In first ruins you can't get back up the cliff unless you die/have porter/gate etc. I've always thought one way dungeons in exp zones were one of the stupidest things. It really screws melee's and hybrids as they're forced to eat a death or bring a porter to get them out. Maybe you could add an npc to tp you up and down, similar to the npc in thurg who tp's you below the bridge so you can get into crystal caverns.
