Tu portes bien ton nom, surtout la dernière syllabe. Avant de pourrir ce site de chose inutile, créé toi une page web. De plus sur un site anglais tu aurais eu l'intelligence de tout mettre en anglais.
There's three ways to get healing -- the Sorcerer starts with a spell that can drain health from an enemy in front of him and give it to any hero. The Paladin can buy a healing ability if he saves up 2 ability points. And if you can make it to an Inn, you can have a nice rejuvenating rest, for a price. :)
Do you have any sergeants? If so, it takes a period of time (100 seconds, to be exact) for 1 sergeant to train 1 soldier.
