Dice Distancing #54 Athanasia how far do dice roll?

About Athanasia, from BoardGameGeek:

Athanasia is a Scifi/Fantasy Competitive Skirmish Wargame where players engage in tactical conflict to secure the key to immortality. Players mobilize and strategically position their characters, leverage their surroundings to increase their power, and battle their rivals as they venture towards victory. Every character has a value that determines their health, movement, defense, and attack power as well as additional character abilities that increase their effectiveness on the battlefield. Each turn, a player is allotted 3 activation points for their civilization which they can use in a variety of ways to increase their own power as well as decrease their rival's power as they carve their path towards victory. In a given turn a player may: Move their characters across the battlefield based on their allowed movement, collect and activate items that spawn dynamically, activate obelisks to increase their movement, defense, and attack power, activate character abilities to weaken their rivals, and attack or steal items from adjacent rivals using a D20 die to simulate battle. As in any battle, strength in numbers always helps you come out on top. When attacking or defending from rivals, you get additional D20 roll or defense bonuses by positionally linking your characters together. Securing the key to immortality first requires crafting it at the crafting table in the center of the battlefield using both the philosopher's stone and antimatter which are spawned throughout the game. The race is then on for a civilization to secure the key and activate it at the battlefield's exit point. The player that successfully activates the key at the exit point is the winner. Alternatively, you can win Athanasia by being the sole survivor after obliterating your rivals. Will you be the first to reach immortality? -description from the publisher
