Moon Well (Warcraft III)

eplenish Mana and Life (Autocast)

 * Replenish the life and mana of a target friendly unit.

For every point of mana it has, The Moon Well will replenish either 2 Hit points or 0.5 Mana. If a unit that has mana uses the Moon Well, it will partition half of its mana for Life, and the other half for Mana replenishment. For example, if the Well has 100 mana, it can replenish 100 health, and 25 mana when used.

If a unit with 200/600 Hit points and 90/100 Mana uses a Well with 100 mana, 50 of the Well's mana will be used to replenish 100 hit points. The Well only needs 20 mana to fully recharge the unit's mana, and so the remaining 30 is routed back to replenish an additional 60 of the unit's life, for a total of 160.
