D2R Hell Immunity Calculator
Select your build's damage types and instantly see every Hell farming area ranked by safety. Green = no immunities, Yellow = partial block, Red = fully blocked. Includes all Area Level 85 zones and 8 class presets.
How Hell Immunities Work
In Hell difficulty, monsters can have resistances over 100% — making them immune to that damage type. Immune monsters cannot be killed by that element without a Conviction Aura or Lower Resist curse to break through. This makes your farming area selection crucial.
Color Code Explained
Green — No monsters in this area are immune to any of your selected damage types. Farm freely.
Yellow — Some monsters are immune to one or more of your damage types, but not all. You can still kill most things here.
Red — Monsters in this area are immune to every damage type you selected. You won't be able to kill them.
Best Areas by Build
Blizzard Sorc: Ancient Tunnels (no cold immunes, alvl85), Mausoleum, Arachnid Lair.
Hammerdin: Nearly everywhere — Magic immunes are extremely rare. The Pit, Chaos Sanctuary, Worldstone Keep.
Lightning Javazon: Ancient Tunnels, The Pit (watch for lightning immunes in some areas).
Fire Sorc: More restrictive. Look for areas with few or no fire immunes — use the calculator above.
Sunder Charms
Sunder Grand Charms (added in Patch 2.5) break monster immunities for a specific damage type by setting that resistance to 95% — not removing it. Resistance stays very high, so you still need stacked -enemy resist (Conviction, Lower Resist, Cold Mastery, facets) to deal meaningful damage. There is a Sunder Charm for each of Fire, Cold, Lightning, Poison, Physical, and Magic.
Sunder Charm acquisition got significantly easier:
- Latent Sunder Charms now drop from any monster, Terrorized or not, scaled by Magic Find — no longer Herald-exclusive.
- The increased-chance Herald drop now starts at Heralds of Dread Tier 2 (was Tier 4).
- Herald drop rate is no longer heavily modified by player count.
- If the Herald Sunder roll fails, there is an increased chance to drop a charm or amulet instead.
See the Sunder Charms guide and full Patch 3.2 notes.
