| Re: my pld Great Sword last WS quest in Bastok .... Hmm its been a while.
First, are you from Bastok? Because Gumbah is a NPC in the Rank missions there. If memory serves me correctly I had to finish some story line CSs before Gumbah would give me the trial weapon. check your qusst/mission log and see if there is anything with Gumbah you are currently working on.
Secondly, do you happen to have any other trial weapons open? You can only be working on one WS at a time, so if you have Savage Blade, Black Halo, or Retribution open currently he won't allow you to start Ground Strike.
Hope its one of the above solutions, and good luck with your WS.
