Version 0.28: This article may not be up to date for the latest stable release of Crawl.
Dramatically increases the user's regeneration of magical power for a duration that increases with Invocations skill.

Channeling is the act of restoring MP to a character. There are two types:

Active Channeling

Channel Magic is an ability that allows worshipers of Sif Muna to restore MP much more quickly. You gain this ability at * piety. The ability's success rate starts at 60%, increased by 4% for each of your levels of Invocations and additionally by piety/25%.

The amount of MP recovered is 3-5 per turn for 4 + random2avg(2 * Invocations / 3) turns, which is roughly equal to 4 to 4 + 0.66 * Invocations turns.

In addition, the spell Sublimation of Blood converts HP into MP, using a different mechanic.

Passive Channeling

The orb of energy and staff of Wucad Mu allow you to passively channel energy. The latter counts are two sources of channeling.

When casting a spell while wielding a source of passive channeling you have an Sources * Evocations / 54 chance of regaining the MP used in the spell. Each time this happens, you have a 1 / (Evocations - MP cost)^sources chance of either being confused for 1 + 1d4 turns or losing 1-5 intelligence.

History

  • Prior to 0.28, different sources of passive channeling did not exist (thus, they could not stack)
  • Prior to 0.26, you could actively channel magic by using a staff of energy Evocations skill. In 0.27, the staff of Wucad Mu's active channeling was removed, too. Both staves' channeling would decrease in success as your MP decreased.
  • Prior to 0.24, Channel Magic was Sif Muna's *** ability.
  • Prior to 0.19, Channel Magic was not based on a duration. With each use, it recovered a small amount of MP, depending on Invocations skill, and cost hunger but no piety. It was also referred to as Channel energy.
