D20 Engine

Master the Action Economy

The D20 engine is a focused encounter and dice assistant in active refinement. It brings initiative, conditions, rosters, macros, and shared combat visibility into one table-side surface.

It supports rolls and tracking without replacing table adjudication: attack resolution, armor, class features, feats, and system-specific consequences remain with the GM and players.

Available alpha tools

  • Combat turn flow and initiative tracking.
  • Armor Class, hold, and incapacitated status tracking.
  • Check, attack, and damage dice pools.
  • Rosters and activity feed support for live play.

Alpha focused tools

  • GM Bestiary support for reusable NPCs and encounter prep.
