1st time poster, hope its worthy. So for Getting around With Shadow Pan you need to do all 9 NPCs x15 quests, which will take you 27 days if you are lucky. What you do though instead is just sit and afk with the quests in your log but NOT pickin up an NPC and sit at the quest giver. Eventually over time people will turn in quests directly if they are doing the solo achievement. This will get you credit with all 3 of the NPC of that day and thus clear them x3 x15 so you afk getting 45 quests (towards tthe achievment) done by doing nothing.
Cheers
