4 complete armor sets — 17 of 20 armor pieces belong to a set. Collecting all pieces provides implicit synergy through matching defense types and Abyss Gear slot coverage.
Endgame cloth/leather set. Highest DEF values in the game. Drops from the Dark Ringleader boss in Demeniss (Lv 25-40). The best armor for caster and hybrid builds.
Mid-game plate/leather hybrid set. Found in Hernand (Lv 1-20) locations. Excellent for the transition from early to mid-game. The only set with a cloak piece.
Early-to-mid game full plate set. Found in Hernand locations. The first complete 5-piece set most players acquire. Covers all 5 equipment slots.
Starter plate set. Craftable from common materials. The first upgrade from starting gear. No cloak — pairs well with Scout Leather Vest for the chest slot if you need lighter weight.
