Staff of power
|This staff provides a reservoir of magical power to its wielder.|
A staff of power is a magical staff which contains additional MP for you to expend when casting spells. It can hold 5 + (40% of your max MP) MP , and will regenerate MP independent of your actual MP pool so long as you wield it. Unwielding it, however, will cause it to rapidly bleed out MP, rendering it useless soon after you switch weapons. So long as it's wielded, however, it is effectively a large boost to your MP pool and MP regeneration rates.
The staff can also be used in combat, functioning as a +0, +0 staff. Unlike some other magical staves, it provides no magical combat effects, but you can still improve your damage output, accuracy, and attack speed through training Fighting and Staves.
The proportional MP bonus of this staff considers only your innate max MP, ignoring such sources as rings of power, mutations, and divine vigour. Note that the final max MP given by all non-innate sources, including this staff, is subject to a stepdown. Specifically, any max MP over 50 is halved. For example, this means a character with 45 innate max MP who wields this staff will have 59 max MP, instead of 68.
One of the more universally useful magical staves, a staff of power can benefit any caster. That being said, it may be wiser to wield a staff of wizardry if your spell success rate isn't terribly high; being able to cast a spell once reliably is better than being able to fail to cast a spell multiple times.
In 0.17, this staff will grant a flat +15 MP, and will lose the separate reservoir mechanic.
Prior to 0.16, the additional MP was treated as a bonus to max MP, not a reservoir contained in the staff.
Prior to 0.13, this staff granted a flat +13 MP, although subject to the same stepdown for max MP over 50.
