Diablo III - Act I - The Legacy of Cain

Diablo III - A Completionist Guide

Act I - The Legacy of Cain

These guides are not intended to teach you how to play the game, but are instead full documentation of where all of the completionist goodies can be found. This includes finding all of the dungeons, events, conversations, and lore books. We assume this is not your first playthrough, and don't recommend trying to get everything the first time around as you'll need multiple map resets to get everything - and you must have played through Act II to get all of the blacksmith and jewelcrafter's conversations anyway. Enjoy!

Act I - The Legacy of Cain  is the second quest of Act I. This guide will walk you through the quest in order to find each dungeon, conversation, lore, and other goodies. Completion will certainly take multiple map restarts.

• Situational Awareness - Kill 1,000 enemies using the environment

After exploring, head down to Leoric's Passage. Save Cain. There is an achievement for killing "Headcleaver" (the rare) before killing any of the other skeletons.
