Talisman: Digital Edition

One of the Monk's abilities allows him to add 1 to the dice roll when praying. The easiest place to do so is the Chapel, on the lower left corner of the Outer region, but other locations are also available: the Temple, the Shrine and the Idol also count. Even the Graveyard could be an option if you change your alignment to Evil.

The achievement unlocks when you click on the button to add +1 to the die roll.
