Act 4

Act IV: The Harrowing

The Fallen Angel

Objective: Kill Izual, found in the Plains of Despair

Quest Reward: Talk to Tyrael for reward of 2 skill points.

Multiplayer Notes: If a partied player killing Izual has previously completed the quest, a questing character must be within roughly 1-screen distance from Diablo to receive credit for the quest.

The Hellforge

Objective: Smash Mephisto's Soulstone with the Hellforge Hammer, which is dropped by Hephasto the Armorer

Quest Reward: Smashing the Soulstone produces one perfect, two flawless, and one normal-quality gems, in addition to one rune. The rune that drops has an equal chance of being one of eleven different runes, depending on the difficulty level of the game. The runes that can drop from the Hellforge in each difficulty level are:

Normal: El-Amn

Nightmare: Sol-Um

Hell: Hel-Gul

Multiplayer Notes: This quest will be completed for all partied players in Act IV when the Soulstone is smashed. For each additional party member, the Hellforge quest will drop one additional perfect gem.

Because the marginal reward for each additional party member is so low compared to completing the quest alone, the Hellforge quest is typically completed outside of a party. It is considered good etiquette to leave the party before completing this quest.

Terror's End

Objective: Kill Diablo

Quest Reward: Quest drop if killed by questing character.

Multiplayer Notes: If a partied player killing Diablo has previously completed the quest, a questing character must be within roughly 1-screen distance from Diablo to receive credit for the quest.

When being power-acted, low-level characters often hide behind two outcroppings in the wall directly above where Diablo spawns. If Diablo remains where he spawned, the low-level characters will be shielded from Diablo's attacks, while still being close enough to receive quest credit.
