Friendly Mana is a special replenishable resource which you can use to restore your health or energy when you need to. Friendly Mana can be only received from your allies in the game.
How to use Mana
You can use mana to restore your health or energy, one point of mana restores either 2 point of energy or 100 points of health. You can use mana either from the refill dialog appearing when you're out of health/energy or from your 'Alliance' page.
You can use as many mana points as you have, but the game won't take more points than it is necessary to replenish your current health/energy to its maximum value. For example, if you have 10 points of energy missing the game will only take enough mana to replenish 10 energy and will keep the rest of mana untouched.
How to restore Mana
When you're out of mana, you can restore it by asking your friends to give you some. It won't cost your friends anything, they just have to agree to help you when checking their Inbox. Each friend can give you 5 mana points per day.
To ask your friends for mana please click the 'Ask Friends' button in the refill dialog or visit your 'Alliance' page and click the 'Ask Friends' button in the 'Friendly Mana' block. You'll be able to send social network requests to your friends in the appeared dialog.
How can I increase my maximum mana?
You can increase your maximum mana by inviting your friends to play Witchcraft. As soon as your friend reaches level 10, you will receive a reward which includes increasing your maximum mana. Your friend will receive the same reward.
You can also increase your maximum mana by learning the “Friendly Support” skill.
