Item sets (Origins)

Throughout Dragon Age: Origins characters can collect armor sets that provide them with extra benefits when equipped together. The various pieces of each set can come from various tiers and still return set benefits. So, for example, a tier 4 (Hardened) Leather Armor will reduce skill costs when matched with a tier 2 (Cured) Leather Boots and a tier 1 (Rough) Leather Gloves. However, a tier 4 (Hardened) Studded Leather Boots would not enable that benefit. Also, helmets are not required to complete most sets, nor do they usually benefit from being equipped with "matching" gear.
