All monsters have a predetermined maximum amount of life points. They will slowly regenerate life over time, and most monsters will heal to full immediately if they are out of combat for too long. For players, the maximum amount of life points is determined by their Constitution level. Every level gives 10 life points to the base amount, starting at 100 for level 10, and capping at 990 with skill mastery. Life points are also given by higher level armours, granting a permanent increase to maximum for as long as they are worn. Certain foods and potions (such as rocktail) can heal beyond maximum life points, but these extra points will slowly drain over time similar to the natural healing mechanic. A small boost to life points can be gained by stoking a bonfire with 5 logs.
