Old School RuneScape: How to Profit from Nieve Slayer Tasks

To turn Nieve into a profitable Slayer master in Old School RuneScape, you must be at least combat level 85, filter out resource-draining assignments, substitute bosses for standard monster tasks, and use area-of-effect Magic in the Catacombs of Kourend. Managing your task list and supplies properly ensures that routine Slayer training produces consistent gold instead of draining your coin stack.

Setting Up Your Block and Skip List

Nieve assigns a pool weighted toward high-tier Slayer monsters. Tasks with high assignment weights that yield poor loot or drain expensive supplies should be permanently blocked. Low-weight, unprofitable tasks should be skipped using Slayer points.

Unlock the "Bigger and Badder" reward early. This perk enables superior Slayer monster variants to spawn during tasks, granting high combat experience and the chance at valuable unique drops like the Imbued Heart and Eternal Gem.

Category	Monster Assignments	Action	Value Factor
High Priority (Kill)	Gargoyles, Nechryaels, Abyssal Demons	Full clear	High-tier alchables, rune equipment, raw coins
Boss Alternative	Hellhounds, Cave Kraken	Fight boss variant	Cerberus crystals, Kraken tentacles, steady runes
Permanent Block	Spiritual Creatures, Metal Dragons (Iron/Steel), Suqahs	Add to block list	High weight, low drop value, heavy supply usage
Quick Skip	Scorpions, Brine Rats, Waterfiends, Trolls	Cancel assignment	Low weight, poor profit-to-time ratio

Note: If you have level 91 Slayer, keep Hellhounds off your block list so you can kill Cerberus.

Swapping Tasks for Boss Encounters

Boss variants offer far higher average gold per hour than basic monster packs:

Cerberus (Level 91 Slayer): When assigned Hellhounds, kill Cerberus to target high-value drops, including Primordial, Pegasian, and Eternal crystals.
Kraken (Level 87 Slayer): Replace standard Cave Kraken tasks with the Kraken boss for unnoted runes, raw coins, and Kraken tentacles at low supply costs.
"Like a Boss" Unlock: Purchasing this Slayer unlock allows Nieve to assign dedicated boss encounters (such as Vorkath, Zulrah, and the King Black Dragon) in quantities of 3 to 35 kills.

Always fight these targets with an imbued Slayer Helmet or Black Mask (i), which provides a 16.67% boost to Melee accuracy and damage, alongside a 15% boost to Ranged and Magic accuracy and damage.

Bursting and Cannon Resource Management

High profits rely on balancing rune and ammunition costs against drop volume:

Bursting in the Catacombs of Kourend: For multi-target tasks like Dust Devils and Nechryaels, use Ancient Magicks (burst or barrage spells). While Blood and Death runes require an upfront investment, the volume of coin drops, runes, and High Alchemy equipment outweighs the spell costs.
Selective Cannon Usage: The Dwarf Multicannon speeds up single-target tasks like Bloodvelds and Fire Giants in the Stronghold Slayer Cave, but cannonballs cut deeply into profit. If your goal is pure gold generation rather than fast experience, skip the cannon on low-yield tasks and fight with Melee gear.

Managing Inventory and Reducing Supply Costs

Frequent bank runs reduce your effective hourly profit. Carry specialized storage items and utility spells on every assignment:

Rune Pouch: Carry Nature runes and Fire runes to cast High Alchemy on metal armor, warhammers, and battleaxes directly on-site.
Herb Sack and Gem Bag: Store up to 420 grimy herbs and collect uncut gems dropped by monsters like Gargoyles to preserve free inventory slots for high-value loot.
Bonecrusher: Carry this item in the Catacombs of Kourend to passively restore Prayer points upon monster deaths, reducing the need for expensive Prayer potions.
Defensive Gear: Use Protection Prayers paired with high Prayer bonus armor (such as Proselyte) on heavy-damage tasks to avoid consuming expensive food.
