"Most miners will live out their entire lives having never gazed upon the beauty and grace of the mythic Grand Prism."
The Grand Prism is a Slipstream-tier upgrader and the rarest of all Slipstream items. The upgrader was released on May 27th 2017 after having one month of anticipation after its photo was seen in Berezaa's inventory. The Grand Prism multiplies orevalue by 100x making it more powerful than True Overlord Device since The Grand Prism is not a fine point upgrader and the True Overlord Device but the Prism is two units wider. What makes The Grand Prism stand out from other items is its design (refer to the infobox).
