(Question) Are souls equivilent to chc slots?
Yes. Your character dies -- and then the soul passes on and you can spark it into a new character.
(Question) Can I have 3 different chc on 3 different servers? Of course only one can be played at a time.
We currently don't know how many can be played at a time. But it has been confirmed that we can buy soul packs that are locked to other specific servers (your first 3 souls on your account that come with your package will be locked to the server you pick during server selection which is coming up soon)
(Question) Say I make a Brudvir and dont like that chc can I delete it and still have 3 souls available? Or is it one chc per Spark period? If thats the case can I delete that one chc and start over whenever I want till my spark of life runs out? Hope this makes sense.
You can't delete characters, you can try to kill it off -- but then you'd require another spark to spawn into a new character, so you'd be wasting a spark. I think that answers all of your questions if you have more feel free to ask!
