The patch is also bringing a number of item changes. For example, two-handed weapons will now count as two items for item set bonuses, hopefully making sets easier to build and maintain even with a two-handed sword. Several abilities have also gained new added effects, such as a healing effect added to Ash Cloud and a Block Effectiveness buff added to Bound Armor. Light and Heavy attacks have also been more effectively tied to their roles of dealing damage and refilling resources, respectively. It should make the game’s combat more fun when the patch arrives.
