-Does the skill only work on either the X and the Y axis?
No, it targets directly behind you, so if you’re moving around with controller or mouse it will adapt to those angles.
-does the AOE go in a cone or a straight line?
Straight Line
-what is the range of the skill?
About double auto attack range, pretty much your entire screen length if you’re on a 1920x1080 resolution
-how about weaving no cd skills in between while retreating, does it prevent retreat shot from shooting?
If it roots you down it will prevent retreat shot from shooting. If it doesnt then it won’t
-How about diagonal and running in circles, zigzagging while running away with target lock?
Best I found is just running into a wall. If you have a large group of melee mobs chasing after you, running in a circle is pretty good. If you’re fighting a boss with a really large hit box but a small collision size, you can run in a tight circle around the boss and hit all of your retreat shots.
-If I am currently overburdened by carrying capacity will the skill allow to retreat slower or at the same speed?
Yes, but since the number of retreat shot attacks scale with movement speed, you’ll only shoot out about 15 shots as opposed to 30 on normal speed (45+ with chronomancer haste, I think it scales close to 1:1 with movement speed)
-Lets say I am using xbow/arde in weapon set 1 and another xbow/pistol on set 2 will I be able to use retreat shot without swaping from xbow/arde?
does jumping break the buff?
swapping will break the buff. However, I’ve found that retreat shot works with every weapon, if you use it with a 2h bow on flying mobs your retreat shot does 2x as much damage.
