Invisible ally?

Once I was summoned by someone and we went through Undead Burg. It looked like it was just me and him. Then I noticed some enamies dying without being hit by me or the host.

Later a friend of mine noticed the same thing.

Is it possible for a host to summon 2 helpers that can't see each other :?:

Yeah, any given phantom can be invisible to any other given phantom. I've seen white phantoms as invisible while darkwraithing, fellow Forest hunters as invisible as a forest hunter, and darkwraiths invisible as a Forest hunter.

The invisible phantom thing happens a lot, especially when gravelording. For me at least, every third and fourth phantom that invaded me couldn't see the other! Was a bit frustrating as a gravelord in the forest to say the least.

I think the problem stems from the phantoms being able to connect to the host but unable to connect to each other.
