It is build from:
Tear of the Goddess
Heart of Gold
30 armor
250 health point
1350 mana
7 mana per 5 seconds
Passive: Whenever your champion attacks, they gain 1 max mana (2 second cooldown). Whenever your champion uses an ability, they gain 4 max mana (3 second cooldown).
Bonus mana caps at 1000.
Unique passive: 1.5% of your maximum mana is converted to armor.
Price:
Around 3100?
I think this item would work well on many champions, such as Maokai, Malphite, Ryze, Urgot etc.
However, I think it might be OP on champions, who also scales well with Archangel Staff or Manamune?
