Diablo 4 Corrupted Reaper Boss Guide (Season 14) – Location, Mechanics & Loot Table

Diablo 4 Corrupted Reaper Overview

The Corrupted Reaper is a Season 14 Lair Boss introduced in Season of Death Awakening, positioned as a pinnacle endgame encounter designed for Mythic Unique farming and high-tier loot progression.

Unlike traditional world bosses, the Corrupted Reaper is integrated into the Lair Boss System, meaning:

• You fight it repeatedly from a dedicated altar
• Loot is claimed via a post-fight Hoard chest
• Reward access requires seasonal key materials
• Drop quality scales heavily with Torment difficulty

2. Reach Torment I+ difficulty
3. Unlock the Summoning Altar

Phase 1 – Scythe Control Phase (100%–66%)

• Wide scythe arc attacks

• Teleport dash attacks leave damage trails
• Shadow decay pools appear on ground
• Attack speed + movement slow debuff zones

👉 Strategy:

• Rotate around arena edges

📌 Confirmed escalation of dash frequency and hazard density in Phase 2.

Phase 3 – Execution Phase (Below 33%)

This is the deadliest phase.
