1) Do the ol mahum badge quest till you have a large number of badges.
2) Wait for bad item lag (this occurs most on Sieghardt)
3) Use soulshots to find out when the lag is there.
4) While lagging, open the quest NPC’s chat, then close it, and re-open it multiple times.
5) You will crash when the item lag is done.
6) You will reboot having (the amount you were supposed to have, multiplied by how many times you opened NPC).
