Spell noise

Version 0.16: This article may not be up to date for the latest stable release of Crawl.

Spell noise is the noise generated when casting spells.

How noise is determined

There is a casting noise that will be made at the caster's position.

A second source of noise is the spell itself. The noise will be made at the target's position. Some spells don't make any noise at all, like Bolt of Draining, and they end up with a noise of 0. For bolt spells, the noise is made at each square where it hits a monster, and the last square the spell reached even if it doesn't hit anything.

History

• In 0.30, the actual casting noise will be based directly on spell level; other than certain exceptions like Ensorcelled Hibernation, 1 spell level = 1 casting noise. The noise of the spell effect itself is unchanged.
• Prior to 0.16, noise used to be based directly on the spell level:
  • for Conjurations: spell level
  • for non-conjurations Poison Magic/Air Magic spells: spell level / 2 (rounded up)
  • for other spells: spell level * 3/4 (rounded up)
