i just edited it a bit and added some pictures so it might be easier to follow the steps.. (quoting him) xD they need picture's to understand.....
Some ppl get stuck at rb4 quests coz they cant get the items needed in spring town due to the fact they cant talk with the npc's and they dont know how to do the language barrier quest...
First thing u have to do is buy some tickets at ticket seller in npc argent city for icicle city, spring town, and icespire haven
Then u teleport to icicle city to and go to language barrier item exchange Npc (1333,545) and click on it and then click Obtain.. she will give u the 4 items needed for the quest for 20M
thirth step is teleport to Spring town and click on spring town teleporter and click on the language barrier quest
Accept the quest and u will see u need to go back to argent city( 2276.2769 ) and talk to the sweet old lady Granny beldi
Fourth step for language barrier you'll need to go to icicle city again to find waitress babara (1350,530)She will give u next quest item for some cash wich is Omni antidote presrciption Click it 2 times wich will activate last part of the quest
Final Step of language barrier is bring the ingredients for language quest to master kerra in icespire haven (remember the tickets u bought earlier) use ticket to icespire haven and go to master kerra (2665,653) and accept final part of the quest she will take the LB quest ingredients. 50,000 gold and give u some items in return and Hooray quest is Finished !!!!!!!!!!!!!!!
