Bolt spells

Version 0.30: This article may not be up to date for the latest stable release of Crawl.

The Bolt spells are a series of spells which all function similarly, hitting multiple targets along its line of fire. Although there is some variance in their damage output and range, they all behave in nearly the same fashion.

Players no longer have access to any "traditional" bolt spell in their spell library, though bolts are still accessible through other ways.

Player-Castable

Almost all "bolt" spells have been removed from player libraries, although there are a few spells that create bolts:

• Plasma Beam
• Shock
• Starburst

Evocable

Thunderbolt

• Available through a lightning rod
• Power determined by Evocations
• Consecutive zaps increases strength and changes behavior of the bolt
  • Aiming for a different target creates a wide spray that covers the area between the previous bolt and the current bolt
• Deals electricity damage; deals less damage when spread over a wide area
• Range 5

History/Trivia

• In 0.30, Lightning Bolt was made monster and Makhleb only, removing the last player-castable bolt spell.
• In 0.29, the wand of quicksilver and wand of light were added as alternatives for the wand of acid. Each game can have only one "bolt" wand type now.
• In 0.28, Bolt of Magma was made monster and Makhleb only.
• In 0.27, Makhleb's Major Destruction was made explicitly bolt-only.
• Prior to 0.26, most beam spells (except for Shock and Lightning Bolt) had their range decreased by 1 for each target they hit.
• Most bolt spells were removed from player's libraries in the positional magic update of 0.25; Bolt of Fire, Bolt of Cold, Bolt of Draining, and Venom Bolt were removed.
• Prior to 0.21, the wand of lightning existed, which cast Lightning Bolt.
• Prior to 0.20, there were special evocable items called rods; the Rod of inaccuracy had a powerful but highly inaccurate bolt spell called Bolt of Inaccuracy, and the Rod of ignition could fire a special version of Bolt of Fire named Explosive Bolt.
• Prior to 0.18, there were wands of fire, cold, and draining, which cast their bolt spells with Evocations. The Rod of destruction, had a special bolt spell called Random Bolt. In their place, the wand of acid gave players access to Corrosive Bolt.
• 0.17 added Corrosive Bolt.
• Prior to 0.16, the Tome of destruction could fire a number of these bolt spells.
• Random Bolt was added in 0.14.
• The term 'bolt' did not always refer only to spells which can hit multiple targets in a line. Notably, the spell Iron Shot went through the names Bolt of Iron and Iron Bolt before being renamed Iron Shot to avoid confusion, and Throw Icicle was renamed from Ice Bolt for the same reason.
