Very small one today - I'm testing the concept of 'temporary events' in the live environment as it relates to weapons and gear. Until the next update, items from the Tattered set will have an additional tooltip note, give +25% HP each, and disassemble into 1 Corrupted Essence in addition to the rest of its disassembly pool. This is expected to last only a day or two until I can see if there's any effects on database changes while players hold what amounts to legacy gear. Also, the "Basic" weapons set now give +25% to a relevant stat except the bow which gives +100%. Remember: Only newly acquired gear is affected by these back end gear changes.
This update internally is labeled as 8.2.1.3, but does not offer any changes beyond those 14 items. Tattered items drop from 24 different units in the game, including wolves, werewolves, the Scarlet Cavern Moomba, and all variants of the Veil version of the Headless Horseman. Basic set weapons drop mostly from An'ura, but also from veil-Headless, other bosses, and random oddities.
