Staff

General
A staff is a two handed, ranged weapon for the "spellcasting professions"
 * Monk
 * Mesmer
 * Elementalist
 * Necromancer

''Note: Staves are the two-handed alternative to the combination of a right-hand Wand and a left-hand Focus. The discussion whether a staff or a wand/focus combo is superior is as old as the game. See section "Upgrades and Modifiers" for a few aspects of the discussion.''

Damage Stats
The maximum damage range of all staves is 11-22, the same as a Wand.

Depending on the linked profession and attribute staves deal various damage types. See "Staff Types" for details.

Staves - just like Wands - have a range of 80 ft, that means slightly less than the aggro circle.

Staves - just like Wands - have a rate of fire of 1.75 seconds.

Upgrades and Modifiers
Staves - unlike Wands - always come with an energy bonus included. The max possible energy bonus of all staves is +10, slightly less than a Focus which has +12.

Staves - unlike Wands - can be be equipped with a magic head (name prefix) and/or wrapping (name suffix) to add extra bonuses to the weapon.

Furthermore a staff - just like a wand or focus - may come with a number of non-salvagable magical modifiers.

See "Weapon upgrades" for details.
