You can place your assembled equipment set into the Exhibition Hall to gain powerful set buffs. Once you place a set in the Exhibit Hall, your hero will not be able to use the equipment in that set until you remove it. Note: Removing any piece of equipment will deactivate the set buffs. After placing a full equipment set into the Exhibition Hall, you'll only enjoy the set buffs and won't benefit from individual equipment buffs. Equipment comes in six qualities, resulting in six levels of set buffs. The level of the set buffs is determined by the level of the Exhibition Hall and the lowest-level equipment in the set. As you upgrade the Exhibition Hall, you can enjoy higher-level set buffs and your set buffs level is determined by the lowest-level equipment in that set.
