The short version
30-second read- Zulrah needs Regicide up to Port Tyras. Vorkath needs Dragon Slayer II, and both run in an instance with a deathbank.
- The serpentine visage is roughly 1/512. It rolls twice at 1/1,024 per Zulrah kill, and the helm needs 52 Crafting to make and 75 Defence to wear.
- Soloing a group boss keeps the whole drop. Expect longer kills and a thinner margin for error than at bosses built for one player.
- Learn a solo Chambers of Xeric raid next. Six entries here are CoX bosses, and CoX has no quest or skill requirement to enter.
Best Solo Bosses in OSRS by Account Stage
The best solo bosses in OSRS depend on your account stage. Early accounts start with Scurrius, the Giant Mole and Barrows. Zulrah and Vorkath are the steady money bosses, and the Corrupted Gauntlet and the Desert Treasure II bosses come once your stats can take them. Zulrah needs Regicide done up to Port Tyras and Vorkath needs Dragon Slayer II. Both fights run in an instance with a deathbank, and Zulrah is solo-only, so every drop is yours.
The table picks one or two bosses per stage. The full list of 81 bosses you can kill alone follows it, sorted by difficulty, with the requirement and the drop that makes each one worth farming.
| Stage | Boss | Requirement | Why farm it |
|---|---|---|---|
| Free-to-play | Obor and Bryophyta | Giant key or mossy key | Hill giant club; Bryophyta's staff saves 1 in 15 nature runes |
| First members boss | Scurrius | None (Varrock Sewers, private instance available) | Built for 60–90 combat players to learn boss mechanics |
| Early members | Giant Mole | Spade + light source | Mole claw and skin on every kill, traded to Wyson for bird nests |
| Early members | Barrows brothers | Priest in Peril | Barrows armour and weapons from the chest |
| Mid-game money | Zulrah | Regicide (up to Port Tyras) | Tanzanite fang, magic fang and serpentine visage at about 1/512 each per kill |
| Mid-game money | Vorkath | Dragon Slayer II | Vorkath's head 1/50 (guaranteed on kill 50), dragonbone necklace 1/1,000 |
| Slayer | Kraken | 87 Slayer + cave kraken task | Trident of the seas and kraken tentacle |
| Late game | Corrupted Hunllef | Song of the Elves + one regular Gauntlet clear | No items brought in; armour and weapon seeds 1/50 each, enhanced weapon seed 1/400 |
| Late game | Vardorvis and the other DT2 bosses | Desert Treasure II | Vestiges for the ultor, venator, magus and bellator rings |
Zulrah is also the boss behind the serpentine helm. The fight follows set rotations, so learning them matters more than another gear upgrade. If you want the kill count without the learning deaths, there is a Zulrah service.
Overview: Bosses You Can Do Alone
81 of the bosses in our index can be done alone, and 49 of those are solo content by design rather than a group fight you happen to be able to solo.
The distinction matters when you are picking one. A boss built for solo play has a fight length and supply cost that assumes one player; a group boss you are soloing usually means longer kills and a thinner margin for error.

FAQ
What are the easiest bosses to solo in OSRS?
Obor, Bryophyta and Brutus. All three are free-to-play: Obor and Bryophyta sit behind a giant key and a mossy key, and Brutus opens after The Ides of Milk. On members worlds, Scurrius is aimed at 60–90 combat players and the Giant Mole only needs a spade and a light source.
Can you solo Zulrah for the serpentine helm?
Yes, and you have to: Zulrah is a solo-only instance. The serpentine visage drops at 2 × 1/1,024 per kill, roughly 1/512, and a chisel turns it into a serpentine helm at 52 Crafting. The helm needs 75 Defence and Zulrah's scales to charge, 11,000 for a full charge.
Which solo boss should I learn first?
The lowest-difficulty entries above. Everything at difficulty 1 and 2 is covered in best bosses for beginners.
Is soloing worse than teaming?
Slower per kill, but you keep the entire drop and you are not waiting on anyone. For unique hunting that trade is usually worth it.
Still stuck on a mechanic? Ask the team on our Discord, it is free.
Bottom Line
81 entries, difficulty 1 to 5.
Start at Brutus (the Cow Boss) or Scurrius, move to Zulrah and Vorkath once you have Regicide and Dragon Slayer II, and treat the Corrupted Gauntlet and the DT2 bosses as the late-game solo grind. The ceiling here is Yama.
If you want one thing to learn after this list, make it a solo Chambers of Xeric raid: 6 of the entries here are CoX bosses, and CoX has no quest or skill requirement to enter.
Each row links to its own guide for mechanics and drops.
