Leveling (Hero)

Players are represented in game by a male hero character which gains experience with each mission fight and levels up as he reaches certain experience levels. Each new level increases hero's HP amount which is very helpful during the fights. Both regular (mana-paid) as well as raid campaign fights are counted towards earning the experience, while PVP, dungeon and event fights are not. After the first 30 or so easy to gain levels it gets increasingly more difficult to gain the new levels - with each new level requiring approximately 20% more fights to earn.

 * Note: "Days to next level" is the minimum number of days required assuming the player gets 288 mana points a day and uses them all to fight the first campaign mission, which costs 10 mana points. Normally players would chose more expensive missions which increases the total number of days required to level up.
