Mechanic: Orbital

The Orbital skill fires a special type of projectile that will orbit around the target and can also act as an Aura. Like the projectile, it will trigger other skills on anyone that is hit by it during its orbit.
Much like projectile, it's great for creating complex skills, such as a fire shield, and is a very complex skill to master.

Attributes

Special Notes

For the onStart Skill: onStart skills work in a special way - any buff or "special effect" mechanics fired by onStart that have a duration (such as ParticleTornado) will attach to the projectile for their duration, which allows for some interesting effects.

For the onTick Skill: using the @origin targeter will cause any skills or effects to target the projectile's location. This is the intended way to configure how the projectile looks.

For the onHit Skill: Any targets the projectile hits are passed to the skill inherently. Any targeters you put in the onHit skill will override these and cause your skill to likely not work as you intend.

For the onEnd Skill: Special effects for the projectile's end also use @origin. Also, If you want entities near the end-point of the projectile to be hit in a certain way (such as a final large fireball explosion) you can use the @PlayersNearOrigin{r=[radius]} targeter.

Examples

This example puts an icy-looking orbital shield around the mob when it is hit sometimes, that will last for 10 seconds or until it is triggered once:
