The D20 is an accessory in the Bunkers & Badasses game in Tiny Tina's Assault on Dragon Keep DLC
Used by a Bunker Master and by the players for various rolls and checks such as Initiative Rolls and Insight Checks
Description
20 sided die with a Vault Symbol for a Critical Hit (Or critical fail?)EDIT: The Vault symbol is confirmed in my experience to be a replacement for the number 20.
Caution
Roll dice carefully. Don't slam on the board as to not break any of the figurines.
