Best Demons to Use Arclight on in Old School RuneScape

In Old School RuneScape (OSRS), the Arclight is a standout weapon for slaying demonic creatures, thanks to its powerful demonbane properties. Upgraded from Darklight using ancient shards in the Catacombs of Kourend, this weapon boasts a 70% boost in accuracy and damage against demons, making it a go-to choice for specific encounters. With a requirement of 75 Attack to wield, Arclight shines in scenarios where demonic foes dominate. This guide dives into the best demons to target with Arclight, helping you maximize its potential for Slayer tasks, boss fights, and efficient grinding. Whether you’re tackling Slayer assignments or chasing loot, knowing where to wield Arclight can make all the difference.

Arclight’s demonbane passive effect gives it an edge over many high-tier weapons when fighting demons. Unlike general-purpose weapons like the Abyssal Whip, Arclight’s 70% accuracy and damage increase makes it best-in-slot (BiS) for certain demonic enemies. Its special attack, Weaken, consumes 50% special attack energy to reduce a demon’s Strength, Attack, and Defence by 10% + 1, stacking additively with multiple hits. This makes prolonged fights easier, especially against tougher foes. However, Arclight uses charges (up to 10,000 max), so strategic use is key to avoid reverting it to Darklight. Below, we explore the top demons where Arclight’s power truly shines.

Understanding Arclight’s Mechanics

Before diving into specific demons, it’s worth noting how Arclight works. Each successful hit consumes one charge, except for special attacks, and you’ll need ancient shards to recharge it. The weapon’s +70 Slash Attack bonus and fast attack speed make it ideal for Slayer and bossing, but its effectiveness depends on the target being a demon. Some creatures, like Duke Sucellus, have partial resistance (30%), reducing Arclight’s bonus to 49%. Knowing which demons are fully vulnerable ensures you get the most out of this weapon.

Top Demons for Arclight in Slayer Tasks

OSRS Arclight

Slayer tasks are a prime opportunity to wield Arclight, as many demonic creatures appear in assignments. These tasks often involve high-combat demons, and Arclight’s demonbane boost speeds up kills while conserving resources. Here are the best Slayer-assigned demons to use Arclight against.

Abyssal Demons

Abyssal Demons, requiring 85 Slayer, are a staple for high-level players chasing profit and experience. Found in the Slayer Tower, Catacombs of Kourend, and Abyssal Area, they drop valuable items like the Abyssal Whip and Abyssal Dagger. Arclight’s 70% damage boost makes it more effective than alternatives like the Abyssal Tentacle, cutting down kill times significantly. In the Catacombs, you can also farm ancient shards to recharge Arclight, making it a sustainable choice.

Greater Demons

Greater Demons (level 92) are a common Slayer task, appearing in places like the Brimhaven Dungeon and Catacombs of Kourend. While their loot isn’t as lucrative as Abyssal Demons, Arclight makes quick work of them, especially in multi-combat areas like the Catacombs where you can aggro multiple at once. Their relatively low Defence means Arclight’s boosted accuracy isn’t strictly necessary, but the damage increase speeds up tasks.

  • Combat Level: 92
  • Location: Catacombs, Brimhaven Dungeon
  • Why Use Arclight: Efficient for quick task completion

Black Demons

Black Demons, with a combat level of 172, are beefier targets found in the Taverley Dungeon, Catacombs, and Edgeville Dungeon. They’re weak to Arclight, and their high hitpoints make the weapon’s damage boost particularly valuable. In the Catacombs, safespotting with Arclight is viable, letting you conserve supplies while racking up kills. They also drop ancient shards, supporting Arclight’s upkeep.

  • Combat Level: 172
  • Location: Catacombs, Taverley Dungeon
  • Why Use Arclight: High hitpoints benefit from damage boost

Bosses Where Arclight Excels

Beyond Slayer tasks, Arclight is a top pick for demonic bosses. These encounters often demand high DPS, and Arclight’s demonbane effect can outshine even tier-80 weapons like the Blade of Saeldor in specific scenarios. Here are the demonic bosses where Arclight is a game-changer.

K’ril Tsutsaroth (Zamorak GWD)

K’ril Tsutsaroth, the Zamorakian general in the God Wars Dungeon, is a prime target for Arclight. As a demon, he takes full advantage of the 70% accuracy and damage boost, making Arclight BiS for solo and small-team setups. His high Defence and hitpoints mean the Weaken special attack can soften him up over time, reducing incoming damage from his melee attacks. However, you’ll need to manage charges carefully for extended trips.

Skotizo

Skotizo, a level 321 demon in the Catacombs of Kourend, is accessible via dark totems. Arclight is the go-to weapon here, shredding through Skotizo’s health with its demonbane boost. The fight is relatively short, so charge consumption isn’t a major concern, and Skotizo drops ancient shards, potentially offsetting costs. The Weaken special attack helps manage summoned minions by lowering their stats, making the encounter smoother.

Demonic Gorillas

Demonic Gorillas, found in the Crash Site Cavern after Monkey Madness II, are a hybrid challenge requiring melee, ranged, and magic switches. As demons, they’re highly susceptible to Arclight during melee phases, where it outperforms most weapons due to the 70% boost. However, switching to Arclight can slow DPS if you’re not adept at gear swaps, so it’s best for players comfortable with multi-style combat. Their shard drops make them a good spot to farm Arclight charges.

Honorable Mentions for Arclight Use

While the above demons are the cream of the crop, a few others deserve a nod for Arclight’s effectiveness. These are less common but still viable targets, especially if you’re looking to mix up your gameplay or tackle specific content.

Nechryael

Nechryael (level 115) in the Slayer Tower and Catacombs spawn Death Spawns, which can be annoying without high DPS. Arclight’s speed and damage boost help clear them quickly, though their Defence is low enough that other weapons like the Whip are also viable. Use Arclight here if you have spare charges and want faster kills.

Tormented Demons

Introduced with While Guthix Sleeps, Tormented Demons in the Ancient Guthixian Temple are greater demons vulnerable to Arclight. They require multiple combat styles, but Arclight shines during melee phases, especially since they drop tormented synapses for crafting Emberlight, Arclight’s upgraded version. Their high Defence makes the demonbane boost worthwhile.

Tips for Using Arclight Effectively

To get the most out of Arclight, you need to use it wisely. Here are some practical tips to optimize its performance and manage its charges:

  • Conserve Charges: Avoid using Arclight on non-demons or demons with low hitpoints, like Lesser Demons, where a Whip is sufficient.
  • Farm Shards: Prioritize Catacombs tasks (e.g., Abyssal Demons, Black Demons) to collect ancient shards for recharging.
  • Special Attack Timing: Use Weaken early in boss fights like K’ril or Skotizo to reduce their stats, making the rest of the fight easier.
  • Gear Synergy: Pair Arclight with strength-boosting gear (e.g., Bandos armor, Primordial Boots) to maximize DPS.
  • Consider Emberlight: If you’ve completed While Guthix Sleeps and have 74 Smithing, upgrade to Emberlight for a non-degrading demonbane weapon with a stronger special attack.

When to Skip Arclight

Arclight isn’t always the best choice. For example, Duke Sucellus’s 30% demonbane resistance makes other weapons like the Shadow or Tumeken’s Warden more efficient. Similarly, low-level demons like Lesser Demons don’t justify charge usage. If you’re low on shards or plan to fight bosses like the Abyssal Sire (where Arclight isn’t BiS), consider alternatives like the Rapier or Whip.

Arclight is a niche but powerful tool in OSRS, transforming demon-heavy encounters into manageable fights. By focusing on high-value targets like Abyssal Demons, K’ril Tsutsaroth, Skotizo, Demonic Gorillas, and Tormented Demons, you’ll make the most of its demonbane prowess. Plan your charges, leverage the Weaken special attack, and pair it with optimal gear to dominate demonic foes. Whether you’re grinding Slayer or chasing boss loot, Arclight is your key to slicing through Gielinor’s darkest creatures with ease.
