Rage: By sacrificing Intelligence and Resistance, you can gain the same values in Strength and Endurance. You can sacrifice up to ten points per level.
Berserker: upon suffering damage, you gain an extra of ten points of strength and speed by each ten percent of your health lost. The points will increase by ten with each level up.
