"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 ore value by x100 making it better in some aspects than True Overlord Device due to The Grand Prism not being a fine point upgrader. However it must be noted that the Grand Prism is two units wider. What makes The Grand Prism stand out from other items is its design (refer to the infobox).
