Diablo 1 - Complete Walkthrough - Warrior

Diablo, who is an incredibly powerful demon, is the Lord of Terror and one of the Three Prime Evils of Hell, who had been imprisoned within a Soulstone and buried in the caverns deep beneath the town of Tristram centuries ago by an ancient people known as the Horadrim. Although his imprisonment was meant to be eternal, Diablo worked tirelessly to corrupt his Soulstone, eventually overpowering his prison. Diablo received help from the thoroughly corrupt Archbishop Lazarus, who had been turned into his loyal servant. However, in order for Diablo to actually manifest himself in the mortal realm, he needed a mortal vessel to house his spirit.
Diablo first tried to possess King Leoric, the local ruler of Tristram, but due to his weakened state and the strong will of the King, Diablo failed to gain full control. Therefore, the demon abandoned the King, which in turn left the King crazed and senseless. Lazarus then kidnaps King Leoric's younger son, Prince Albrecht. He leads him deep into the Catacombs where he inserts the Demon's Soulstone in the Prince's forehead. This allowed Diablo to possess and warp the prince, thereby attaining material form. Diablo may have a body now, but he is far from his full power, so he bides his time and summons countless hordes of demons, infesting the entire underground complex, gradually turning the region into an outpost of Hell.
The maddened King Leoric accuses the townsfolk of Tristram with the kidnapping of Albrecht, and has several people executed. His loyal knights try to calm him, but as the crazed king has completely lost his sanity they are forced to kill him. His dying words are a terrible curse, damning the knights into unholy servitude. Meanwhile, Lazarus emerged from the catacombs and rallied the townsfolk, leading them deep into the catacombs in order to save the prince. This turns out to be a trap - instead Lazarus lures and leads them to the lair of The Butcher. Many of the townsfolk are slain by the demons. Afterwards Lazarus flees deeper into the underground Dungeon.
Demons appear in the countryside as the Lord of Terror regains his strength in the very heart of the labyrinth and prepares, biding the time when he would once again emerge to seek out his brothers - Baal and Mephisto - and free them as well. It seemed to be only a matter of time until the three Prime Evils gained dominion over the entire mortal realm.
This is where the protagonist comes into play. As he or she fights their way through the sixteen levels in the Dungeon to face Diablo, they encounter various monsters, quests, tomes, scrolls, weapons, and other miscellaneous items.
