Lord of Hatred Encounter Guide

Mephisto features multi-element attacks (poison, lightning, shadow); Unstoppable is mandatory.

  1. P1

    Phase 1: The False Prophet

    Stay close to the boss while dodging telegraphed ground detonations.

    • Dark Arrival: Let center detonate first, then step inside.
    • Hatred's Gaze: Narrow beams; sidestep gently.
  2. P2

    Phase 2: Lord of Hatred

    Mephisto reveals his true form at 66% HP, coating arena with shadow spikes and poison tides.

    • Pestilent Tide: Radial poison burst; evade when green ground spawns.
    • Tempest of Ruin: Circular lightning orbs; weave through predictable gaps.

Site update log

  • S15 affix demand refreshed: 4,053 samples with per-class affix priorities recalculated; tuning prism pools and the loot filter dictionary were re-signed in the same batch.
  • S15 wrap-up data refresh: 15 new builds and 20 new Tower runs. The 20 runes removed this season stay in the codex and search, marked "Unavailable this season", and the dual-rune meta now counts only combinations that are still socketable this season.
  • New Tuning Prism affix pool page: see exactly which affixes each of the six Horadric Cube tuning prisms can roll — search affixes, filter by prism, or reverse-look-up which prism rolls a given affix. Tempering rows in the affix table now label their prisms too.
