Other important tips
Burning and poison effect damages enemies by an amount proportional to their health.
Some monsters, such as werewolf, can regenerate vitality with great amount and fast pace. A green number rising above them indicates the recovered health. If further attack is found in vain, the player should not take this quest on the current level even if it is close to the suggested one. Simply level up and make the slash more deadly.
