Quick answer: Cube a magic Heavy / Sharkskin / Vampirebone Gloves + Nef rune + Perfect Ruby + any jewel. Blood gloves always roll 5-10% Crushing Blow, 1-3% life leech and +10-20 life, plus up to 4 random rare affixes. The dream roll is +2 Javelin & Spear skills with 20% IAS ("2/20") — for that you need high-ilvl bases and your highest-level character doing the crafting.

The Blood gloves recipe

Blood gloves are one of the 36 Horadric Cube crafting recipes. Like every craft, the recipe is a magic (blue) base + a rune + a perfect gem + any jewel:

Every pair comes out with three fixed (preset) mods:

On top of that, the craft rolls 1-4 random rare affixes — the higher the output item level, the more affixes: ilvl 51-70 gives 3-4 affixes, and ilvl 71+ always gives the full four. Crafted items follow rare-item rules throughout, and Larzuk will only ever give them one socket.

Best base: Sharkskin vs Vampirebone vs Heavy

All three bases produce the same fixed mods, but they are not equal:

Where to get blue bases: gamble gloves on a high-level character, or farm high-ilvl zones (Hell Chaos Sanctuary, Worldstone Keep and other high-level areas from our farming spots guide) and keep every blue Sharkskin/Vampirebone pair you see.

Crafting levels: the ilvl breakpoints that matter

The output item level of a craft is ilvl = (character level / 2) + (base ilvl / 2), and the output's affix level decides which affixes can roll. The two chase affixes sit at affix level 40 and 43:

Practical rules: always craft gloves on your highest-level character, never a low-level mule — a low clvl can push the output below the affix thresholds no matter how good the base is. And prefer ilvl 76+ bases so both breakpoints stay reachable. For the full formula and the same breakpoints for rings, amulets and belts, see our crafting guide.

What to roll for (the 2/20 chase)

A perfect Blood gloves roll for a Javazon combines the fixed CB with four strong affixes. In priority order:

A clean 2/20 with useful leech and resists is one of the most valuable crafted items in the game — check current prices on the platforms in our trading sites guide before you settle.

Blood gloves not working? Every cause, checked

If the transmute button does nothing, it's one of these:

  1. Wrong base color. The gloves must be magic (blue). Rare, set, unique and white/gray/socketed gloves will not craft.
  2. Wrong base type. Only Heavy Gloves, Sharkskin Gloves and Vampirebone Gloves work. Light Gauntlets, Gauntlets and every other glove type belong to different recipes.
  3. Wrong gem quality. It must be a Perfect Ruby — Flawless and lower do nothing. Cube three flawless gems up first if you have to.
  4. Wrong rune. Nef (#4) for Blood gloves. Ort is Hit Power gloves, Ith is Safety — easy to mix up when batch-crafting.
  5. Missing jewel. Any jewel works, but one must be in the cube.

If the recipe worked but the result looks bad, that's not a bug — the fixed mods always roll, and the random affixes are exactly that: random. Batch-crafting a dozen bases is the normal way to fish for 2/20.

Blood gloves vs Hit Power gloves

The two glove crafts share the same chase affixes but different fixed mods, and they serve different builds:

Rule of thumb: spears and bosses → Blood; bows and knockback → Hit Power. Many Amazons craft both and swap per farm route.
