Distortion

Version 0.28: This article may not be up to date for the latest stable release of Crawl.

It warps and distorts space around it. Unwielding it can cause banishment or high damage.

Distortion is a brand that any melee weapon may have. Distortion weapons bend and tear the fabric of space-time, and generate a variety of effects when they hit:

Chance	Effect
35%	The target takes an additional 1-7 damage
25%	The target takes an additional 3-26 damage (14.5 on average, low variation)
20%	The target blinks
5%	The target is banished to the Abyss
15%	Nothing happens

Conversely, unwielding a weapon branded with distortion or casting Excruciating Wounds on it also causes dangerous effects to the player:

• 50% chance: teleport to random monsters on the floor
• 25% chance: inflict significant magical contamination
• 25% chance: banished to the Abyss

Followers of Lugonu are protected from these effects. Pious followers of Lugonu can have a weapon branded with distortion once per game, guaranteeing them access to the brand's effects.

Strategy

• Since the brand deals irresistable damage independent from your weapon, it works best on a fast weapon with low base delay. However, it might blink ranged enemies away from you, or banish foes with their equipment.
  • The 5% chance for a practical OHKO is always relevant; it can even banish otherwise hex-immune foes like the Hell lords, though any banished enemy might appear in the Abyss later on.
• If you intend to switch between weapons without Lugonu, you almost certainly don't want to deal with a distortion weapon's guaranteed backlash effects.
  • Positive effects of unwielding include a very last-ditch teleport (when confused) and Abyss access (when other areas are much, much harder). Getting sent to the Abyss this way may cause you to enter a deeper floor, though.
• Be careful about the blinking effect. It gives you no message when it occurs, suddenly leaving you with empty space where that monster used to be. You may move into an unintended spot very quickly.
• When facing another creature wielding a weapon of distortion (or one with a naturally distortion-branded attack, like spatial vortices), do your best not to let them into melee range if you can at all help it.
  • Certain uniques are likely to possess distortion weapons: Psyche, Sonja, and The Enchantress.
• Casters that like to keep enemies away from them may find a distortion branded polearm quite useful, since its blink effect creates space between you and monsters. It's wise to train at least a little skill so you can hit at 1.0 delay.
• Despite giving full experience, Banish does not count as a kill; most gods won't reward you, and effects like Powered By Death won't activate.

History

• Prior to 0.27, Distortion was an extremely punishing brand for those who wield-ID'd items.
• In 0.26, the chance to banish was reduced from 10% to 5%. Also, banishment also provided half experience.
• Prior to 0.25, distortion weapons had a chance of teleporting monsters away from you when attacking. They also caused Translocations miscast effects when unwielded.
• Prior to 0.19, distortion weapons could sometimes heal blink frogs (including the unique blink frog Prince Ribbit), who were immune to all of the effects of the distortion brand. Additionally, the spell Warp Weapon existed, which could apply a temporary distortion brand to your weapon.
• Prior to 0.15, rebranding a distortion weapon (e.g. by a Scroll of brand weapon) caused a distortion effect.
• Prior to 0.14, followers of Lugonu were not protected from the effects of unwielding a distortion weapon.
• Prior to 0.12, this brand was safer when found on sharp weapons, since blunt weapons didn't allow butchering corpses.
