The Basics
Other Magics is an RPG themed around creativity, problem solving, and whimsy. One player (the GM) controls the game world and adjudicates play, while the other players explore that world as spellcasting wizards.
Spells are created as they are cast by channeling a stored Essence - fundamental and specific properties, like Fire, Anger, or Orangutan, which vary little between instances.
Wizards collect Essences via Attunement - finding and focusing on an Essence in the environment and ‘storing’ a copy within an Attunement Slot until Burned to boost a spell, lost in Mishap, or discarded.
