Mirage archer.
Some bex and mark_ggg posts to help clarify wtf this is.
"The Mirage Archer support causes supported bow skills to create a Mirage floating above your head when the skill is used. This mirage will use the supported skill with reduced attack speed, acting like a ghostly turret that will attack your enemies even while you move around. Every time you use the supported bow skill, it refreshes the Mirage Archer's duration
There's a limit of one Mirage Archer. So one will replace the other if you use skills in sequence.
It triggers when you actually use the skill. You can't spawn it without hitting an enemy with the skill.
It's like a minion or totem.
It would curse the target but the Mirage Archer can't give you charges or on-hit benefits.
It won't work with Ranged Attack Totem or Siege Ballista yet, but we hope to have it work in future, if it doesn't break everything. It currently causes problems because of the Mirage Archer limit of one.
It cannot support Minion skills.
You only need to hit enemies to summon the Mirage Archer, not damage them, so you can still do that with AB. The Archer is not you, so can still deal damage.
No, for the same reasons it doesn't when a ranged attack totem gets the kill - it doesn't have the equipped bow and any of it's socketed skills to trigger."
so...
its a JoJo referance.
it is a totem basically. But, might not have the totem tag. its hard to say. mechanically it is. it does not use your bow, it does not count as your damage, for EE, frenzy charges, etc.
It is summoned ON HIT. which is a bit dissappointing imho. not as great for coh as I would like. depends on duration I suppose.

"Unfortunately, the last remaining support gem won't be revealed until after 3.1.0 It won't be in at release but it will be introduced soon thereafter. We're extremely sorry about the delay."
