Rebirth is going to be implemented into the servers progression. If you remember the original deathzot, how you had to acquire the apoc rune to get past the yeti in the snowy area. It will be similar to that in a way, but instead of getting a rune, you will have to rebirth instead.
An example: (and this is not the real numbers btw)
Level 1-1000
>Rebirth
Level 1-5000
>Rebirth
Level 1-∞
Well thats intresting i thought it was like level 25k rebirth too level 1 then re-level back up to rebirth again your way sounds intresting though.. all though i cant see what your tryin to say for the 3rd one.
