Most in-game activities give you experience. When you have enough experience your level increases. Every level up gives you +50 maximum health, +1 maximum energy, 3 skills points which you can spend to learn new skills. You also fully regenerate health and energy every time you level up (up to level 49).
Please note that starting from level 50 your health and energy won't automatically regenerate on level up. Instead you will receive 2 potions with the same effect - Ultimate Potion of Healing and Ultimate Potion of Refresh. You can use these potions whenever you like.
Your health and energy are fully restored if you are not in the game for 6 or more hours.
There is an option to refill your health automatically. Click the grey potion icon under your health bar and then choose a potion. When you run out of health to survive the next attack, the game will automatically use a number of chosen potions to refill your health. Energy autorefilling works the same. Click the grey lightning icon and choose a potion to be used to refill your energy automatically.
Some equippable items can increase maximum energy and maximum health. Please note that if your maximum health/energy changes due to equipment or skill change the following happens:
When the maximum amount decreases:
- If the current amount is less than the old maximum, it stays the same (can't be greater than the new maximum).
- If the current amount is equal to the old maximum, it becomes equal to the new maximum.
- If the current amount is greater than the old maximum, it decreases by the same amount as the maximum.
When the maximum amount increases:
- The current amount stays the same. If the current amount is less than the new maximum, it starts or continues regenerating.
