Unlimited mana

[kmnWolfman]

I'm not sure if this strategy is known, but I use it to get unlimited mana.

The Bear, Ancient Bear and Polar Bear all have the Hibernation talent. Using it, by hitting the Defend button, the bear falls asleep and does not retaliate the enemy's attack. So I usually use Blind to save one enemy troop for the end of the battle, while I kill all the rest. Then I make sure I keep all my units away from the saved enemy group while only the bears stay close to regenerate mana with Mana Spring.

So the end of most of my battles goes like this:

1. I cast the Magic Spring spell on the bears.
2. The bear defends and falls asleep.
3. All my other units defend swell.
4. The enemy troop is too far to attack any other unit so it attacks the bear. The bear DOES NOT retaliate, it just regenerates mana.
5. I keep defending until Magic Spring runs out.
6. GOTO 1.

It takes a while but you get a sure source of unlimited mana.

I tried searching the forum for other ways to get unlimited mana but I didn't find anything else. Are there any other such threads?
