Pick any boss, raid or activity, simulate the grind, and watch the loot pile up. Real drop rates, honest odds, and a collection log you can actually fill.
Enter your RuneScape name to pull your real collection log from RuneProfile — owned slots get ticked and the simulator only counts new unlocks. (Your log must be synced via the RuneProfile RuneLite plugin first.)
How dry or lucky you are on every tracked drop for the boss you're viewing in the log. Punch in your real kill count and we'll show the odds and where you sit against everyone else grinding it.
Simulate Old School RuneScape boss drops and collection-log progress across 52 activities — God Wars Dungeon, Nex, Zulrah, Vorkath, the Corrupted Gauntlet, Chambers of Xeric, Theatre of Blood, Tombs of Amascut, the Desert Treasure II bosses, Araxxor and every clue tier. Set a kill count and roll the exact OSRS Wiki drop tables instantly, value the loot with live Grand Exchange prices, and check how dry or lucky you are at your current KC. Enter your RuneScape name to import your real collection log (RuneProfile) and kill counts (OSRS hiscores).
Being “dry” means you have killed a boss far more times than its drop rate suggests without getting the drop. Each kill is an independent roll with no pity timer, so being dry just means you are in the unlucky tail of the probability curve.
Zulrah's main uniques each drop at 1/1,024, with any unique roughly 1 in 128 kills. Enter your Zulrah KC and the simulator shows the percentage of players who would already have the drop — above about 75% means you are statistically dry.
The Twisted bow is one of the rarest Chambers of Xeric uniques. Enter your raid count and the simulator computes your exact percentile, showing how your count compares to the median raids needed.
Drop rate is the chance per kill (for example 1/512). The average kills to a drop equals that denominator, but the median is lower: for 1/512 the median is about 355 kills, so half of players get it before the drop-rate number.
The Skeletal visage drops from Vorkath at 1/5,000. By 4,000 kills roughly 55% of players have it, so a dry streak past about 3,465 KC puts you in the unluckier half.
