Skovos, at the end of the Lord of Hatred campaign. Season of Hell's Legacy also features him in the seasonal Prime Evil quest.
Mephisto
Mephisto is the Lord of Hatred. He is the final campaign boss on Skovos, and Season 15 sends you back to the Prime Evils, including him.
Loot
Campaign completion unlocks Skip Campaign for the rest of the account. Seasonal splinters and Prime Evil Powers come from the Season 15 quest, not from a lair-key hoard.
Tips
- Finish the Lord of Hatred campaign on one character so later Seasonal characters can skip it.
- In Season 15, complete the seasonal quest before you use a Soul Splinter. Patch 3.2.3 fixed a bug where an early Splinter locked that character out of Prime Evil Powers.
- He is a story fight with a large health bar. Bring the Torment build you use for other bosses, not a leveling bar.
