==Find the Keys and Plan== The first stage in unlocking the Infernal Machine players have to gather the keys. The four keywardens are located randomly somewhere in their levels, and may require some searching to locate. Remember that this entire event is [[Torment-only]] and the keywardens may not appear on lower difficulty levels, and will never drop a key below Torment difficulty.Key (and Demonic Organ) drop odds per difficulty level:* [[Torment I]]: 25%* [[Torment II]]: 28%* [[Torment III]]: 33%* [[Torment IV]]: 38%* [[Torment V]]: 43%* [[Torment VI]]: 50%Prior to [[D3v2]] key and organ drop odds were 5% even on [[Normal]] difficulty, and could be raised all the way to 100% on [[Monster Power 10]].<ref>[http://blues.incgamers.com/Posts/10/1/40/819/188318/mf--infernal-machine-keys#postId_504786 Drop rate at MP0] - Blizzard CM, 17/10/12</ref> <ref>[http://blues.incgamers.com/Posts/10/1/40/819/188833/act-3-key-warden-drop-rate-unbalanced Innate drop rates equal] - Blizzard CM, 22/10/12</ref> It was also necessary to have five stacks of [[Nephalem Valor]], though [[Magic Find]] did nothing to improve the drop odds.<ref>[http://blues.incgamers.com/Posts/10/1/40/819/188318/mf--infernal-machine-keys#postId_504786 Magic Find effects] - Blizzard CM, 17/10/12</ref> ==Keywardens==In D3v2 and RoS, all Keywardens have one key they usually drop, but they have a small random chance to drop additional keys of any type.[http://diablo.incgamers.com/blog/comments/keys-key-wardens] They might even drop two of the same key, from time to time.===Diablo 3===* The [[Key of Destruction]] may drop from [[Odeg the Keywarden]] in the Act I [[Fields of Misery]].* The [[Key of Hate]] may drop from [[Sokahr the Keywarden]] in Act II - [[Dahlgur Oasis]].* The [[Key of Terror]] may drop from [[Xah'Rith the Keywarden]] in Act III - [[Stonefort]].* The Infernal Machine Blacksmithing Plan (and random keys) will drop from [[Nekarat the Keywarden]] in Act IV - [[Silver Spire]] Level 1.===Reaper of Souls===*The [[Key of Bones]] may drop from [[Odeg the Keywarden]] in Act I - [[Fields of Misery]].*The [[Key of Gluttony]] may drop from [[Sokahr the Keywarden]] in Act II - [[Dahlgur Oasis]].*The [[Key of War]] may drop from [[Xah'Rith the Keywarden]] in Act III - [[Stonefort]].*The [[Key of Evil]] may drop from [[Nekarat the Keywarden]]in Act IV - Silver Spire Level 1<gallery>File:Odeg.jpg|Odeg in Act One.File:Sokahr the keywarden.jpg|Soharh in Act Two.File:Xahrith.jpg|Xah'Right in Act Three.File{{Template:Nekarat.jpg|Nekerat in Act Four.</gallery>The keys, plans, organs, and machines are all [[Bind to Account]] so must be collected by each player individually.}}
