OSRS Zulrah Calculator

Zulrah's drop table

Every kill gives 100 to 299 Zulrah's scales, then rolls this table twice, so each chance below is for one roll and then for a kill. Each roll has a 1 in 256 chance of the unique table and otherwise lands on one of 249 slots: 10 of them roll the flax table, where 10 in 5,264 give each mutagen, 12 the shark table and 10 the rare drop table.

The rare drop table

Zulrah reaches the rare drop table 10 times in 249 rolls. A ring of wealth takes the empty slots out of its gem and mega-rare tables, which makes those items likelier, and without Legends' Quest the gem table gives a nature talisman where it would have reached the mega-rare table. With Legends' Quest and no ring of wealth:

The tertiary drops

These roll once a kill each, beside the drop table. A brimstone key drops only on a Konar task, and the Elite combat achievements make an elite clue 5% likelier.

The setups

The pace of the two usual ways to kill Zulrah: a toxic blowpipe and trident of the swamp, and a maxed setup with a twisted bow, Tumeken's shadow and a Sanguinesti staff. Type your own kill time to replace them. The boss gp per hour calculator sets Zulrah beside every other boss at the same prices.

Zulrah questions

How many tries before you have to pay? Until you have killed Zulrah 50 times, the priestess at the Zul-Andra dock gives your items back for free. From the 50th kill on, each death costs 100,000 coins. Ultimate ironmen never pay, and the elite Western Provinces Diary gives one free resurrection a day that lets you carry on the fight. On Hardcore Worlds, open since 4 November 2026, a death at Zulrah is not safe and costs your character its one life, unless that resurrection saves you. The achievement diaries calculator lists every task of the elite Western Provinces Diary.

Should you sell a fang or dismantle it? A tanzanite fang, magic fang and serpentine visage each dismantle into 20,000 Zulrah's scales. Pick "Whichever pays more" in the panel to value each one the better way at today's prices.

What changes in Deadman Mode? On the permanent Deadman world each combat bracket doubles the chance of the uniques on Deadman's list, which holds Zulrah's tanzanite fang, magic fang, serpentine visage and uncut onyx; a charged trinket of fortuity adds one more time the normal rate. Zulrah, at combat 725, can also drop charms (never while your PvP protection lasts), a tier 5 archaic emblem 1 time in 300, and a supply drop about 1 kill in 75, and an accumulation charm in your inventory triples the elite clue chance. Pick Deadman Mode under "Where you play" to count them.

Does a slayer task change the loot? Only on a Konar task, which adds a brimstone key 1 time in 50. The speed tasks must be done without a slayer task.

Where else to look? For Pet snakeling against every other pet, the pet calculator has them side by side, the dry calculator has every other boss, and the combat achievements calculator plans every task.
