If you've been grinding Slayer, questing, and training skills — but feel lost when it comes to bosses — you're not alone. Most players hit level 70 combat stats and ask the same question:
"Which boss should I fight next?"
The answer isn't "just go kill Zulrah." That's how you lose 5M GP in supplies and quit bossing forever.
There's a specific progression ladder in Old School RuneScape, and following it will save you hundreds of deaths (and millions in wasted supplies). This guide covers every step from your first Barrows run to endgame bosses like Nex — with exact stats, gear requirements, and profit expectations for each tier.
This is the 2026 updated version, accounting for Sailing skill release, new equipment tiers, and the current meta.
The Big Picture: Why a Ladder Matters
Here's what most beginners get wrong: they watch a Zulrah or Vorkath YouTube guide, buy 2M worth of gear, go in blind, and die 15 times before giving up.
Every boss teaches you specific mechanics that build on the previous one. Here's what each tier develops:
| Tier | Focus | Example Mechanics |
|---|---|---|
| 1 - Basics | Prayer switching | Barrows brother prayers |
| 2 - Movement | Dodging while DPSing | Sarachnis web avoidance |
| 3 - Multi-Switch | Gear + prayer per attack phase | Gorillas style switching |
| 4 - Full Mechanics | Rotations, phases, tick manipulation | Zulrah, Vorkath |
| 5 - Endgame | Raids, team coordination, high APM | TOA, TOB, Nex |
Skip a tier = you'll hit a wall. Follow the order = steady progression with minimal waste.
Prerequisites Before You Start
Don't even think about bossing without these minimums:
- [x] 70+ in all combat stats (Attack, Strength, Defence, Ranged, Magic)
- [x] 43 Prayer at minimum (70+ recommended for Piety/Rigour/Augury)
- [x] Barrows Gloves from Recipe for Disaster
- [x] Dragon Defender (or better)
- [x] Rune Crossbow + Broad Bolts
- [x] Iban's Staff or Trident of the Seas
- [x] Basic PvM quests completed: Dragon Slayer, Desert Treasure I, Monkey Madness I
Total estimated setup cost: 1-2M GP (very affordable).

TIER 1: Learning the Basics
Step 1 — Barrows (Difficulty: ★☆☆☆☆)
The perfect first boss. Period.
| Stat | Requirement |
|---|---|
| Quest | Priest in Peril |
| Magic | 50+ |
| Prayer | 43+ |
| GP/hr | 500K–1M (1.5M+ with Morytania Hard Diary) |
Why start here: All six brothers use protection prayers, so you learn the fundamental skill of prayer switching. You also learn inventory management (prayer potions, food, spades) and basic gear switches (slayer staff → Iban's blast).
Pro tip: Complete the Morytania Hard Diary before you grind Barrows seriously. It doubles your rune drops from the chest, turning a decent money-maker into one of the best low-level activities in the game.
What you'll take forward: Prayer flicking rhythm, kill speed optimization, reward chest variance tolerance.
Step 2 — Sarachnis (Difficulty: ★★☆☆☆)
| Stat | Requirement |
|---|---|
| Melee | 65+ |
| Prayer | 43+ |
| Weapon | Crush (Vesta's Cudgel or Leaf-Bladed Battleaxe) |
| GP/hr | 600K–1M |
This is where movement enters the equation.
Sarachnis spawns minions that web you in place. You must reposition constantly while maintaining your DPS output. She also uses a rapid melee attack that rewards prayer flicking — reducing your prayer drain by 50% if done well.
This is the first boss where standing still = death. And that lesson applies to literally every boss after this one.

Step 3 — Crazy Archaeologist (Difficulty: ★★☆☆☆)
Located in level 23 Wilderness. Drops include:
- Rune Crossbow (essential upgrade)
- Odium shard / Malediction shard (valuable tradeables)
What this teaches: The fundamental bossing rhythm of move → attack → dodge → attack. Crazy Arch has three special attacks you must avoid by moving at least 3 tiles away. Miss the tell? You eat 40+ damage.
It's low risk (Wilderness, but level 23 is barely dangerous) and high teaching value. Spend 30 kills here until you can avoid every special attack instinctively.
TIER 2: Prayer & Movement Combined
Step 4 — Demonic Gorillas (Difficulty: ★★★☆☆)
| Stat | Requirement |
|---|---|
| Quest | Monkey Madness II (completed) |
| Melee/Range | 75+ |
| Key Item | Arclight (strongly recommended) |
| GP/hr | 2–3M (Zenyte shard at ~1/300 drop rate) |
Welcome to the real test.
Gorillas are where casual bossing ends and mechanical skill begins. Here's what makes them brutal for first-timers:
- Three attack styles (Melee, Range, Magic) — you must pray against the correct one
- Style changes every ~50 damage dealt — you need to track your damage output and switch prayers accordingly
- Acid pools spawn under you — constant movement required
- Stat drain — they lower your Defence, making positioning critical
- Three gorillas in an instance — you often fight 2-3 simultaneously
The skill this teaches is irreplaceable: simultaneous prayer tracking, damage counting, gear switching, AND positional awareness. If you master Gorillas, Zulrah will feel easy by comparison.
Expected learning curve: 20-50 kills before your first clean no-food kill. That's normal.
Step 5 — Grotesque Guardians (Difficulty: ★★★☆☆)
| Stat | Requirement |
|---|---|
| Quest | Song of the Elves |
| Slayer | No requirement |
| GP/hr | 1.5–2.5M (Jar components are valuable) |
Dusk and Dawn teach you phase-based mechanics. Each guardian has unique abilities:
- Dusk (first 50% HP): Slow but hits hard. Teaches patience and defensive positioning.
- Dawn (second 50%, awakened): Fast, aggressive, with multiple special attacks. Teaches reaction time and pattern memorization.
The transition between phases is something you'll see again at Vorkath, Zulrah, and every raid boss. Learn it here where the stakes are lower.

TIER 3: Full Mechanics Bosses
Step 6 — Zulrah (Difficulty: ★★★★☆)
The gatekeeper boss. If you can consistently kill Zulrah, you're officially not a beginner anymore.
| Stat | Recommendation |
|---|---|
| Range | 75+ (80+ ideal) |
| Magic | 80+ for Iban Blast |
| GP/hr | 2–3M (highly variable based on loot) |
Why Zulrah is different: Four distinct phases with different protection prayers, different attack styles, and different positions. You need to memorize:
- The rotation pattern (which phase comes next)
- Positioning for each phase (where to stand to avoid snakeling spawns)
- Prayer switching timing (when to switch Protect Magic → Protect Missiles)
- Inventory management (when to drink antidote+, restore, food)
Real talk: Your first 20 kills will be messy. You'll forget to switch prayers, stand in wrong spots, and panic during Phase 3. That's part of learning. By kill 50-100, you should be averaging 2+ kills per trip.

Step 7 — Vorkath (Difficulty: ★★★★☆)
| Stat | Minimum |
|---|---|
| Defence | 70+ |
| Range/Mage | 70+ each |
| GP/hr | 3–5M (consistent) |
Vorkath is the best money-making boss for mid-level players. Full stop.
Unlike Zulrah's variance, Vorkath pays out reliably. Each kill guarantees 80-120K in drops plus chances at:
- Vorkath's head (for Dragonbone Upgrades, ~15M)
- Skeleton Visage (rare, ~8M)
- Warped Sceptre (~3M)
- Dragonbone necklace (consistent 2-3M)
Key mechanics to master:
- Acid pool spawning — move every 15 seconds or eat massive damage
- Zombie respawn — one-hit KO if you don't fast-click it within 3 seconds
- Special attacks — two types, both dodgable with proper timing
- Phase switch — at 50% HP, Vorkath becomes more aggressive

TIER 4: Endgame Solo & Group Content
Step 8 — Theatre of Blood (TOB) — Entry Level (Difficulty: ★★★★★)
| Requirement | Detail |
|---|---|
| Quest | Sins of the Father |
| Combat | 80+ recommended |
| GP/hr | 5–10M (team of 4-5, highly variable) |
TOB is your introduction to raid-style bossing. Multiple rooms, multiple bosses, shared resources, and coordinated mechanics.
Start with entry-level teams (not elitist "5 man sub-20" groups). Look for practice teams in the "Party Guide" Discord or CCs specifically advertising "TOB learner raids."
Step 9 — Tombs of Amascut (TOA) — Solo (Difficulty: ★★★★★)
| Requirement | Detail |
|---|---|
| Quest | Queen of Thieves |
| Stats | 80+ across the board |
| Invocations | 150-250 for solos |
| GP/hr | 8–15M (at 300+ invocations) |
TOA is the pinnacle of solo PvM in 2026.
The Invocation system lets you customize difficulty. Start at 150 invocations (easy mode, good loot) and gradually climb to 300+ as you master each room's mechanics.
Room-by-room breakdown:
- Monkey God Baboon — Movement + prayer management (like Gorillas evolved)
- Kephri — DPS race with survival mechanics
- Zuk (not actual Zuk, but similar vibe) — Multi-phase boss with prayer switching
- Amascut — Final boss, combines everything you've learned

Step 10 — Nex (Difficulty: ★★★★★)
The current endgame king. Released in late 2025, Nex represents Jagex's most complex solo/group hybrid boss design.
| Requirement | Detail |
|---|---|
| Quest | Desert Treasure II |
| Recommended Stats | 90+ combat, 85+ slayer |
| GP/hr | 15–25M (extremely gear-dependent) |
Nex has five phases, each requiring different gear setups, prayer configurations, and mechanical execution. Teams typically bring 3-5 players with assigned roles.
Not there yet? No worries. Nex is designed for maxed accounts. But knowing it exists gives you a long-term goal — and the steps above will get you there.
Quick Reference: Which Boss Fits YOU Right Now?
Less than 200 total levels? → Start with Barrows. Build your bank, learn prayer switching.
Can do Gorillas but Zulrah feels hard? → You're in the right spot. Spend more time at Grotesque Guardians to polish phase awareness, then retry Zulrah.
Consistent Zulrah/Vorkath killer? → Time to learn TOA or join TOB teams. The jump from Tier 3 to Tier 4 is the biggest in the game, but also the most rewarding.
Want consistent money with low effort? → Vorkath is your answer. 3-5M/hour with very little mechanical complexity once learned.
Common Mistakes That Kill Your Progression
Skipping straight to Zulrah — Without Gorilla/Sarachnis experience, you'll develop bad habits (panic praying, poor positioning). Fix them early.
Underestimating gear upgrades — A Dragon Hunter Crossbow (Lance) doesn't cost much but DOUBLES your DPS at dragons/Grotesque Guardians. Invest in key upgrades before pushing harder bosses.
Ignoring the PvM Hub — The PvP Arena hub near Lumbridge has free item retrieval, instant banking, and boss portals. Use it instead of walking everywhere.
No kill count goals — Set targets like "I'm doing 50 Sarachnis kills regardless of profit" rather than stopping after one bad drop. Consistency > luck.
Learning from outdated guides — Pre-2025 balance changes affected many boss mechanics (especially TOA invocations and Vorkath's HP). Always use 2026-updated guides.
