Resistances and Difficulty Walls
Most players who stall in Nightmare, Hell or Torment are not under-leveled. They are under-resisted. Armor only stops physical hits, so elemental and chaos resistance are what carry you through the back half of the game.
Armor stops physical damage only
Armor and damage reduction apply to physical hits. They do nothing against fire, cold, lightning or chaos damage. That is why a tank with huge armor can still get deleted the moment a stage starts throwing elemental attacks. Build armor for the physical layer, then build resistance for everything else.
Every resistance caps at 75%
Each resistance type maxes out at 75%. Once a resistance hits the cap, extra points in it are wasted, so spend them elsewhere. Open the detailed stat panel to see where each resistance actually sits, drop any points above the cap, and move them into HP or a resistance that is still short.
When each resistance starts mattering
The damage types come online as the difficulty climbs. Fire resistance is the first wall, showing up around the early burning stages and becoming essential by Hell. Cold and lightning follow. Chaos is the nastiest: it tends to start at a negative value, so closing the gap to the cap can take a large amount of chaos resistance, and from roughly stage 3-7 onward you cannot skip it. If you run two melee heroes up front, each of them needs its own chaos resistance.
How to stack it
Resistance comes from skill-tree nodes, gear substats, and Cube decorations. Some heroes get resistance nodes for free in their tree, which frees up gear slots for raw HP instead. Priest is the clearest example: her tree hands her capped resistance, so her gear can lean almost entirely into HP. For everyone else, slot resistance gems through the Hero-dric Cube and prioritize the type the current stage is hitting you with.
HP before armor once you are capped
After resistances are capped, raw Max HP is usually a better survival stat than more armor, because armor only ever covers the physical slice of incoming damage. Flat HP from gear tends to beat percentage HP until you already have a large base to multiply. Pair capped resistances with a deep HP pool and most difficulty walls turn into a gear check you can actually pass.
