Best Slayer Tasks OSRS for XP and Profit in 2025

Slayer in Old School RuneScape (OSRS) is a fan-favorite skill, blending combat training with lucrative rewards. Whether you’re grinding for level 99 or chasing gold pieces (GP), choosing the right Slayer tasks can make all the difference. This guide dives into the best Slayer tasks for experience (XP) and profit, optimized for efficiency in 2025. We’ll cover task requirements, strategies, and tips to maximize your gains, tailored for mid- to high-level players.

Slayer isn’t just about killing monsters—it’s a strategic skill that boosts combat XP, unlocks unique monsters, and fills your bank with valuable loot. By picking tasks that align with your goals (XP, GP, or both), you can optimize your time in Gielinor. The best tasks depend on your Slayer level, combat stats, and gear, but they share traits: high XP rates, valuable drops, or multi-combat areas for efficient kills.

Key Factors for Choosing Slayer Tasks

• XP Rates: Tasks like Nechryaels and Smoke Devils offer high Slayer XP per hour, especially with burst or barrage spells.
• Profitability: Monsters like Gargoyles and Skeletal Wyverns drop alchables and rare items, boosting GP per hour.
• Efficiency: Multi-combat areas and cannon-friendly tasks speed up kills, saving time.
• Slayer Level Requirements: Higher levels unlock better tasks, like Cerberus at 91 Slayer.

Below are the best XP-focused tasks, ideal for players with 70+ Slayer and decent combat stats.

Smoke Devils (93 Slayer)

Smoke Devils in the Smoke Devil Dungeon are the kings of Slayer XP, offering up to 100,000 XP per hour when barraging.
