Obsolete: This article refers to an aspect of the game which has been removed. It is retained for historical reference only.
A crystal staff overflowing with magical energies, which can be channeled by a skilled wielder to allow them to cast spells without exhausting any of their own magical energies — at the risk of damaging the user's mind.

For the current version of this item, see crystal ball of Wucad Mu.

+9 staff

Channels MP (may refund the MP of spells cast by the wielder)

Mechanics

When casting a spell while wielding the staff of Wucad Mu[1], you have a 3 * Evocations / 108 chance of regaining the MP used in the spell (75% chance at 27 Evocations). This chance stacks with the chance from wielding an orb of energy -- see the Channeling page for more details.

Each time this happens, you have a 1 / (Evocations - MP cost) chance of either being confused for 1 + 1d4 turns or losing 1-5 intelligence.

Desirability

The staff of Wucad Mu[2] is most useful for characters that have invested heavily in both Evocations and magic. Evocations is required to actually get MP, while magic skill is required so that you can actually make use of mana. Many evocable items tend to be redundant with a good spell repertoire, so it's somewhat difficult to invest in both.

The staff of Wucad Mu does little to help those who have run out of MP entirely, as it only refunds a spell's MP cost. Regardless, the ability to cast your most powerful spells even a few more times can and will make a difference between victory and running dry mid-fight. Overall, it is a powerful item balanced by its fair share of drawbacks - assuming you're casting spells in the first place.

Ziggurat raiders have the high-level spells to cast and the XP to spare; they'll find few better items to wield for general use. While confusion is annoying for lichform players, a source of Clarity will block it entirely, while Intelligence drain will be cured near instantly.

Djinn do not use MP and cannot activate the staff of Wucad Mu, other than using it to bludgeon enemies as a plain +9 staff. By no means a main weapon, a non-Djinn could use this to finish off weakened enemies.

History

  • In 0.30, this item was replaced by the crystal ball of Wucad Mu. Also, channeling mechanics were changed between versions.
  • In 0.28, sources of channeling were made stackable. Wucad Mu refunds MP 1.5x as much (now counting as 3 sources, but each source was halved).
  • In 0.27, the staff was buffed: it refunds MP more often (1.5x) and refunds MP even when it backfires.
  • Prior to 0.26, the staff of Wucad Mu could be evoked to restore MP, but had a chance of backfiring when used in this manner.
  • Prior to 0.20, the staff's negative effects were based on Divinations miscast effects.
  • Prior to 0.12, the enchantments on this weapon depended on intelligence and were capable of reaching up to +22/+13.
