ToA Loot Simulator

How It Works

The simulator calculates your unique (purple) drop chance based on three key inputs: your raid level, your reward points, and any deaths during the raid. Internally, it applies the official formula: your reward points are divided by a denominator that shrinks as raid level increases, giving you a percentage chance at hitting the unique loot table each completion.

Once the unique table is hit, the tool rolls among seven possible unique items using weighted probabilities. At normal raid levels (150–300), Osmumten's fang and the Lightbearer carry the highest weight (7 each out of 24 total), while Tumeken's shadow is the rarest at 1 out of 24. At expert raid levels above 300, fang and lightbearer weights gradually decrease, making rarer items like the shadow, ward, and Masori pieces relatively more likely per purple.

For common loot, the simulator performs three rolls on the standard supply table, calculating quantities based on your points and a per-item divisor. The result closely mirrors what you would see opening the chest in-game.

How to Use

1. Set your Raid Level using the slider or by typing a value (0–600). The mode indicator shows whether you are in Entry, Normal, or Expert.
2. Adjust Team Size if running group raids. Solo is the default.
3. Enter Reward Points — a typical deathless solo earns roughly 8,000–20,000 depending on performance and raid level.
4. Set Deaths if applicable. Each death costs 20% of your remaining points.
5. Click a Simulate button — run 1 raid for a quick result, or bulk-simulate up to 10,000 raids to see statistical distributions.
6. Explore tabs — check the Statistics tab for item breakdowns, the Dry Streaks tab for probability milestones, or the Log tab for a full chronological history.

Tips and Best Practices

• Minimize deaths. A single death costs 20% of your points, noticeably lowering your purple chance. Two deaths drop your points to 64% of the original — a meaningful difference over hundreds of completions.
• The 300 threshold matters. Crossing into expert mode (300+) gives a significant boost to unique rates and shifts item weights toward rarer drops. If you can comfortably complete 300, the statistical payoff is real.
• Diminishing returns above 450. Due to the scaled raid level formula (which compresses gains above 310), pushing from 400 to 500 gives a smaller rate boost than going from 200 to 300. Use the simulator to compare exact rates before committing to harder invocations.
• Use bulk simulation (1,000+). Single raids are fun but statistically noisy. Running 1,000+ simulations gives you a clear picture of expected item distribution and GP value.
• Track your GP/hr. Combine the simulator's expected GP per raid with your average completion time to estimate real GP/hr at different raid levels.

Common Mistakes

• Confusing total points with reward points. You start each raid with 5,000 base points. Reward points are everything above that base. Only reward points factor into loot calculations.
• Assuming linear scaling above 300. The scaled raid level formula applies diminishing compression above 310, so doubling your raid level does not double your chance.
• Ignoring death penalties in bulk estimates. If you consistently die once per raid, your effective purple rate is roughly 80% of the advertised deathless rate — that gap compounds over hundreds of raids.
• Comparing solo and group rates directly. In groups, the total team points are pooled for the unique roll, and your individual share is proportional to your contribution. A 5-man team doesn't give everyone the full solo chance.
