How to Find Keys:
- Key of Terror - drops only by killing
the Countess (Act 1, Fogotten Tower)
- Key of Hate - drops only by
killing the Summoner (Act 2, Arcane Sanctuary)
- Key of Destruction - drops only by
killing Nihlithak (Act 5, Halls of Vaught)
Keys are not that hard to obtain. Magic find has no effect on how often keys drop
and neither does the number of players in the game. It is all luck. Keys drop about 1 in 34 runs and can only
be found on Hell difficulty. It is possible to get multiple keys in the same game and even multiple keys on the same
boss. Be patient, don't give up, and you should have the keys in no time.
