Aquinites are a high-level Slayer monster in Old School RuneScape (OSRS) that offer substantial Slayer experience and unique drops. To efficiently tackle these creatures, there are several prerequisites and strategies players with OSRS gold should follow to maximize both XP and loot. This guide will walk you step by step through preparation, travel, combat, and rewards when facing Aquinites.

Requirements
Before engaging Aquinites, players need to meet the following requirements: the completion of the Regicide quest, level 78 Slayer, level 73 Sailing, access to your own player-owned boat, and 80 Slayer points to unlock the Lord assignment, which allows you to receive Aquinites as a task. While not mandatory, completing the Song of the Owls quest can significantly ease transportation across the islands.

Traveling to Yinsdale Island
Aquinites reside in a cave on Yinsdale Island. The most common route begins by chartering a ship to Port Tyras for 3,200 coins, ideally from Port Sarim. Upon arrival, summon your player-owned boat and head northwest until you locate the Gwenneth Glide portal. Steering through this portal, continue slightly northwest to spot two ice walls emerging from the ocean. Navigate between these walls, then proceed east to reach Yinsdale Island.
Upon arrival, players can utilize a shortcut on the eastern side of the island if Song of the Owls has been completed. This rowboat shortcut requires 50 Construction, a saw, a hammer, eight camper planks, and 10 swamp paste. However, the shortcut is only accessible from the east side, so the initial ship method is still necessary to reach the island for the first time.
For an alternative route, teleport to Pri using an internal teleport crystal. Head north to the city gates, pass through, and then move northwest towards the robo. Interacting with the robo will transport you directly to the island. Once on Yinsdale, head north to the cave entrance where the Aquinites reside.

Combat Strategy
Inside the cave, the Aquinites are primarily found in the southern section. These monsters have 180 hitpoints (HP) and attack using Magic, dealing a maximum hit of 18. They are weak to stab attacks, making weapons with a stabbing option optimal.
Aquinites possess a unique mechanic known as the “law,” which appears on their heads as a spoon-like object. Using a slashing weapon to sever this law reduces their stab defense from 60 to 10, effectively doubling the damage potential for stab weapons. This step is optional but highly recommended for players aiming to maximize Slayer XP per hour. Notably, landing a zero damage hit while severing the law still counts, so players can switch back to a stab weapon immediately afterward.

Loot and Rewards
Regular Aquinites provide 180 Slayer XP per kill, and their average drop is valued at approximately 3,400 coins. Players can expect drops such as big bones, a variety of frags, cannonballs, seeds, coins, and water battle staffs. A particularly notable drop is the Aquinite Tendon, which has a 1 in 3,500 chance off task and 1 in 750 on a Slayer task. Tendons are a collection log item and currently trade around 3.8 million coins. Other potential drops include long and curved bones as well as hard clue scrolls, though the exact drop rate for the latter is currently unknown.

Superior Aquinites
Players with the “Bigger and Better Slayer” upgrade have a chance of encountering Elder Aquinites, a superior version of the standard monster. Elder Aquinites have 400 HP, are weak to stab attacks, and provide 4,200 Slayer XP per kill. Their loot mirrors regular Aquinites but includes four unique items: the Dust and Mist battle staffs, an internal Slayer gem (worth roughly 8.2 million coins), and the Imbued Heart, valued at around 113 million coins. These rare drops make targeting Elder Aquinites extremely rewarding for high-level players.

Conclusion
Killing Aquinites in OSRS is a rewarding Slayer task for players looking for high XP, rare drops, and a challenging combat experience. Preparation is key: ensure you meet the requirements with RS gold for sale, plan your travel carefully, and understand the combat mechanics, particularly the “law” system. Whether you are farming regular Aquinites or hunting superior Elder Aquinites, this guide provides the essential steps to maximize efficiency, loot, and overall Slayer gains.
