Many of the power-ups/power-downs in POE show their duration via an icon in the upper-left of the UI. However, when Bone Offering or Flesh Offering are used, there is no way to know how long it will last. I wonder if this was an oversight in development.
Is this a deliberate choice by the developers? Has this been discussed in the community? (I did a search but nothing relevant came up. I may be using the wrong search criteria.)
