Cerberus Drop Simulator

How Cerberus loot works

Cerberus always drops infernal ashes, then rolls a single weighted main table (total weight 130 on the wiki). Four of those weight slots are uniques — primordial, pegasian, and eternal crystals plus smouldering stone — so each is effectively 1/520. The rest of the table is commons: rune armour, runes, coal, restores, pies, noted bones, seeds, and key master teleports.

Tertiary rolls are independent: ensouled hellhound head (1/15), elite clue (1/100), jar of souls (1/2,000), and the Hellpuppy pet (1/3,000). Brimstone keys only appear on Konar tasks and are omitted here.

Why players simulate Cerberus

Boot upgrades (primordial / pegasian / eternal) are long ironman and main-game grinds. Expected kills per specific crystal is 520, but dry streaks past 1,500+ are common. Running 2,000–5,000 kills in the simulator shows how clumpy crystal RNG feels compared with the average, and how often Hellpuppy appears relative to stones.

FAQ

What is the crystal drop rate at Cerberus?

There is a 1/130 chance to hit the unique table. That table equally splits primordial, pegasian, eternal crystals, and smouldering stone — about 1/520 each.

Do I need a Slayer task?

Yes. Cerberus can only be fought on a hellhound or Cerberus Slayer task (level 91 Slayer, boostable). The simulator models loot only, not task restrictions.

How rare is Hellpuppy?

Hellpuppy is a tertiary 1/3,000. Jar of souls is 1/2,000. Elite clues are 1/100. Ensouled hellhound heads are 1/15.
