High Alchemy — Margin Hunting, Not A Fixed Method
High Level Alchemy turns an item into a fixed coin amount. You profit when GE buy price + nature rune cost stays under that alch value. There is no permanent “best alchable” list — undercutting and nature price swings erase margins overnight. This is Magic training that sometimes pays; treat it as arbitrage, not a boss.
Skip if: you want a set-and-forget GP/hr number, or you will not check live GE prices before buying thousands of items.
High Level Alchemy
~1,000–1,200 casts/hr focused
Alch − buy − nature; often thin
5-tick cast loop
Hard gates
- 55 Magic for High Level Alchemy
- Nature runes — one per cast (main variable cost)
- Fire runes or a staff that provides fire (staff of fire / mystic fire / tome of fire)
- Cash to buy a test stack of alchables from the GE
Recommended
- Staff of fire (or better) — never buy fire runes for alching
- Rune pouch if you somehow need extra runes; usually natures + fire staff is enough
- Explorer's ring free Low Alchs are unrelated to high-alch profit — ignore for this method
- Alch calculator + GE Tracker open while buying
- Open the alch calculator. Sort by profit after nature cost. Ignore wiki nostalgia lists.
- Check real instant-buy price on the GE (not mid). Compare to high-alch value − nature cost.
- Buy 50–200 of the item. Confirm they fill. Alch the test stack. Confirm coins match expected margin.
- If margin holds, scale up. Cast High Alch on a 5-tick cycle: spell → item → repeat. Bank coins when inventory is cluttered.
- When buy offers stop filling or profit goes negative, drop the item. Rotate to the next positive line.
Typical categories that rotate in and out: yew longbows, various rune equipment, battlestaves, and other high-alch mid-items. Competition is fierce on anything the calculator highlights for long.
- Buy: alchable items + nature runes
- Do not buy: fire runes if you have a fire staff
- Output:coins equal to the item's high-alch value — no GE sell tax on alch coins
- Compare to flipping: sometimes selling on the GE after GE tax beats alching; sometimes alching wins because you skip the sell wait
Nature rune spikes can wipe an entire category of alchables in one day. Recalculate when natures move.
Per cast: high alch value − GE buy − nature cost. Throughput is capped by cast speed (~1,000–1,200/hr when focused). There is no unique RNG — variance is whether you can actually buy the item at the assumed price.
- 5–20 GP/cast only works if volume fills instantly
- Negative margin = pure Magic XP training; still valid if that is your goal
- Paper profit on mid-price means nothing if offers sit for hours
- Alching converts capital to coins without a sell listing — useful when GE is clogged
- Always fire staff — inventory slot and cost both matter
- Test 100 items before buying 10k
- Bank near GE so you can pivot items without a teleport tax on time
- F2P has fewer alchables; members markets are where thin margins usually live
- If two items show similar profit, pick the one with deeper buy volume
- Do not alch and flip the same stack — pick one exit
- Using guide price instead of what you actually pay
- Forgetting nature cost in the margin math
- Buying fire runes with a fire staff in the bank
- Holding a dead alchable because "it was good last week"
- Assuming 1,200 casts/hr while watching YouTube at half attention
