Got offered double Mystic Vulnerability, from upgrading my Bullet & Spirit Lifesteals to an Enhanced Leech. The double Mystic Vulnerabilities gave a combined 15 spirit resist, based on what my stats stated. Based of replay, the Haze does not get double the resistance reduction from the item.
Same happened to me, i think it might be because both spirit lifesteal and bullet lifesteal upgrade into leech and that confuses the game. It also only shows one item at the end screen
