OSRS Stun-Alching Guide: Is High-Cost Magic XP Worth the Click?

Game screenshots and facts are cited from the Old School RuneScape Wiki (strategy, equipment, drops, and related pages). Writing is original editorial, not a copy of the wiki article.

Stun-alching is one of the most misunderstood training methods in Old School RuneScape. The name suggests a single technique, but it’s actually a two-spell cycle that combines Stun, a level 80 combat spell, with High Level Alchemy, the iconic money-making utility unlocked at level 55. Cast both on the same game tick, and you collect Magic XP from both actions without moving from your square. That sounds like AFK heaven—but the reality is a high-APM, high-cost grind that only makes sense for a specific type of account.

This guide pulls together the mechanics, unlocks, and realistic cost picture from the official wiki so you can decide if stun-alching deserves a place in your training plan. We’ll also cover the honest shortcuts: when buying gold to fund soul runes or paying for a training service beats grinding out the cash yourself.

What Stun-Alching Actually Is

Stun-alching is a manual casting cycle on the standard spellbook. You cast Stun on a nearby target, then immediately cast High Level Alchemy on a noted item in your inventory. Because Stun is a combat spell and High Level Alchemy is a utility spell, their global cooldowns do not overlap—you can fire both in the same tick, collecting the Magic XP from each action. This makes the method one of the fastest standard-spellbook training options, though the true rates depend on your clicking accuracy and current rune prices.

A typical cycle starts with a target that can be stunned repeatedly without dying. Many players use a combat dummy in a player-owned house, while others safespot a low-level NPC that won’t retaliate. You need a stack of alchable items (usually noted) and enough runes for both spells. The cycle repeats every few game ticks, so you never move but you are constantly clicking.

• Stun requires 1 soul rune and 12 earth runes per cast (verify exact rune counts on the wiki).
• High Level Alchemy requires 1 nature rune and 5 fire runes per cast, though a staff can eliminate the elemental rune cost.
• Each cycle grants XP from both spells; the total per cycle is the sum of Stun XP and High Alch XP.

Requirements and Unlocks Before You Start

Before you reach level 80, the wiki’s pay-to-play Magic training guide recommends a variety of methods to blast through the early levels. Quests like Witch’s Potion and Imp Catcher can skip levels 1–10 with almost no effort. From there, Enchanting bolts is one of the fastest ways to train while running or doing other activities, but it is extremely expensive. Low Level Alchemy at level 21 and High Level Alchemy at level 55 offer cheaper, more passive alternatives. For perspective, the wiki lists enchanting dragonstone bolts as granting 429,000 XP/hr at a cost of 28.86 GP/XP, while enchanting opal bolts at level 4 grants 49,500 XP/hr at 29.67 GP/XP. Low Level Alchemy provides about 60,000 XP/hr standing still and is far cheaper, which is why many players use it from 21–55.

Once you have the levels, choosing the right gear matters. A mud battlestaff provides unlimited earth and water runes, which covers the earth requirement for Stun; a staff of fire eliminates the fire rune cost for High Alchemy. You can combine one elemental staff with purchased runes for the other spell, but the soul and nature rune costs remain unavoidable.

Why Stun-Alching Isn’t Really AFK

In OSRS, “AFK” often means low attention, not truly away from keyboard. Methods like splashing require only a click every 20 minutes to stay logged in, while high alching while running lets you click once per inventory item while moving. Stun-alching is neither. You are stationary, but you must cast two different spells every 2–3 ticks, which translates to several hundred clicks per minute. That is significantly more intense than standard alching, because you have to alternate between two spells and keep an eye on your target and alch stack.

The misconception likely comes from the fact that you don’t move, which feels AFK compared to running between monsters. But the mental load is high, and fatigue sets in quickly. This is not a method you can do while watching a movie unless you’re okay with drastically reduced XP rates from missed ticks.

The Cost of Stun-Alching: Soul Rune Math and Breakthroughs

The dominant cost factor in stun-alching is the soul rune. Every Stun cast consumes one soul rune, and unlike High Alchemy, there is no item conversion to offset the expense—you simply spend the rune for the XP. Nature runes add a smaller but still significant cost per cycle, especially when you multiply by thousands of casts per hour. Earth and fire runes can be supplied by an appropriate staff, but you can only use one staff at a time; most players choose a mud battlestaff or staff of fire and buy the remaining elemental runes.

To understand the math, break down your cost per cycle:

• Soul rune × 1 (fixed, unavoidable)
• Nature rune × 1 (fixed, unavoidable)
• Earth runes × 12 (can be zero with mud battlestaff or earth staff)
• Fire runes × 5 (can be zero with staff of fire)

Multiply that per-cycle cost by the number of cycles needed to reach your goal. For 80–99 Magic, you need 11,048,363 XP. If Stun grants 90 XP and High Alchemy 65 XP (155 combined), that’s roughly 71,280 cycles. At even a few hundred GP per cycle, the total cost climbs into the tens of millions—and soul runes alone often push the figure higher. The exact amount fluctuates with the Grand Exchange, so always verify current prices before you commit.

To put the GP/XP into context, the wiki’s bolt enchanting table shows GP/XP values ranging from roughly 8 to 59 depending on the bolt tier, while High Alchemy is often close to zero or even profitable with the right items. Stun-alching’s GP/XP will be higher than High Alchemy because the soul rune cost is dead weight. Compared to other high-level methods, stun-alching has a worse GP/XP ratio than High Alchemy alone. It also lacks the Slayer and combat XP of bursting/barraging on Ancient Magicks. The upside is pure Magic XP speed and the convenience of not moving.

When Should You Start Stun-Alching?

You cannot cast Stun until level 80 Magic, so that is the absolute minimum. But is level 80 the right time to switch? The answer depends on your goals. If you are training Slayer alongside Magic, bursting or barraging on Ancient Magicks from level 62 or 70 onward is often macro-efficient: you gain Slayer, Hitpoints, and Defence XP while the drops can offset rune costs. If you are purely after Magic XP and have a fat cash stack, stun-alching becomes viable the moment you unlock Stun.

Some players wait until they have a large surplus of soul runes from PvM drops or until they’ve finished other expensive buyables. Others use stun-alching for short bursts when they want a quick level, then switch back to passive high-alching while doing Agility or questing. There is no universally “best” level to start beyond 80; the real decision is whether the cost and click intensity fit your account plan.

For maximum efficiency in a macro sense, the wiki notes that defensive casting can train Defence alongside Magic, but Stun is a manual cast and cannot be set to defensive autocast. If you want Defence XP while training Magic, burst/barrage on Slayer tasks is the better route. Enchanting bolts can outpace stun-alching in raw XP per hour at some tiers, but the GP/XP is also severe, so stun-alching becomes a middle ground once you hit 80.

Stun-Alching vs Other High-Level Magic Training

To put stun-alching in perspective, compare it against the other high-level training options from the wiki. The table below uses relative terms; check the wiki for exact XP rates and current costs, as they shift with market prices.

Common Mistakes and How to Avoid Them

• Using a monster that retaliates or dies. Stunning a low-HP monster can kill it or force you to eat, breaking the cycle. Use a combat dummy in a POH or a safespotted NPC with high HP that won’t fight back.
• Ignoring the staff slot. Not using a mud battlestaff or staff of fire means buying thousands of extra elemental runes every hour, ballooning costs for no benefit.
• Expecting AFK. Going into stun-alching thinking you can watch a show will result in missed ticks and lower XP rates. Treat it as high-intensity training.
• Alching the wrong items. High Alchemy’s value depends on the item’s alch price versus its GE price. Choosing items with a large loss adds insult to injury. Use a profit/loss calculator from the wiki community to pick break-even or profitable alchables.
• Not budgeting for soul runes. Soul runes are the single biggest expense. Buying too few stalls your session; buying too many at a bad price wastes GP. Check market trends and set a stop-loss.
• Overlooking alternative XP sources. If you still need Slayer or Defence XP, burst/barrage tasks may give better overall account progress for the same rune investment.

Time, Cost, and the Honest Shortcut

From level 80 to 99, you need 11,048,363 Magic XP. If stun-alching delivers around 150,000 XP per hour in real-world clicking conditions (community averages; verify on the wiki), that’s about 73.6 hours of non-stop casting. At 200,000 XP per hour, it drops to 55.2 hours. Neither is a short grind, and the cost in soul runes alone will be substantial—easily tens of millions of GP depending on market prices.

This is where the honest shortcut enters the conversation. Buying OSRS gold to cover rune costs is a time-for-money trade many players make to skip low-profit money-making methods. Alternatively, a trusted training service can level Magic on your account while you focus on real life. Both options have risks: third-party services may violate Jagex’s terms, and you should always use a reputable provider and understand the consequences.

If you prefer to stay entirely within Jagex’s rules, stick to high alching while doing Agility or burst on Slayer tasks. Both methods reduce the opportunity cost of Magic training dramatically.

Practical Next Steps

Ready to try stun-alching? Set up your session with this checklist:

• Reach 80 Magic and have High Level Alchemy unlocked.
• Acquire a mud battlestaff or staff of fire, based on current rune prices.
• Buy soul runes and nature runes in bulk; get earth or fire runes as needed.
• Choose a safe target: a POH combat dummy is ideal; otherwise safespot a high-HP NPC.
• Fill your inventory with noted alchable items that have minimal loss per alch.
• Position yourself within casting range of the target and with a clear view of your inventory.
• Start the cycle: cast Stun, then immediately click High Alchemy on a noted item. Repeat.
• Track your XP per hour with RuneLite or a calculator and adjust if it’s too low.

If the cost becomes too much, pivot to cheaper alternatives. High Level Alchemy remains one of the most versatile Magic training methods because it can be combined with Agility, questing, or other movement-heavy activities.
