I was playing a game as Blitz today and noticed something with these 2 items. I had Manamune most of the game. Then for fun I sold my Philo Stone for an Archangels Staff. When the tears passive went to 750 I got the Seraph's Embrace and the Manamune reset back to 0 but I still had the 750 from Seraph's Embrace. And then the Manamune's unique passive started to count up again.
I'm sure this was not intentional and most champs wont need both, but some could use this to their advantage. I thought I would bring it up to Riots attention so they could fix the glitch/bug unless it was intentional considering the upgraded items don't seem to have the Unique passive.
So could someone just get 2 Archangels and allow this to happen for them? To stack up even more Mana?
