Circle of Death - Skill Mechanic

[Nudl]

I haven’t tried the game yet so there might be a mechanic like this, but this is like a wishlist skill mechanic from PoE. The idea is that it works like Shock Nova from PoE where it hurts enemies in in a ring around you. Except i want the skill to not deal any damage unless the the enemies intersect that ring. This is what i feel like made Shock Nova dissatisfying in PoE, because it still hit units in a radius and was very forgiving. So you basicly just spam Shock Nova with no regard for the ring. Which i feel is missing the concept or idea of the skill, which is to force you into a risky mid-range and constantly space against your enemy.

Now if you want to make it more original:
-It’s a pop once and it will last 6 seconds before decaying. (You can use other skills in the meantime)
-It’s constantly active, but you have a ball spinning around the circumference and that’s the only part that deals damage. (Now you have to rotate yourself around the boss/mob
-It’s a channeling skill, that adds duration per channeled second (think PoE Winter Orb).

This is my ideal way of implementing this mechanic, but it might not fit your skill framework.
-You can “channel” cast it while walking and you must constantly keep doing it to keep the skill active, but every time you do your movement slows drastically. The movement speed is tapering too.

So there is no mechanic like this i can think of in the game currently.

There is one thing that is kinda similar. But not entirely.

Devouring Orb from Void Knight, can be speced, so it Orbits you and dealing impact dmg, when hitting an enemy. You can also alter the distance, at which the orb orbits you.

You can have multiple of those active at the same time and you you as the player are in control a little bit, while the orbs areorbiting you.

This is not the same thing as you suggested, but it defintiely would require some skill and “aim”
