The world of Arena can be a deadly place. The following section will aid you in aiding yourself. There are basically 5 things that can affect you in the world: 1) damage to you during combat, 2) diseases, 3) having a curse inflicted upon you, 4) poisoning, and 5) paralyzation. Each of these cases will be taken in turn below:
To heal up wounds you have sustained after a big fight, you have a few options. You can:
If you are unlucky enough to contract one of the many diseases possible in the world, you must get yourself cured quickly. Diseases, unlike other damaging effects, slowly degrade whatever they normally attack. In the case of a disease such as Wound Rot, your Strength, Endurance, and Health slowly reduce until one of them reaches zero. At that point you will die. There are a few options available to you:
A curse is similar to a disease except that it affects your INT, WIL, PER, and LUC. As with all other degenerative attacks, if any of your stats reach zero, you will die. The good thing about curses is that they seldom have a duration long enough to threaten your life. Still, having your INT down to 15 isn't helpful, nor is it safe. If you are hit with another curse it could kill you. Follow the steps you would if inflicted with a disease and you should be able to ward off a curse or banish it at a temple.
Poison causes a slow degeneration of your Health. Obviously if your health reaches zero, you will die. Once again the steps to preventing it are relatively simple. Prepare beforehand. Buy the necessary potions and/or spells to safeguard yourself. If you find yourself in the unlucky circumstance of not having any of these things, try resting. Certain poisons will wear off given time. Others will continue until you are dead. Don't take a chance. Keep your health as high as possible until you can rid yourself of the poison, whether that be through a spell or potion or at a temple.
Paralyzation is unique in that whatever paralyzed you is probably still around. The only good defense is to have a spell or a potion that you can use to cure of it. (Don't worry, paralyzed characters can move enough to take a potion, just not fight or run.) You can also cast some other type of spell such as Invisibility or Sanctuary, which would cause the monster or person to ignore you. Hopefully the spell will last long enough for the paralyzation to wear off. If you don't have any of these options you are in some trouble. The monster will continue to attack you. Although further attacks won't add to the paralyzation time, rarely does it have to. Your only hope is that the effect wears off quickly. As stated before, the best defense is to prepare beforehand.
