If you have ever stared down the barrel of 99 Agility and wondered whether you could make the grind do double duty, the answer is yes. Alch-gility is the classic efficiency method where you cast High Level Alchemy while running rooftop courses, turning mindless laps into simultaneous Magic XP. The catch? Doing it badly can tank your Agility XP per hour, burn through nature runes, and leave you clicking like a maniac for no real gain. This guide breaks down the method from inventory setup to run energy management, and shows you when buying gold or a boosting service is the honest shortcut.

Agility training is infamously click-intensive, but it also creates long stretches of running time where your character is essentially idle. That idle time is where alching fits perfectly. The goal is to cast High Level Alchemy during those travel ticks without delaying your next obstacle click. When done correctly, your Agility XP per hour barely moves, and you bank tens of thousands of Magic XP you would otherwise have to train separately.

Who This Guide Is For & Requirements

Alch-gility is aimed at a very specific type of player: someone who already has at least 55 Magic for High Level Alchemy and wants to train Agility efficiently while banking extra Magic XP. It is particularly popular with ironmen who have thousands of low-value alchables clogging their bank, and with mains who want to profit slightly or break even while they run laps. You do not need max gear or hundreds of millions, but you do need a stable supply of nature runes and a solid rooftop course unlock.

If you meet those basics, you can start combining from the moment you hit 55 Magic and any rooftop course. For players who have not yet reached 55 Magic, the fastest route is usually training Magic through quests, splashing, or low-level alching. Once you unlock High Level Alchemy, the real game begins.

If you are starting Agility from scratch, check out our OSRS Agility 1–40 Guide to decide between questing and low-level courses before you settle into rooftop laps.

Understanding the Alch-Gility Method

The core idea is simple: Agility courses force you to run between obstacles. Those running segments have a fixed travel time, and your character is not doing anything that requires a mouse click. High Level Alchemy has a cast animation of roughly three game ticks, during which your character can continue moving. If you click the next obstacle, then immediately click your alchable item, the spell will finish while your character is already in transit. The result is that you lose almost no Agility XP per hour and gain 65 Magic XP per alch (verify the exact XP in-game or on the Magic page, as it may change with updates).

This is different from stun-alching, where you stand still and alternate between Stun and High Alchemy to power-level Magic. Alch-gility is about layering Magic XP on top of an Agility grind you are already doing — not replacing a dedicated Magic training session. For players who want maximum Magic XP and do not mind standing in one spot, stun-alching is better. For those who want to chip away at Magic while getting Agility done, alch-gility is the king.

The method also works on non-rooftop agility courses, but rooftops are preferred because they have no entry fee, provide marks of grace, and usually have longer travel segments than obstacle-dense arenas. The Brimhaven Agility Arena and Wilderness Agility Course can also be alched on, but their higher intensity and risk make them less forgiving.

Inventory & Gear Setup for Alch-Gility

Your inventory and equipment loadout makes or breaks the method. A fire staff equipped in the weapon slot removes the need for fire runes entirely, saving one inventory slot per cast and preventing a common mistake: forgetting fire runes and having your alching interrupted every few minutes. If you do not have a fire staff, you must bring 5 fire runes per cast, which eats inventory fast and weighs almost nothing but is a needless hassle.

• Weapon slot: Fire staff, staff of fire, or charged tome of fire (the tome also frees the weapon slot if you prefer a different offhand).
• Nature runes: Bring at least 500–1,000 per hour, depending on how aggressively you alch. They stack, so one inventory slot is enough.
• Alchables: Non-stackable items you intend to alch. Bring as many as your inventory can hold after accounting for supplies. High-value rune items, dragonhide bodies, or noted items that you have unnoted in the bank are common choices. You cannot alch notes, so every alchable takes one inventory slot until you cast it.
• Stamina potions: 1–3 four-dose stamina potions per hour. They restore run energy and reduce drain rate, which is critical because agility laps constantly consume run energy.
• Food or boost pies: If your Agility level is close to the course requirement and you fail obstacles, bring a few summer pies or agility potions to boost your level and heal. Low Hitpoints players should always carry food.
• Weight-reducing gear: Boots of lightness, spottier cape, and any graceful pieces you own. The goal is 0 kg or below, which keeps run energy drain low without needing constant stamina sips.

A typical inventory for a mid-level player might look like: nature runes (1 slot), 4-dose stamina potion (1 slot), 8–12 alchables (depending on inventory space), and 1–2 summer pies. The rest are empty for course-specific items or more alchables. Once you alch an item, that slot frees up, so you can use the same inventory space multiple times across a lap if you bring alchables that convert fast enough.

Run Energy Management While Alching

Run energy is the silent XP killer in Agility. If your energy hits zero, your character walks, laps slow down dramatically, and your Agility XP per hour craters. Alching does not drain run energy, but it also does not recover it, so the entire burden falls on your gear, potions, and route planning. The Agility training guide is blunt: “For the fastest rates, players should always run and use stamina potions… Keeping weight at 0 or below is helpful, but not necessary.” Alch-gility players should take that advice and double down.

• Always use stamina potions before your run energy drops below 50% — a typical dose lasts about two minutes, so you need three doses per hour for continuous running.
• Wear weight-reducing gear. Boots of lightness and spottier cape are easy to obtain and bring most accounts to 0 kg or below. Graceful pieces also regenerate run energy faster when worn as a set.
• Avoid carrying heavy alchables. Rune platebodies are light per item, but dragonhide bodies and battlestaves can add up. Check your total weight before starting.
• Use the rest option or the musician NPCs at the start of some courses only as a last resort — standing still to rest loses more XP than just buying stamina potions.

If you find yourself constantly out of run energy, the problem is almost always one of three things: too much weight, not enough stamina potions, or alching so much that you forget to click the next obstacle and your character stops running. Fix the first two with supplies; fix the third by re-reading the timing tip.

Choosing the Right Rooftop Course for Alching

Not all rooftop courses are created equal for alch-gility. The best courses have long travel distances between obstacles, few click-intensive traps, and a predictable lap time that lets you plan exactly when to alch. Shorter, obstacle-heavy courses like Draynor or Al Kharid give you almost no idle time, so alching there will directly reduce your agility XP per hour. Longer courses like Seers’ Village, Pollnivneach, or Rellekka are community favorites because the run between obstacles is long enough for two or three alchs. You should verify the current unlock levels and lap layouts on the Agility training page before committing to a course.

If you are still low level, the same principle applies: pick the lowest-level course that already has some travel time. As soon as you unlock a longer course, move there. Combining alching with the wrong course is a classic trap — you end up losing 5–10% of your agility XP per hour just to gain a tiny amount of Magic XP, and that is a bad trade.

The table makes the tradeoff obvious: Hallowed Sepulchre is the fastest agility XP in the game, but it demands full attention, so alching is nearly impossible. Rooftop courses give up some raw agility XP but let you layer Magic XP on top. For many players, the combined total XP per hour (Agility + Magic) exceeds what they would get training both skills separately.

Alchable Selection & Managing Nature Rune Costs

Every High Level Alchemy cast consumes one nature rune, and nature runes are not free. The spell converts an item into gold at a fixed value, but the value is always less than the item’s Grand Exchange price for most alchables. That means almost every alch is a small money loser. The trick is to minimize that loss while maximizing inventory turnover. Items with a high alch value relative to their GE price are ideal — things like rune arrows, adamant platebodies, or battlestaves often have a loss of only 50–200 gold per alch. Dragonhide bodies tend to lose more per cast but can be bought in bulk and alched quickly.

Ironmen should alch anything they would otherwise drop or leave in the bank. Mains should compare the loss per alch to the XP gained. For example, if a nature rune costs 200 gp and an alchable loses 300 gp per cast, you are paying 500 gp for 65 Magic XP. That is often cheaper than bursting or splashing, but you must check current prices — the wiki does not set them, and they move constantly.

Some players bring stackable alchables to avoid inventory clutter, but most stackable items have poor alch values. A better approach is to bring 10–15 high-value alchables, alch them all during the first few laps, and then either restock from a bank between laps or bring a rune pouch full of nature runes and rely on alchable drops from course monsters (where available). Rooftop courses do not drop many alchables, so this mostly applies to Wilderness or other courses.

Common Mistakes & How to Avoid Them

Alching too often and missing obstacle clicks

The single most common alch-gility error. You click an alchable, the animation runs, and by the time it finishes, your character has already reached the next obstacle but you have not clicked it yet. Fix this by only alching after you have clicked the next obstacle, never before.

Running out of run energy

Agility laps drain run energy fast. If you do not bring stamina potions or you wear heavy gear, your character walks half the lap and your XP/hr drops by 30% or more. Always carry at least one 4-dose stamina potion per hour and keep weight at 0 kg or below.

Forgetting fire runes or using the wrong staff

High Level Alchemy requires 5 fire runes in addition to a nature rune. A fire staff removes that requirement. If you swap to a different weapon for the agility course, you will need fire runes again. Equip the fire staff and leave it on.

Alching items with a terrible GE-to-alch ratio

A 20,000 gp item that alchs for 8,000 gp is a horrible choice. Check the alch value before you buy a bulk supply. The wiki has a page for High Level Alchemy values, but you should verify current prices yourself.

Boosting Agility incorrectly

Summer pies and agility potions let you use higher-level courses before you have the natural level. If you boost too early and fail obstacles constantly, you waste food and time. Boost only to the minimum required, and bring enough pies or potions to last the entire session.

Time & Cost Tradeoffs: Is Alch-Gility Actually Worth It?

Let’s be honest: alching while running rooftops adds a small amount of time per lap. If you alch perfectly, the added time is almost zero because you are using idle running ticks. In practice, most players lose 2–5% of their agility XP per hour from misclicks and delayed obstacle interactions. Over the course of 100 hours of agility, that could mean 2–5 hours of extra grinding. In exchange, you might earn 500,000–1,000,000 Magic XP depending on how aggressively you alch. That Magic XP would otherwise take 5–15 hours of dedicated training. The net time saving is real for anyone who wants both skills.

The cost side is runes and alchable losses. Nature runes are a few hundred gold each, and alchables lose maybe 100–300 gold each. If you alch 500 times per hour, you are spending roughly 100,000–200,000 gp per hour on the magic component. That is trivial for mains with a steady money maker, but it can hurt ironmen or new players. If you are an ironman, the gold only matters if you need to buy nature runes from a shop — otherwise, the runes are free and the alchables are bank junk anyway.

For players who want the method without the moneymaking side hassle, buying OSRS gold can fund nature runes, stamina potions, and high-alch items upfront. That lets you train for hours without interrupting the grind to make money. If you would rather skip the agility grind entirely, a boosting service is the time-efficient alternative — but always use a reputable provider and understand the account safety risks.
