I know this has probably been covered ad nauseum, but I'd like someone to cover it again.  I've been playing a lot of Advent lately, and eventually get high level motherships with the level 6 ability ("reincarnation" or whatever you call it).  I have 2 questions.

1) When this ability is on autocast, it will continuously cast if there are other capships (mine) around.  This is even if there is no battle going on, or nothing happening.  What is it doing?  I theorized that it was storing the "souls" of the capships, and that I needed to let it do that, otherwise the final ability wouldn't work when I needed it to.  However, it could be that I'm just wasting a ton of antimatter letting it sit there and autocast.  I mean, is one "soul storage" enough per cap?  What's going on?  WHAT IS IT DOING WHEN IT CASTS ON LIVING CAPS OVER AND OVER AGAIN?  Also, is it a good policy to just keep it on autocast?

2) How do you "reincarnate" a dead cap using the ability?  I haven't had the occasion to use the ability yet, so I don't know.

Thanks.
