Grounded Armor Guide — Set Bonuses and Resistances

Three numbers, not one

Defense is the raw value used in the damage formula. Resistance is a flat percentage taken off all damage, no matter the type. Class adds a flat 0/20/30% (Light/Medium/Heavy) on top of Resistance. So a Heavy set with solid Resistance shrugs off more than a Light set with a bigger Defense number — and a resisted hit barely registers.

Full sets beat mixing

A full set triggers its set bonus. Mixing pieces keeps a small stat but drops the bonus, which is usually the bigger loss. Keep two or three full sets and swap per zone.

Match the set to the boss

  • Hedge Broodmother → Mother Demon or Ladybug (Heavy + poison).
  • Infected Broodmother → Roly Poly (taunt tank) or Koi (parry counter); bring heavy healing (Beefy/Sticky).
  • Director Schmector → Roly Poly Heavy; note poison, gas and bleed do nothing to him.
  • Orchid Mantis → Roly Poly plus a Salty weapon; perfect-parry every attack.
  • Assistant Manager → Black Ant (resists his shock) with a Busting weapon.
  • Wasp Queen → Widow or Wasp (poison / air); Waspidote to resist her poison.

Frequently asked questions

What does armor actually do?

Each piece has a Defense number and a Resistance percentage. Resistance cuts all incoming damage by a flat percent regardless of type, and the set's class (Light/Medium/Heavy) adds 0/20/30% on top.

Which set should I wear?

Wear the set that resists the bug you fight most. A resisted hit matters more than a high Defense number, because Resistance applies to every damage type.
