==Useful Info==
'''Orbs of entropy''' (or '''OOEs''') are some of the nastiest foes to be faced in the Dungeon, capable of blasting unwitting adventurers with high-powered bursts of [[negative energy]] and [[acid]] damage. They can also rapidly inflict [[doom]] and [[banes]].

They can be found within [[the Realm of Zot]], especially in the [[Hall of Zot]], where their presence is revealed by statues outside of the [[Temple]] and the entrance to Zot. They alternate with the [[orb of fire]] and [[orb of winter]] in each game. Regardless of which orb type you find in Zot, they can appear in negative-energy themed [[Ziggurat]] floors.

==Strategy==
Orbs of entropy can cause fights to spiral out of control, dealing heavy direct damage as well as inflicting long-term [[drain]]ing and banes which can complicate further encounters.
*Their [[Bolt of Draining]] can be fully resisted with rN+++, so strive to obtain maximum resistance.
**[[Undead]] species get free immunity to their bolt of draining. However, Doom from their [[Ill Omen]] will be much harder to remove, and any Banes gained will be difficult to clear up in Zot.
*On the other hand, [[Acidball]] can only be 66% resisted, but only requires one rCorr item. Having at least a [[ring of corrosion resistance]] as a swap is advised.
*Ill Omen requires a line of fire to affect the player with Doom, so any sort of summon can block it. However, many summons are weak to Acidball, and Ill Omen can even afflict undead and nonliving summons with debuffs if they are Doomed enough.
*Orbs of entropy, despite being made of the essence of negative energy, are nonliving and not vulnerable to [[holy]] damage. They are still considered [[evil]] and will give some piety when killed while worshipping [[The Shining One]].
*Orbs of entropy cannot open [[door]]s.

===Tips & Tricks===
*[[Silence]] is worthless against orbs of entropy.
*Compared to orbs of fire, orbs of entropy only have rF+ and rC+, but have acid immunity. Their high [[AC]] makes it difficult to damage them with low-power [[fire magic|fire]] and [[ice magic]] spells, but it is possible.
**Orbs of entropy are completely immune to electric, poison, and negative energy damage.
*Orbs of entropy can and will fire their damaging spells through one-another (Acidball requires you to be adjacent to the blocking monster). They can also fire Bolt of Draining through other negative energy-immune monsters like [[ancient lich]]es.

==History==
*Orbs of entropy were added in [[0.34]]
