Investing time in Old School RuneScape (OSRS) and tackling slayer assignments can indeed be profitable, with many slayer monsters yielding valuable rewards. But understanding these monsters' GP per hour (GP/hr) rates can help you optimize your grind and maximize your gains. So, let's dive into OSRS slayer monsters and explore their GP/hr potential.

Before we delve into specific monsters, let's briefly discuss factors affecting GP/hr. These include your combat level, gear, and, most importantly, the monster's drop table and drop rates. Remember, GP/hr is an average estimate, and actual results may vary. Now, let's explore different categories of slayer monsters and their approximate GP/hr.

High-Level Slayer Monsters (75+)
These monsters typically offer better drops, but require higher combat levels to defeat. Here are a couple of standout examples:

Abyssal Demon
The Abyssal Demon is a popular choice for high-level slayers. They drop valuable items like demonic skulls, mystic air batteries, and even 3rd age items. Expect approximately 200k-300k GP/hr from drops and 200k/hr from bones to peaches if you're using the prayer renewal setup.

They're also a great source of slayer points, so consider using an ear.extensions for extra slayer experience if you're not already tailoring to it.
Jad
The Jadbomb, or Jad, is a fearsome foe with significant loot potential. Her drops include high-level food, potions, weapons, and even a Rune platebody. With high hitpoints (500,000) and considerable range attacks, Jad requires a well-thought-out strategy. Expect around 300k-400k GP/hr.

Mid-Level Slayer Monsters (50-75)
These monsters are accessible to a broader range of players and still offer decent GP/hr. Let's look at a couple of options:
Gargoyle

The Gargoyle is a popular choice for mid-level slayers. They drop useful items like book of balance and opal/red topaz uncut. Expect around 150k-250k GP/hr, with the potential for higher figures if you receive a drop like dragon chainbody.
Consider using slayer's extend or super combat potions for better efficiency.








Mistral Dragon
The Mistral Dragon is another worthy consideration, with drops like dragon platelegs and dragon full helm. Expect around 200k-300k GP/hr, although this can vary significantly based on drops.
These dragons hit accurately in the magic combat style, so consider protecting against their blade spells and using shotgun or dwarf multicannon for efficient killing.
Remember, these are just estimates. Your actual GP/hr will depend on your gear, the specific drops you receive, and your combat efficiency. To optimize your slayer grind, experiment with different monsters, locations, and looting methods.
In OSRS, it's crucial to stay adaptable and tweak your strategies based on your progress and new discoveries. Keep exploring, keep learning, and above all, keep enjoying the grind. Happy adventuring!
