Is the bonus mana retained after upgrading to Archangel's Staff?
The item Tear of the Goddess has the UNIQUE Passive:
Each time your Champion uses an Ability their Maximum Mana will increase by 4 Mana, up to a maximum of twice in a six second period; bonuses cap at +1000 Mana.
When you upgrade it to Archangel's Staff, do you retain the bonuses gained? Or do you have to start over?
Solution 1:
Yes, all bonus mana is kept, provided you are upgrading the tear into a staff, and not selling it or something crazy like that.
