Best Slayer Masters for XP
Duradel (100 combat, 50 Slayer) is the best master for pure XP. He assigns high-level tasks like Abyssal Demons, Nechryael, Gargoyles, and Dust Devils. Nieve/Steve offers nearly identical tasks and is located in the Gnome Stronghold. For mid-levels, Chaeldar (70 combat) in Zanaris provides solid tasks after Lost City quest completion.
Best Slayer Tasks for GP
The most profitable tasks are boss variants: Alchemical Hydra (95 Slayer) averages 3-5M GP/hr,Cerberus (91 Slayer) drops Primordial/Pegasian/Eternal crystals for 2-4M/hr, andKraken (87 Slayer) is extremely AFK with good consistent profit. Regular tasks like Gargoyles (75) and Abyssal Demons (85) provide 600k-1.2M/hr from alchables and rare drops.
Slayer Block List Strategy
Your block list should target common, low-XP tasks from your chosen master. With Duradel, prioritize blocking Hellhounds, Black Demons, Greater Demons, Fire Giants, and Spiritual Creatures. Each master has different task weights, so check your specific master's task list and block the worst offenders that you see frequently.
Gear Progression
Start with a Black Mask at 58 Slayer (imbue it at Nightmare Zone) for the critical damage boost. Upgrade to a Slayer Helmet (i) which works for all three combat styles. For melee, progress from Rune → Dragon → Barrows → Bandos. Ranged uses Black d'hide → Armadyl with Blowpipe/Bowfa. Magic users want Mystic → Ahrim's → Ancestral with Trident or Sang Staff.
Cannon and Burst/Barrage Methods
Dwarf Multicannon is essential for fast XP on multi-combat tasks. It costs ~200-300k/hr in cannonballs but can double your XP rates. Best tasks: Dagannoths, Kalphites, Suqahs, Smoke Devils.Bursting/Barraging in the Catacombs of Kourend on Dust Devils, Nechryael, and Bloodvelds provides 70k-90k+ Slayer XP/hr plus great Magic XP.
Slayer Point Unlocks
First unlock: Bigger and Badder (150 points) for superior slayer encounters (15-25% more XP). Second: Slayer Rings (300 points) for unlimited teleports. Third: Broader Fletching (300 points) to make Broad Bolts for cheap Ranged training. Then save points for blocking bad tasks. Wilderness Slayer with Krystilia awards 25 points per task for fast point farming (but brings PK risk).
Common Mistakes to Avoid
- •Not using Slayer Helmet — this is a 16.67% DPS increase, absolutely essential
- •Doing every task instead of skipping/blocking bad ones — efficiency matters
- •Poor inventory management causing multiple bank trips per task
- •Walking instead of teleporting — use house teleports with mounted jewelry
- •Ignoring superior monsters — these give massive XP bonuses
- •Using wrong combat style for the task (magic on high magic defense monsters, etc.)
