ToA Loot Calculator Formula
Unique Chance (%) = (Total Team Points / 10,500) × (1 + (Raid Level – 300) / 100)
Note: Thresholds and scaling shift significantly at Entry, Normal, and Expert tiers.

Variables Explained
- Raid Level (RL): The difficulty determined by active invocations. Higher RL significantly increases unique rates.
- Team Size: Points scale with more players, but the “Unique” chance is shared across the team.
- Individual Points: Earned from damage and room completions. A standard solo 300 RL is roughly 20k points.
- Deaths: Each death reduces your points by 20% (accumulative), drastically lowering loot quality.

What is the ToA Loot Calculator?
The Tombs of Amascut Loot Calculator is a tool designed for Old School RuneScape players to predict the probability of receiving a “Purple” unique item at the end of a raid. By factoring in Invocations and individual performance, it removes the guesswork from your farming efficiency.
Understanding the point-to-percentage ratio allows players to decide if adding specific Invocations (like “Walk the Path” or “Insanity”) is worth the added risk relative to the increased drop rate.
How to Calculate ToA Loot (Example)
- Select your Raid Level (e.g., 400 Expert).
- Determine your Team Size (e.g., 3 players).
- Calculate base points: A 400 RL raid yields ~25,000 points per player if no deaths occur.
- Apply the unique multiplier: At Expert levels, the divisor for a unique drop is lower than Entry levels.
- The calculator combines these to show your 1 in X chance of an Osmumten’s Fang or Tumeken’s Shadow.
Frequently Asked Questions (FAQ)
Does Raid Level affect the chance of a Shadow? Yes, the higher the Raid Level, the higher the chance of any unique, including the Tumeken’s Shadow.
How much do deaths hurt my loot? A single death reduces your current points by 20%. This can turn a guaranteed profit run into a waste of time.
What is the “Soft Cap” for points? While there is no hard cap, points over 64,000 in a single raid have diminishing returns on unique rates.
Are solo raids better than teams? Solos offer 100% of the purple chance to you, while teams split the chance, though team raids are often faster.
