Top Map Mods to Avoid for Boss Fights
1. Elemental or Physical Damage Reflect
Mod Examples:

“Monsters reflect X% of Physical Damage.”

“Monsters reflect X% of Elemental Damage.”

These are build killers for elemental casters and physical attackers. Reflect mods will bounce your damage back at you, potentially killing you instantly. Even builds with leech or regeneration may not out-heal the incoming self-damage, especially in high-tier maps or versus tanky bosses.

Counterplay: Only run reflect maps with builds that do not deal the reflected damage type, or use reflect-immune skills (e.g., via specific pantheon powers or support gems in PoE1; we’ll need to confirm what PoE2 offers post-release).

2. No Regeneration
Mod Example:

“Players cannot regenerate Life, Mana, or Energy Shield.”

This mod is brutal during prolonged boss fights. Without regeneration, sustain becomes a major issue—especially for mana-based casters, aura stackers, and hybrid builds relying on energy shield. Builds that depend on constant regeneration for survivability, such as Righteous Fire or Essence Drain, will struggle.

Counterplay: Prepare with instant recovery flasks, mana leech mechanics, or avoid the map entirely unless you’re certain your build can function without regen.
