Tombs of Amascut is the most tunable raid in OSRS. The invocation board lets you move between a relaxed entry clear and a 600-point death run without changing rooms. Most players, however, get stuck not at the mechanics but at the jump from a 150 normal to a 400+ expert. This guide is for those players and for anyone who wants to buy a 400+ clear and needs to know what they are actually paying for.
We will cover raid level scaling, how to build a 400 invocation list, the gear that holds up, common wipe points, and exactly what a boosting service should promise before you hand over your account.
Understanding Raid Level and the Invocation System
Raid level is the number under your party UI when you tick invocations. It does two things: scales enemies and scales loot. For every 5 raid levels, NPC hitpoints, defence, accuracy, and damage increase by 2% additively. Damage is capped at +150% (so a 600 raid has +150% damage, not +240%). A 100 raid level makes everything 40% stronger; a 500 makes hp/def/acc 200% stronger and damage 150% stronger. That is not a linear difficulty curve. The jump from 150 to 400 means enemies hit roughly twice as hard and take twice as long to kill, while your supplies and time stay the same.
Raid level is not just a number; it is your unique drop multiplier. Higher raid level increases points and unique chance per completion, but diminishing returns after 400-450 for most players. Solo 450 profits average around 5.5m/hr while solo 545 averages 7.68m/hr, but the extra 95 raid levels come with significantly more risk.
Entry Raid vs 400+: What Actually Changes
The table below shows the practical differences between an entry run, a normal run, and a 400 expert. The numbers are additive stat boosts using the official formula.
| Aspect | Entry ~50 | Normal ~150 | Expert ~400 |
|---|---|---|---|
| NPC stat modifier | +20% | +60% | +160% (damage capped at +150%) |
| Typical attempts invocation | Unlimited or Try Again (+5) | Persistence (+10) or Softcore (+15) | Hardcore Run (+25) for points, or Softcore for learning |
| Death cost | Safe unless team wipes with no attempts | Up to 500k IRS fee on wipe | One wipe can end run; IRS fees up to 500k; risk of item loss if repeated deaths |
| Unique chance | Very low; no Masori crafting kit | Moderate | High; 350+ deathless gives Masori crafting kit |
| Time pressure | Optional | Optional | Often uses Walk for It (40 min) or Jog for It (35 min) |
| Gear floor | Rune crossbow, trident, whip | Fang, Bowfa, trident of swamp | Fang, Bowfa/Tbow, Shadow, Masori/Ancestral, defence drain |
| Invocation freedom | Nearly anything works | Must start making choices | Tight list; many mandatory for points |
Death in ToA with a limited-attempt invocation can cost your items via Item Retrieval Service up to 500k, and Hardcore status is always lost on death inside the raid. If you die a second time before reclaiming, items are permanently lost.
Building Your Invocation List to 400
There are 44 invocations in ToA. You do not need to understand all of them to reach 400; you need a core of efficient, low-risk points and then a few boss-specific choices. The attempt category is your first decision. Hardcore Run gives +25 raid level but only one attempt; that is where most 400+ raiders start. Pair it with Walk for It (+10) or Jog for It (+15) if you are confident in your pace. Path leveling invocations like Walk the Path add points but also make later bosses stronger; add them only after you have mastered the base bosses. Boss invocations are the most efficient point sources, but each one changes a specific mechanic. For example, Overclocked for Zebak and Upset Stomach for Ba-Ba are commonly enabled at 400, while Quiet Prayers and On a Diet are held for higher level or specialist runs.
- Start with Hardcore Run (+25) or Softcore Run (+15) if still learning.
- Add Walk for It (+10) or Jog for It (+15) for time points.
- Enable Pathseeker and Pathfinder if comfortable, then Walk the Path last.
- Stack boss invocations: start with Akkha's Feeling Special, Kephri's Lively Larvae, Zebak's Overclocked, and Ba-Ba's Shaking Things Up.
- Skip supply restrictions (On a Diet, Dehydration) until you are pushing 500+.
Build your list in the in-game interface, then test at 300 before jumping to 400. The difference in chip damage and boss health is very noticeable. Your goal is a list you can clear 90% of the time, not a list that occasionally clears 400.
Gear Requirements and Upgrades That Matter
Your gear is the second hardest filter. At 400, defence rolls are high enough that Osmumten's fang's passive becomes near mandatory for melee. The fang has two effects: on a miss, it rerolls accuracy once; on a successful hit, it rolls damage between 15% and 85% of your true max hit instead of 0 to max, pulling damage closer to average. This makes it exceptionally consistent against high defence. Its special attack, Eviscerate, costs 25% spec, gives 50% accuracy on the next hit and uses the true max hit, effectively adding 17.65% max hit for that hit. In ToA, almost all bosses are weakest to stab, so a fang is the first major purchase for expert.
For ranged, Masori armour (80 Ranged, 30 Def) is the best ranged armour, with no melee accuracy penalty unlike Armadyl. Fortifying with Armadyl plates requires 90 Crafting and 80 Defence, adding prayer bonus and the highest magic defence in the game. At 400, you will take heavy magic chip damage, so fortified Masori is a massive QoL increase. A full standard set costs roughly 95m, fortified roughly 161m as of this writing; verify live GE prices before buying.
Beyond fang and Masori, you need a reliable ranged weapon (Bow of faerdhinen or twisted bow), magic (Tumeken's shadow is BIS but expensive; trident/sang works), and defence reduction. Bandos godsword or bone dagger can lower boss defence, which is crucial at 400 because the raid level multiplier applies to the defence roll, not just level. Keep a Lightbearer ring to use special attacks more often.
Recommended minimum for a smooth 400: 82 Attack for fang, 80 Ranged/Defence for Masori, 77+ Prayer for Rigour/Augury, and at least a 50m bank for supplies and gear. If you are buying a boost, most providers expect you to have at least fang and basic supplies.
The Four Paths and Warden Under Pressure
The four paths can be done in any order, but invocations change that. For learners, start Zebak > Kephri > Akkha > Ba-Ba to avoid late-run deaths from Ba-Ba's falling boulders or Akkha's memory phase. Once you have the rhythm, Ba-Ba > Kephri > Akkha > Zebak is more efficient because the salt from the Path of Het boosts ranged and magic for Akkha and Zebak, and you get run energy restoration for Akkha. Path leveling invocations like Walk the Path make the later bosses stronger, so you must plan your supplies.
Each path has a challenge room and a boss. The Path of Crondis asks you to grow the Palm of Resourcefulness by carrying water containers while avoiding statues. Zebak is a ranged/magic boss with acid pools. The Path of Scabaras has a puzzle challenge and then Kephri, a melee/range boss with egg spawns. The Path of Het has a mirror room and Akkha, who has an enrage memory phase. The Path of Apmeken has a monkey agility challenge and Ba-Ba, who uses falling boulders. The final Wardens fight has two phases; disrupting the energy flow determines which warden you face first. Manage your supplies and prayer carefully; a single mistake at 400 can end a Hardcore Run.
Pre-pot before entering first path: divine super combat, ranging potion, saturated heart, and anglerfish overheal. Salt should be used before Akkha if doing Akkha before Zebak to maximize run energy for the memory phase.
Common Mistakes That Sink Expert Runs
- Not draining defence: fang helps, but BGS/bone dagger makes kills faster and safer. The raid level multiplier applies to defence roll, so reducing base defence is huge.
- Enabling path leveling without a plan: Walk the Path makes later bosses much stronger; if you can't handle Upset Stomach Ba-Ba, don't enable it.
- Poor invocation order: starting Ba-Ba without salt is slower; starting Zebak with Walk the Path can lead to chip damage at enrage.
- Forgetting to pre-pot: you lose first minute of each path to potting instead of damaging.
- Using Hardcore Run without practice: one disconnect can cost your items and run. If you are learning, use Softcore Run until comfortable.
- Underestimating Akkha's memory phase and Ba-Ba's boulder phase: these are the most common wipe points at 400.
- Not using preserve prayer with salt: salt boost lasts 8 minutes, but with preserve you can extend it across two bosses.
Never start a Hardcore Run 400+ raid on an unstable connection. A disconnect during a boss counts as a death, and if your team wipes, your items are at risk.
Time, Death Costs, and Why Boosting Is a Legit Option
Money making at expert ToA is strong: the wiki's money making guide lists 3.2m/hr for general expert, 5.5m/hr for solo 450, and 7.68m/hr for solo 545. But those numbers assume consistent clears and high unique luck. Learning 400+ takes dozens of hours, and each death can cost up to 500k in reclaim fees plus supplies. For players with limited time, buying a boost or an account is a legitimate choice. A reputable provider will specify the exact raid level, invocation list, number of clears, and who handles supplies. You are not paying for gear; you are paying for time and consistency.
If you're comparing ToA expert to other high-end raids, our CoX vs Challenge Mode guide outlines similar decision points on kit unlocks and service scoping.
Verify the provider's raid level and invocation list before paying. A 300 expert is not a 400 expert. Ask for screenshots or VOD of past 400+ clears.
What to Ask a ToA Service Provider (Buyer Checklist)
- What exact raid level will you run? (Not just "expert" — get the number.)
- Which invocations do you enable? (Ask for the list, including attempts, time, and boss invocations.)
- Do you use Hardcore Run or Softcore Run? What happens on a wipe?
- Do I need to supply my own items and potions? (Some services expect you to have fang, Masori, etc.)
- How many clears are included, and what uniques do I keep? (Be clear about split vs keep.)
- What is your average clear time and death rate at this invocation level?
- Do you offer a VOD or live stream for verification? (Transparency reduces scam risk.)
- What is your policy if my account gets a temporary ban? (Do not claim Jagex partnership; ask how they handle risk.)
All service terms should be in writing before you hand over credentials. If the provider cannot answer these questions, keep shopping.
Final Thoughts and Your First Expert Clear
The gap between a 150 normal and a 400 expert is the largest in ToA. It is not just more health; it is a combination of stat scaling, tighter invocations, and the mental load of one-attempt runs. Train with Softcore, buy a fang, and build your invocation list gradually. If time is your constraint, a vetted boosting service can clear 400+ for you while you keep the uniques. Just ask the right questions and verify the raid level.

Frequently asked questions
What raid level is considered expert in ToA?
Expert mode starts at 300 raid level. A 400 is often the first serious expert target because it unlocks higher unique chance and the Masori crafting kit at 350 without dying. Many players consider 400-450 the sweet spot for profit vs difficulty.
How many attempts do I get in a 400 ToA raid?
It depends on the invocation. Try Again gives 10 attempts, Persistence 5, Softcore Run 3, and Hardcore Run 1. Most 400 lists use Softcore Run while learning and Hardcore Run once confident, because Hardcore Run adds +25 raid level.
Is Osmumten's fang mandatory for 400 ToA?
Not strictly mandatory, but strongly recommended. The fang's passive reroll accuracy and average damage roll make it the most consistent stab weapon against high defence bosses like Ba-Ba and Kephri. Without it, you will notice slower kills and more chip damage.
What is the minimum gear for a 400 ToA expert?
You need 82 Attack for fang, 80 Ranged/Defence for Masori (or Crystal with Bowfa), and a decent magic weapon. Defence draining is important so bring a Bandos godsword or bone dagger. A Lightbearer ring helps with special attacks.
How do death costs work in ToA with Hardcore Run?
With Hardcore Run, the team has only one attempt. If the team wipes, you are ejected and your items go to Item Retrieval Service with a reclaim fee up to 500k coins. Dying a second time before reclaiming permanently loses the items.
What is the Masori crafting kit and how do I get it?
The Masori crafting kit is obtained by completing a ToA raid at raid level 350 or higher without dying. It can be combined with an Ava's assembler to create the Masori assembler, a BIS ranged cape slot item.
Should I buy a ToA 400 boost or learn it myself?
If you have time and enjoy the challenge, learning 400 is rewarding. If your playtime is limited and you mainly want the uniques or account progress, buying a boost is a legitimate time-saving option. Just verify the provider's raid level and death policy first.
