Wearing a matching outfit can feel good, but in MMORPGs that usually means collecting a gear set to earn latent bonuses for doing so. That experience can now be had in Embers Adrift thanks to the latest update, which introduces set bonuses for equipment.
These new bonuses exist for outer armor, inner armor, and jewelry pieces, and are a part of preparations for upcoming content. Unfortunately, items from existing quest rewards will not feature any set bonus benefits, but future quest rewards may do so. The new patch otherwise applies a long list of fixes for environment, monsters, XP earnings, and quest step bugs.
