High Level Alchemy converts an item into coins at roughly 60% of its high alch value, so profit comes down to one thing: finding items whose Grand Exchange buy price sits below their alch value. Because GE prices move constantly, this is about knowing which categories to check rather than memorizing a fixed list.
Rune equipment: the most consistent category
Rune platelegs, plateskirts, kiteshields, and 2h swords are the classic high-alch staples. Their alch values sit around 38,000–39,000 gp, and they frequently trade below that on the Grand Exchange, with generous buy limits (70–125 per 4 hours) that make them easy to restock in bulk.
Budget items under 30,000 gp
If you’re working with a smaller bankroll, battlestaves (around 7,500–8,500 gp), broad bolts, adamant platebodies (around 9,000–12,000 gp), rune med helms (around 10,500–11,000 gp), and strung yew longbows (often under 1,000 gp) are commonly profitable and don’t tie up much capital per item.
Higher-value items
Dragon longswords and dragon daggers can be profitable when their GE price dips below alch value — a dragon longsword alchs for 60,000 gp, so even a small margin per item adds up fast if you’re buying in bulk. These carry more capital risk since a single item costs much more than a rune platebody.
Overlooked categories
Jewelry and enchanted items (rings, necklaces, amulets) are easy to skip past but can spike in alch profitability when demand for them dips. Crafted items like battlestaves and dragonhide bodies also benefit from steady supply via skillers, which keeps their GE prices more predictable than combat gear.
How to actually find profitable items
Prices shift constantly, so a list that was profitable yesterday can be a loss today. Use a live alchemy profit calculator that pulls current Grand Exchange prices rather than relying on a static list — check margins right before you commit to buying in bulk.
Bottom line
Rune equipment is the most reliable category for consistent high alch profit due to stable demand and generous buy limits. Branch into budget items if capital is tight, or dragon-tier weapons if you have more gold to work with — but always verify current GE prices with a live calculator before buying in bulk, since margins move fast.
