I was one of the first ppl to buy this expantion and yet im still stuck on the same part help PLZ!
soo im on the quest part were you have to meet the last asura guy in his lab (its the helping the asuras gathering the team part) I got gadd and that girl wit the robots golem things, so now i go to the lab i leave that city (the one were you can learn Polymok for the first time and you get you first peices and such) and i head south and go thro the potal to the explorable area where that guys lab is supossed to be, i see a green dot thing so i go to it.. i get there and i cant get near it.. its like on top of the wall is it supposed to be there?? is there a secret path? i looked for ages and didnt find anything...

mabey i didnt finish the gadd thing..? i did the dungeon and got to the end where he flips out and says "Who do i have to kill to get some help around here!" then it cut sceens me back to city, thats whats supposed to happen right??

well im gana check wiki agian thx for the help.

You just need to talk to the npc who comes with you on the quest. He makes a bridge.

Edit: his name is blimm, and he opens a 'secret entrance'

i'm assuming you're talking about the last part of "a little help" since you haven't given the name of the quest you're stuck on.
it can be difficult to find the path leading there. when you're close, there are a couple asuran corpses you can see by holding Alt. go toward them and renk's lab is right past them.
hope this helps.

Yeah the first time I went there I had to look around a bit too but there is a passage, almost like a tunnel in the lower area.
If you start from Rata Sum you go to the next area and when you come through the portal you go right and end up fightings some ferothraxes and then a raptor assassin boss. Then below from there in a sort of valley there is a small passage there on your right hand side...hopes that makes sense to you there.
