Arc Blade

Version 0.30: 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

Against single targets, the arc blade has roughly the same damage as a normal rapier of electrocution (slightly weaker), making it a good weapon in its own right.

Compared to a normal weapon of electrocution, Static Discharge will arc out to monsters adjacent to the target, making it particularly effective against crowds. It's doubly effective against crowds stuck in a hallway, as you can hit them without being hit back. Unfortunately, the discharges will deal some slight damage to you (though this is greatly reduced by the rElec the blade provides).

Since the arc blade deals electric damage, you may want a different weapon against those resistant/immune to electricity.

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.
