How to Get the Arclight in OSRS
Arclight is one of the most powerful demonbane weapons in Old School RuneScape, requiring level 75 Attack to wield. It is an upgraded version of Darklight and is especially effective against demonic monsters, thanks to its passive bonuses and strong combat stats. Arclight is also a highly sought-after weapon due to its combination of speed, accuracy, and special attack utility, making it an essential tool for players who frequently engage in demon battles.

How to Obtain Arclight
To obtain Arclight, players must combine Darklight with three Ancient Shards at the altar in the center of the Catacombs of Kourend. This process consumes the shards and transforms Darklight into Arclight. If lost, the weapon can be reclaimed by speaking to Sir Prysin for 1,000 coins to retrieve Darklight and then upgrading it again with three more Ancient Shards at the altar.
Combat Stats of Arclight
Arclight’s effectiveness changes depending on whether it is charged or inactive. When inactive, it offers stronger strength bonuses but slower speed. Once charged, its slash accuracy rises significantly, while the weapon becomes faster and more precise.
Variant | Strength Bonus | Attack Speed | Slash Bonus | Notes |
|---|---|---|---|---|
Uncharged | +13 | 5 ticks (3.0s) | +16 | Higher strength, slower |
Charged | +8 | 4 ticks (2.4s) | +38 | Faster, very accurate |
Special Attack
Arclight retains Darklight’s special attack, Weaken, which costs 50% of the special attack energy bar. It reduces an opponent’s Strength, Attack, and Defence by 5% of their base level plus 1. Against demons, this effect is doubled to 10% + 2. Unlike the Dragon Warhammer’s multiplicative reduction, Arclight’s reductions are additive, making multiple successful uses of Weaken stack together effectively.
Mechanics and Passive Effect
Arclight has a unique passive effect that boosts accuracy and damage by 70% against demonic monsters. This includes enemies like Abyssal Demons, Black Demons, Greater Demons, and K’ril Tsutsaroth. An exception is Duke Sucellus, who only takes 30% of the usual demonbane bonus. Despite this, Arclight remains one of the strongest choices for demon-related content thanks to its enhanced output.

Charging Arclight
Arclight begins with 1,000 charges upon creation. Each Ancient Shard used to recharge it provides an additional 333 charges, or 1,000 charges if three shards are added at once. The weapon has a maximum capacity of 10,000 charges. Each successful hit consumes one charge, except for its special attack. When charges are depleted, Arclight becomes inactive and reverts to the weaker stat set until recharged.
Infusion and Upgrading
Each charge consumed also adds to Arclight’s infusion mechanic, with 10,000 charges representing 100% infusion. This infusion percentage is relevant when upgrading Arclight into Emberlight, which requires level 74 Smithing (alongside Duradel’s notes). Using a Tormented Synapse with a fully charged or infused Arclight allows players to upgrade it. Emberlight offers stronger combat stats and does not degrade.
