.. it does w/e u set the npc to do.
Most servers make rebirth chars get extra caves/kits/skills ect
well if you want that gna have to set it up that way.. it donesnt just auto happen lol.
Say if r/b was level 90 , u set level back to 50 (it would just go back to set base dc/sc/mc for that level and go up as it would b4, unless u change)
