Nightmare is an A-Grade armor in three kinds: Heavy, Light and Robe. Each kind has its own set effect while you wear the whole set. Dwarves craft the pieces (see Recipes: A-Grade Armor); a craft gives the sealed piece and a town Blacksmith breaks the seal. Each piece also has a Masterwork version: see Nightmare Armor: Masterwork.

Enchant bonus
When every piece of the set is enchanted to +6 or more, the set gets an extra bonus, and it grows again at +12, +16 and +25. The lowest enchant among the pieces counts (the shield does not). Each row is the whole bonus at that enchant. In the Olympiad, a piece counts at most at the Olympiad enchant limit.
