Arc Blade

Version 0.29: This article may not be up to date for the latest stable release of Crawl.

A blade somehow crafted from pure electricity. It arcs wildly between the wielder and their foes as it strikes. It occasionally unleashes powerful arcs of lightning upon striking a foe. These may arc to other adjacent creatures (including the wielder, but dealing reduced damage to them) before grounding out.

Desirability

The arc blade deals a little more damage than a +9 demon blade of electrocution, making it a strong weapon in its own right. Discharges will arc out to other adjacent monsters, which is particularly effective against crowds, and doubly effective against crowds stuck in a hallway, as you can hit them without being hit back.

However, Static Discharge deals no damage against electric-resistant or immune targets. Against them, the arc blade is no better than a +8 rapier. Carrying an alternate weapon is advised, as rElec is fairly common in Zot and extended.

The arc blade has an anti-synergy with most allies, as they are not exempt from the discharges. The game will prompt you whenever an ally could be hit.
