Jewel of the Sun OSRS A Comprehensive Guide to Unlocking Its Power

In the vast world of Old School RuneScape (OSRS), the Jewel of the Sun stands out as a coveted reward from the Tombs of Amascut (ToA) raid. This untradeable jewel, when attached to the Keris Partisan, transforms it into the Keris Partisan of the Sun, a powerful weapon with unique abilities tailored for ToA. Whether you’re a seasoned raider or a newcomer to OSRS, this guide will walk you through everything you need to know about the Jewel of the Sun, from obtaining it to mastering its use in high-level raids.

The Jewel of the Sun is an untradeable item dropped exclusively in the Tombs of Amascut raid. It’s one of three jewels (alongside the Jewel of the Breach and Jewel of the Shadows) that can be attached to the Keris Partisan, a one-handed spear requiring 80 Attack to wield. When combined, the Jewel of the Sun creates the Keris Partisan of the Sun, which boasts a special attack called Tumeken’s Light and passive effects that make it a game-changer in ToA.

Key Features of the Jewel of the Sun

• Untradeable: You must earn it through ToA completions.
• Attachment: Combines with the Keris Partisan to form the Keris Partisan of the Sun.
• Special Attack: Tumeken’s Light heals the player, cures ailments, and restores stats.
• Raid-Specific: Its abilities are exclusive to ToA, making it a must-have for high-invocation runs.

How to Obtain the Jewel of the Sun

Securing the Jewel of the Sun requires diving into the challenging Tombs of Amascut raid. The drop rate and optimal strategies for obtaining it are critical for players aiming to add this jewel to their arsenal.

Drop Rate and Bad Luck Mitigation

The base drop rate for any Keris Partisan jewel is approximately 1/60. If you’re missing one or more of the three jewels, the game guarantees you’ll receive an unobtained one upon a successful jewel roll, effectively making the rate 1/120 for two missing jewels or 1/60 for one. Additionally, a bad luck mitigation mechanic increases the drop rate from 1/180 to 3/180 (1/60) as your raid completion count reaches 270, scaling linearly.

For example, a player at 181 completions has a 3.9% chance per raid to obtain the Jewel of the Sun if it’s their only missing jewel. Reddit discussions highlight players going as high as 260 raids without the jewel, emphasizing the importance of persistence.

Optimal Raid Strategies for Jewel Farming

To maximize your chances of getting the Jewel of the Sun, consider these strategies:

• Run 150 Invocation Raids: These balance speed and loot potential, with purples having a 49/50 chance to reroll into a jewel if under 150 invocation.
• Entry Mode for Speed: Entry mode (0 invocation) offers faster completions (20-25 minutes) but sacrifices major unique drops.
• Mass Raids: Join 8-man raids at 300-400 invocation for faster clears and more rolls, especially in free-for-all (FFA) worlds.
• Drop Switches: Bring fewer switches (e.g., skip assembler or tassets) to carry more supplies, ensuring you survive higher invocations.

According to Reddit, spamming 150s is ideal for most players, as it avoids the regret of a jewel replacing a rare purple drop.

The Keris Partisan of the Sun Abilities and Uses

Once you’ve obtained the Jewel of the Sun, attaching it to the Keris Partisan unlocks the Keris Partisan of the Sun, a weapon with unique mechanics that shine in ToA.

Tumeken’s Light Special Attack

The special attack, Tumeken’s Light, is the centerpiece of the Keris Partisan of the Sun. It consumes 50 prayer points and 75% special attack energy to deliver the following effects:

This makes Tumeken’s Light a lifesaver in high-invocation runs, particularly during phases like the Wardens’ skull phase, where players can overheal to survive intense damage. OSRS Wiki notes its utility in replacing brews, allowing players to carry more prayer potions or restores.

Passive Effects in ToA

The Keris Partisan of the Sun has two ToA-exclusive passive effects:

1. 25% Accuracy Boost: Increases accuracy against targets below 25% health, ideal for finishing off bosses like Zebak or Baba.
2. Kalphite/Scabarite Bonus: Retains the Keris Partisan’s 33% damage bonus and 1/51 chance for triple damage against kalphites and scabarites, useful in Kephri’s room.

These effects make the weapon versatile, though its special attack is the primary reason players seek the Jewel of the Sun.

Why the Jewel of the Sun Is Essential for ToA

The Jewel of the Sun is a game-changer for high-level ToA runs, particularly at 400+ invocations or expert modes like Insanity. Its ability to replace brews and restores allows for more aggressive inventory setups, while Tumeken’s Light can turn the tide in clutch moments.

Impact on High-Invocation Raids

At higher invocations, mechanics like Not Hardly Numb and Dehydration punish small mistakes harshly. The Keris Partisan of the Sun’s special attack mitigates these by providing a full heal and stat restore, reducing reliance on supplies. Players on forums report using it during the Wardens’ P1 phase to clear pillars faster or during P3 to overheal against skulls, comparing its utility to a “mini Ambrosia.”

Is It Necessary for Lower Invocations?

For raids below 300 invocation, the Jewel of the Sun is less critical. Reddit users suggest focusing on dealing damage with special attacks from weapons like the Voidwaker or BGS at lower levels, as brews are sufficient for survival. However, as you push toward 350-400 invocations, the jewel becomes nearly essential for consistent clears.

Tips for Maximizing the Jewel of the Sun’s Potential

To get the most out of the Keris Partisan of the Sun, follow these practical tips based on community insights and raid mechanics.

Inventory Management

Optimize your inventory to leverage the jewel’s healing capabilities:

• Replace 1-2 brews with prayer potions or restores, as Tumeken’s Light covers healing needs.
• Use adrenaline potions to chain special attacks during critical phases like Wardens’ P1.
• Bring a rune pouch for blood burst/barrage in rooms like Baba’s to conserve supplies.

Timing Tumeken’s Light

Use the special attack strategically:

• Wardens’ P3: Overheal before the skull phase to tank hits.
• Kephri: Heal after scarab swarms to restore stats and run energy.
• Zebak: Use during enrage phases to recover from high-damage attacks.

Skill and Gear Synergy

While the Jewel of the Sun is powerful, it shines with proper gear and skill:

• Gear: Pair with high-damage weapons like Bowfa or Fang for DPS, using the Keris for utility.
• Skills: High combat stats (90+ Attack, Strength, Ranged) and prayer (70+ for Piety) maximize its effectiveness.
• Practice: Master ToA mechanics like butterfly Akkha or red X Baba to minimize damage taken, reducing reliance on the special attack.

In conclusion, the Jewel of the Sun is a must-have for serious ToA raiders in OSRS. Its acquisition may test your patience due to RNG, but the Keris Partisan of the Sun’s Tumeken’s Light and passive effects make it a cornerstone of high-invocation strategies. By optimizing raid setups, timing its special attack, and refining your skills, you’ll turn this radiant jewel into a beacon of success in the Tombs of Amascut. Happy raiding!
