[[File:Headcleaver2.jpg|left|thumb|250px|Headcleaver]]It's worth exploring all this level even if you come across the entrance to [[Leoric's Passage]] early because it's this level that the [[Black Mushroom]]s can be located in. They are a reagent for the [[Staff of Herding]] which grants you access to [[Whimsyshire]].
Move on to [[A Shattered Crown]] quest.

==Objectives in Brief==
===Hunt for Cain===
* '''Objective:''' Hunt for signs of Deckard Cain
[[Image:LegacyCainCathedralFront.jpg|left|thumb|250px|The old Cathedral.]]
Leaving Adria's hut and heading north a bit, the player will find the entrance to the [[Cathedral]], which is a fairly faithful recreation of that from Diablo I. If the Cathedral in Diablo I had been hit by [[The_Meteor|a meteor]], that is.
Some zombies will spawn near the front entrance, where the [[butcher]] quest giver used to be in Diablo of old.
Dispatching the zombies, the player moves into the cathedral, and enters through the gaping blue chasm left behind by the fallen star. The player character literally jumps down and lands on the first level of the cathedral.
This is the first actual dungeon of the game, and thus also the first chance the player will have to encounter a [[Treasure Goblin]] and snag its [[lore]] entry, along with a few other monsters along the way.

The objective of the quest is to look for signs of [[Deckard Cain]], but as the first level of the Cathedral does not house prune juice or adult diapers, the player will descend down into [[Leoric's Passage]].
===The Legacy of Pain===
* '''Objective:''' Save Deckard Cain
After taking a few steps into Leoric's Passage, the player will be greeted by something new to the Diablo franchise--a cutscene. This is not to be confused with a pre-rendered [[cinematic]] that Blizzard is renowned for, but an in-game cutscene used to deliver narrative.

In this cutscene, Cain will be spotted running from skeletal assailants past a ridge carved out by the fallen star, which collapses after he passes, dropping some skeletons into the chasm below. Cain looks back to see the ghost of [[Leoric]] materialize, who then speaks:
::''The power of the fallen star awakened me, and soon, all will suffer as I have suffered. Guards, bring me his bones! ''
Leoric will then summon skeleton guards to attack Cain, who surprisingly attacks back with his walking stick, perhaps channeling his inner-[[Archivist]]. The player is then able to go down the stairs and assist Cain by dispatching a few waves of skeletons.

Eventually, a superunique named [[Headcleaver]] will spawn with a small posse of armed skeletal guards and attack the player. Headcleaver does not appear to have any unique abilities or pose any sort of real danger. Once dispatched, Cain will address the player, asking why the hero saved him, which in reply is told that Leah is looking for him.
Cain then leads the player to a secret passage which leads to the [[Cathedral Gardens]] with a convenient waypoint nearby as well.
Returning to town, the hero witnesses a sentimental reunion between Cain and Leah, before Cain gives the player the information they sought when coming to Tristram in the first place: knowledge of the fallen star, and what Cain can tell the player about it. Which ends up being, according to Cain...
::''Not much, I'm afraid, though the Prophecy of the End Days surely points to it as a sign that the end has begun...''
Which then signifies the end of the quest, rewarding the player with a pittance of [[gold]] and [[experience]], and the warm fuzzy feeling from knowing that they helped an old, helpless friend, wandering sadly and listlessly in an old possessed cathedral.
The player must speak with Cain again to begin the quest [[A Shattered Crown]].
==Quest-Specific Bugs and Issues==
* After the cutscene with Cain in the cathedral, if a [[Barbarian]] performs a [[Leap Attack]] from the top of the stairs, without walking down the stairs, the [[Headcleaver]] event will not trigger. The workaround for this is to return back to the foot of the stairs to trigger the skeletal spawn.
* [[Skeleton]] bestiary entries do not have audio attached. They can only be read in the bestiary.
==Trivia and Easter Eggs==
The quest name "The Legacy of Cain" may have been in homage to a game named "Legacy of Kain" developed by Silicon Knights/Crystal Dynamics.
==Strategy and Tips==
While in normal difficulty it isn't likely a player would need tips or tricks for strategy with ''The Legacy of Cain'', it's worth noting a point or two for higher difficulties.
As displayed in the video below, with some good timing and proper positioning, the player can use a dying [[Grotesque]] as a very potent [[area of effect]] attack. Once the grotesque "pops", it will deal damage to anything in its vicinity, including monsters.
The damage it deals can quite often kill a screen full of monsters in one hit, without requiring resource-heavy AoEs from the player.
