You guys probably have this already, but in case you dont, i will share it anyway. Again, not seeking membership, plan on buying it.
Step 1.
Create another Content ID and make a character in Windurst. Take him to the Windurst Port Mog house and switch to your main character.
Step 2.
Go to your main account and send your character in Windurst 1 rarab tail and 4 wild onions.
Step 3.
Get on windy account, collect the wild onions and rarab tail, and take them to Kohlo-Lokolo behind the Wharehouse in the Port Windurst district. Watch the cutscene, then trade him a rarab tail. He will give you a justice badge.
Step 4.
Find a zone, rezone yourself, then go back to kohlo-lokolo, watch the next cutscene, and trade him the 4 wild onions. This time he gives you a scroll of blaze spikes.
Step 5. Take the justice badge and blaze spikes scroll to the AH and send them to your main account. Then log in to your main collect the booty, and put em on the auction block. Ussually you will get 5k for a justice badge, and, on my server, 30k for a scroll of blaze spikes.
Step 6.
Delete your windurst account and remake it, then repeat the steps. What your basically doing is investing about 4.1k into 2 quests per turn, and getting 35k back from it. Details on the 2 quests are found here if you are having trouble getting them done:
