Item Name: Mana Potion
Purchased From: Base
Used In: None
Brief Summary: A Mana Potion can be used on an ally unit to restore Mana over time. These are more powerful early game in the laning phase and on certain jungling heroes. Be sure not to take damage while using a Mana Potion, or it will be debuffed, and the remaining duration will be wasted. These restore 3.33 Mana per second, or 100 in total over the 30 second duration.
Recommended For: Certain heroes that use a lot of Mana early game, such as Vindicator or Myrmidon
Pros: Gives you the Mana to cast more spells early in the game
Cons: Opportunity cost; you're passing up other items (minor totems, etc) if you get these (which is true for any item, but is more dire early game)
