Backstab

Subterfuge · innate (always on)

Subterfuge numbers are estimates

These formulas come from the community wiki and predate the game's overhaul. We check each school against the live game on a GM account; until Subterfuge is checked, read the numbers as ballpark. A combat balance pass across 200+ skills is also still in progress, so every number is provisional. (ledger #59)
