'''Orbs''' are magical [[tool]]s that appear in ''[[NetHack]]''. The only type of orb in the base game is the [[crystal ball]], which appears as a "[[glass orb]]" when unidentified.
'''Orbs''' are magical items in the [[tool]] class, which all share the unidentified appearance '''glass orb'''.
 
  
[[NetHack 3.6.0]] only includes one orb, the [[crystal ball]], so any "glass orb" you encounter can safely be assumed to be a crystal ball.

Some ''NetHack'' variants add multiple types of orb, including new glass orbs.
  
However, some historic variants contain more than one type of orb.  In these variants, a randomly generated "glass orb" can be any one of these items, making activation of an unidentified orb risky—you could waste a chance to [[enchantment|enchant]] a good weapon or [[charge]] an item, or you could even suffer the effects of a magical explosion!

All orbs other than the crystal ball have a base price of 750 [[Zorkmid|ZM]], whereas the crystal ball is worth 60, so it may be possible to single out the crystal ball by [[price identification]].  The orbs also [[Weight|weigh]] half as much as a crystal ball (75 units, compared to 150), so in the absence of a [[shopkeeper]] you might possibly determine whether an orb is a crystal ball or not by how it affects your [[encumbrance]].  But once the crystal ball has been ruled out, the three non-crystal ball orbs can only be distinguished by [[identification]], or by testing them.

===Orb of enchantment===
 
When applied, the '''orb of enchantment''' attempts to alter the enchantment of your primary wielded weapon.  This will only affect items in the [[weapon]] class, [[pick axe]]s and [[unicorn horn]]s.
 
 
 
*If blessed, the orb will always attempt to increase the enchantment, with a 50% chance of increasing it by 1 and a 50% chance of increasing it by 2 (''"Your <weapon> glows silver"'').
 
*If uncursed, the orb has a 2-in-3 chance of increasing the enchantment by 1 (''"Your <weapon> glows bright for a moment"''), and a 1-in-3 chance of decreasing it by 1 (''"Your <weapon> glows dark for a moment"'').
 
*If cursed, the orb will always attempt to decrease the enchantment, with a 50% chance of decreasing it by 1 and a 50% chance of decreasing it by 2 (''"Your <weapon> glows black"''). 
 
 
 
The maximum for enchantment is +5.  The orb will never increase the enchantment of a +5 weapon (''"Nothing seems to happen."''), and if the resulting enchantment would have been greater than +5 (e.g. if a weapon that was +4 would have gained 2 points of enchantment), it will cut off at +5.  There does not appear to be a cutoff to lowering the enchantment.
 
 
 
Applying an orb of enchantment that is out of charges returns the message "This orb is burnt out."

===Orb of charging===
 
When applied, an '''orb of charging''' allows you to select an item, which it recharges, like a [[scroll of charging]]. Its [[BUC]] status seems to affect its behavior in the same way as a scroll of charging.
 
 
 
The orb self-identifies when successfully activated.  Applying an orb of charging that is out of charges returns the message "This orb is burnt out."

===Orb of destruction===
 
When applied, the '''orb of destruction''' simply explodes, destroying the orb and dealing [[D-notation|12d6]] points of [[magic missile]]-type damage.  Whether the orb is charged or not does not seem to have any impact on this effect.

Also, all orbs in NetHack brass, including the crystal ball, weigh 75 units.  The crystal ball can still be distinguished from the other three by [[price identification]].

Orbs are magical tools that appear in NetHack. The only type of orb in the base game is the crystal ball, which appears as a "glass orb" when unidentified.

Variants

Some NetHack variants add multiple types of orb, including new glass orbs.

SLASH'EM

Two variants whose code became the base for SLASH'EM, NetHack Plus and SLASH 6, feature three glass orbs in addition to the crystal ball - the orb of enchantment, the orb of charging, and the orb of destruction. The orbs are a deferred feature: their code can still be found in the SLASH'EM source, but has been commented out with the note that these had "potential for abuse".[1][2]

NetHack brass

NetHack brass includes the orb of charging and the orb of destruction, but instead of the orb of enchantment there is an orb of maintenance that can be used to repair erosion on a selected object.

All glass orbs in NetHack brass weigh 75 units - the crystal ball can still be distinguished from the other three by price identification.

EvilHack

EvilHack introduces the eight-ball, an orb that is made of plastic. It serves as the base item for the Magic 8-Ball, an artifact tool always carried by the Oracle.
