About On Drop Rate

On Drop Rate helps you check roughly how long you'd need to grind for an item, and whether you're actually dry right now, or just feeling like it.

We're passionate OSRS players, grinding since the game's 2013 release across multiple accounts and every seasonal game mode along the way.

This vibe-coded project is built and maintained by us.

Greetings from Team On Drop Rate.

The time to obtain Seers ring at Dagannoth Prime, if you are exactly on drop rate, will be 8 hours and 32 minutes with beginner gear, 5 hours and 49 minutes with average gear and 5 hours and 7 minutes in max gear. That is about 128 kills on average.

Customize your estimated kills per hour above to see your own time to be on drop rate.

Additional information

During this grind you will also be making roughly 3,539,609 gp in total loot — about 608,370 gp per hour at 22 kills per hour. The biggest earner over that stretch is Dagannoth bones at about 1,662,080 gp.

Each kill has a 0.7813% chance at Seers ring. Half of all players get it within 89 kills, 294 kills covers 90%, and 588 kills covers 99% — so going past 128 kills without one is unlucky, but not unusual.

Loot values use live Grand Exchange prices and shift with the market.
