The relationship between the power of a sorcerer and its level

Since a sorcerer’s skill tree has offensive spells layers. At the level 10, its skill tree will open unique divine powers for Elyos and Asmodians, as well as a sleep spell and a passive flight skill. Once reaching level thirteen, its defensive skills are even enhanced. At the level 13, they are allowed to open the dimension door and robe of earth skills. The robe of earth skills can improve MP regeneration, fire and water resist for a good period of time. When they reach level 16, they will be granted with the option to increase their maximum mana and as their level raises, higher and better spells becomes available at their disposal. When their level gets higher, they will be able to bring exceptional crowd and AoE(area of effect) under control. When they reach much higher level, their potential power on powerful spells and useful spells will be revealed by thir stigma skills.
