Join humanity in repelling the demon invasion. This companion app to the Catalyst RPG system helps a game master manage their players across an epic story of survival. This piece of technology helps them quickly organize their world, letting them focus on telling a rich story.


NPC creation: Quickly create and store numerous characters for battles. Catalyst’s growth point logic is built-in, ensuring your adversaries follow the rules. An over/under tracker shows how powerful your creatures are relative to the players’ current level, letting you gauge the difficulty of an encounter.

Battle mode: Catalyst’s card based combat is managed through this app. The battle participants are organized in reaction order. Cards can be chosen for all the GM’s characters, tracking vigor and vitae as the battle progresses. All this speeds up Catalyst’s already-fast combat system.
