered the following bug:

https://github.com/ValveSoftware/Dota2-Gameplay/assets/29153205/8d4e9fbb-df22-4366-a945-1bb7ad505392

As you can see Mars is in horizontal position, half in the ground and this seems to let him cast a really slow moving Spear when clicking on his own hitbox/portait (at 17:10 Mars starts testing the bug, at 17:35 the first slow Spear is cast), an enemy caught in it is stunned for a really long time if a displacement skill or item isn't used on it.

The bug involves getting sent out of map in some way and then blinking or tping back, this will make Mars become horizontal and let him use the slow Spear.

In the match id you can see Mars sending the flying neutral off map at 12:20, then Snapfire use his Aghs and eats Mars then tps to the creep at 14:40, and when Mars blinks back he goes back to the fountain and is horizontal 16:48. At 18.50 there's the first teamfight where the bug is used, and you can see both LC and SF getting hit by the spear being permastunned (until Mars knocks SF off using God's Rebuke).

I also found this video where the same bug is replicated using KotL Recall facet: https://youtu.be/IYeZ1ZmMD9k?t=300
