FFXII - Walkthrough - Old Archades
Alley of Low Whispers: Cutscene. There's an item seller here that sells Embroidered Tippets... which gives the equipped character Double EXP! I strongly recommend purchasing 3, as your party only ever consists of three EXP-earning people at any given time. Once that's done, go west.
You'll see you can't enter Archades... cutscene, you lose 1500 gil to employ Jules' services. Time to find some info from the Archadian Vulgars - whose names appear after speaking to them.
Speak to Beasley - he's slumped in a corner partway through Alley of Muted Sighs, talking about his lost bag of coin. Then, speak to Lucky Man, a guy talking to a Seeq near the entrance of Alley of Muted Sighs. New bag of coin, eh? Time to go back to Jules.
Jules instructs you to talk to Beasley, who's pissed about his lost bag of loot! Back to Jules, who's not where he was before, but sitting on a crate nearbye. Talk to him... the entrance to Archades is opened up!
