Conditions
All D&D 5e conditions in Onyx with their exact effects: blinded, charmed, frightened, grappled, prone, restrained, stunned, exhaustion and the rest.
Overview
Onyx gives the exact rules text for every condition in the Player’s Handbook and what each one does to attacks, movement and checks.
When to use it
Open a condition the moment a spell or monster applies it, so the whole table plays it the same way.
