When turning around to cast Dragon Tail while having the Kindred of the Iron Dragon equipped, one of the particle effects appears off-set to the sides, rotating along with Dragon Knight.

It looks like there is one effect bound to the caster, but is located so that it's on the target (its position is off set based on where the target is). But since it's a particle on the caster, it moves along with the caster, so instead of following the target, it follows the caster.
