I've pondered through this thread and have come to the conclusion that what is needed is a way to give players incentive not to wear the item.
A way to achieve this is to after this week add some sort of negative attribute to the item that will to some extent weight up to the gain of luck. For the luck item in particular I've compiled a list of three different attributes that could make sense:
  • When wearing the item you are moving slower, this due to you have to drag that big bag of expensive items you've collected.
  • When wearing the item you will loose money over time, as it can bee seen in the animation that you drop coins all the time
  • When you wear the item you will make less damage as you are trusting your luck to too much and forgot to train


Also unless it's already possible, the item should be tradeable and giftable (not sure it's a word).
