Looking to maximize your coin stack in Old School RuneScape (OSRS)? Removing Slayer assignment obstacles and focusing on profitable creatures is key. This guide delves into strategies for obtaining the best GP per hour (GPH) from Slayer tasks through targeting rich monsters to pickaxe, alongside essential drops and rare rewards.

Understanding OSRS Slayer profitable monsters isn't merely about kill value; it's also about balance - balancing kill speed, summoning use, and available banking locations. Every training method has an optimal Slayer monster. Let's explore the best monsters to maximize your GPH.

Highest GP/Hr Slayer Creatures
The following creatures offer excellent GPH, considering all factors.

Abyssal Demons
Found in the Abyss, requiring at least 60 Slayer, these demons provide great GPH with consistent and high-value drops, including Signs of the Porter and mystical picks.

Using the Evaluate dropdown in the Grand Exchange to check drop prices, an Abyssal Demon can drop rare and valuable bones, along with mithril and adamant scimitars. With a Guinea Pig familiar, you'll also collect runes and feathers.
Blue Dragons
Blue Dragons, found in the Blue Dragon Cave (65 Slayer) or the Deserted Keep (70 Slayer), drop some of the best-valued items in the game, such as blue dragonhide and blue dragon bones.

With a Dragon Sword or higher, and tier 80+ ranged or melee gear, you can quickly dispatch these monsters, banking regularly with aInterface Setting set to "Max" - ideal for optimal range and melee abilities.
Top GP Drops for Parts
Some Slayer monsters offer excellent GP when picked apart for specific parts. It's crucial to collect these drops for later use or trade.

Kraken
At 87 Slayer, these late-game monsters offer an array of valuable drops. Collective unique gameplay elements and collectible tentacles, eyes and other parts, can be sold or used in PVM setups.








At 70+ range or higher, you can safely camp essentially, accompanied by a familiar for banking assistance. Ranging with High-Level Swordfish, the rotation is Corrode -> Powerful Blast -> Mystic might (or Superheat Form) -> THerchard and repeat.
Bryophyta
Discovered in the Lava Maze at level 85 Slayer, inhabitants pose strong combat levels and moderate hitpoints. The sought-after Miasmic Sludge can be collected and sold for high profits.
Offering reasonable drops, such as unboding bones and green capes, targeting Bryophyta becomes more feasible with high-level melee gear. Additionally, wearing Miasmic robes boosts Slayer xp, making them an excellent long-term investment.
Whether targeting high-kill speed monsters like Abyssal Demons or those with top-dollar GP drop value like Kraken and Bryophyta, mapping out an efficient Slayer strategy involves a perfect blend of various factors. Keep adjusting your approach based on GP values, combat capabilities, and your bank's inventory. Always consider your Slayer assignments, with a smart mix of profitable creatures leading to a swelling coin stash.
