How to unlock the Expensive Look achievement in Ring of Pain - Definitive Guide
As the description states, save up enough souls to spend 200 re-rolling in addition to the cost of the chest (if not using a free one), and then discard the items. This can be detrimental to your run so it is not recommended to attempt this on an otherwise successful run if looking to complete the run afterwords.
