Iron Soul Dungeon Armor List: All 80 Pieces by Base HP

Armour carries two things: base health, and the sub-stats that roll on it. Base health is listed below; the sub-stats are random per craft, which is why the official progression guide tells you to forge several light helmets on each new map and keep the one that rolls Attack Bonus or Skill Damage.

Forge costs differ sharply by slot: a light helmet is 3 ore at 100%, a light breastplate 10 ore at 80%, a heavy helmet 15 ore at 80% and a heavy breastplate 22 ore at 100%. Full table on the forge page.

Light or heavy armour?

Heavy pieces carry the larger health pools and are the recommended chest slot from Frozen Valley onward, where the guide asks for 1,200 max HP before you enter. Light helmets stay relevant much longer than their health suggests, because at 3 ore per craft they are the cheapest way to fish for a good sub-stat roll. Blessing armour gives diminishing returns compared with weapons — the exact multipliers are on the blessing page.
