Sinister Chest Profit Includes Poison Management

Opening sinister chests converts keys into a fixed bundle of grimy herbs, but the method also poisons the player. A slash weapon, antipoison protection, inventory space, and level 49 Agility belong in the plan before the current herb margin matters.

The quote checked on 6 September 2026 estimated 383,115 GP per hour, with a range of 325,647 to 402,270 GP. The modeled capital requirement was 2,079,981 GP for 500 chest openings per hour. Key prices can move independently of the six herb outputs, so a large purchase magnifies spread risk.

One small trip gives better information than a full key stack. Count the keys opened before banking, record antipoison use, and sell the complete herb bundle. If poison forces an early exit or one herb sells slowly, the realized cycle differs from the model.

The warning details in this early-game OSRS method selector make the safety cost visible alongside the estimate. Profit per hour should never hide a mechanic that can cause death and interrupt the session.
