ya it was a big ta doo with turning in blue essence cuz it wasnt tracked per person. so a stealther could sit and watch people droppin blue essence on the npc and then after like 35 of em the stealther could try to drop a few and steal the robe. or someone would drop 30 and give up, not knowing it might take like 50 and so the next person would get one for like 20 essence.
nowadays with the easy ways to get big luck on other items, the luck garb isnt as big of a draw anymore, except for collectors.
