Tear of the Goddess and Manamune unique passive Mana Charge grants mana on spell cast and mana expediture AND passively grants 1 mana every 8 seconds. Yet the second effect is missing on Archangel's Staff. Why when they both build out of tear?
I believe that it is because Archangel's Staff is a lot easier to stack as it grants 8 mana per spell cast. They only recently added the 1 mana per X seconds to Manamune because Manamune was harder to stack even than Tear of the Goddess, making it feel punishing when you upgrade it to Manamune.
