The Abyssal Whip is a two-step craft. You first make the Abysmal Whip, a power level 4 Vestige, from the Abyssal Demon‘s drops. Then you upgrade it to the Abyssal Whip, a power level 7 Masterwork, with materials from Dowdun Reach and the Umbral Sands.
Both steps happen at the Blacksmith's Bench and give 100 Artisan XP each.
Abysmal Whip vs Abyssal Whip
| Abysmal Whip | Abyssal Whip |
|---|
| Type | Vestige | Masterwork |
| Power level | 4 | 7 |
| Damage multiplier | 4.1x Slash | 4.1x Slash |
| Extra damage modifier | -0.5 | none |
| Crit chance | 15% | 15% |
| Durability | 1,300 | 1,600 |
| Weight | 4.5 | 4.5 |
| Effects | Bleed build-up | Abyssal Snare, Barbed, Reckless |
The Masterwork applies its multiplier at power level 7 and drops the Abysmal’s -0.5 modifier, so it hits much harder. Abyssal Snare is its special attack, which the Abysmal Whip doesn’t have. Reckless means the whip can only block using unarmed block. Both are one-handed.
Jagex reworked the whip for 1.0. It used to be a PL4 weapon. Whips made before the change became the Abysmal Whip, and the Masterwork recipe was moved to the Umbral Sands.
Step 1: kill the Abyssal Demon
The Abyssal Demon is a power level 4 boss with 6,250 health and a weakness to Slash. It has 4 spawns across Fractured Plains, Bloodblight Swamp and Whispering Swamp (see it on the map).
What it drops:
Study the Abyssal Remains to unlock the Abysmal Whip recipe. You need one Abyssal Spine per whip, so expect a second kill or more if the 45% roll misses.
Step 2: craft the Abysmal Whip
Blacksmith’s Bench, 100 Artisan XP:
Swamp Weed grows in 26 spots. Swamp Tar drops from Putrid Rats (1 each) and the Plague King (3), and turns up in world chests.
Step 3: upgrade to the Abyssal Whip
Jagex’s 1.0 notes say the Masterwork recipe is “found in the Umbral Sands”. The Abyssal Whip rework post adds that it sits “in the shadow of the Burning Spire”. Our game data doesn’t record the unlock point. The wiki puts it at a dragonkin statue in the lava directly north of the Fight Cave entrance: interact with it while wielding the Abysmal Whip.
Blacksmith’s Bench, 100 Artisan XP:
Demonic Oil
Brewing Cauldron: 6 Necrotic Bonemeal + 3 Vile Ashes + 1 Glass Vessel makes 1 oil. Six oils take 36 Necrotic Bonemeal, 18 Vile Ashes and 6 Glass Vessels.
Scorch Leather
Tannery or Advanced Tannery: 1 Draconic Leather + 2 Kalphite Shell + 1 Acrid Adhesive makes 1. Six take 6 Draconic Leather, 12 Kalphite Shell and 6 Acrid Adhesive.
Cursed Essence
Stormpact Demons in the Grand Hall drop 1 to 2 every kill. Ash Piles hold 2 to 3 more, so the demons you kill for Vile Ashes cover most of this.
Dragonstone
Mine Adamantite deposits (118 in the Umbral Sands: Dunes of Uzzer, The Burning Spire, Manafem Plains, Alcarrid Oasis) or Runite deposits (28).
The recipe calculator adds the whole tree up for you.
