There are a helluva lot of monsters to be found, and beaten, in LAD.
Monsters can be tackled using physical and distant combat. In physical combat, you bump into a monster. You may do that with bare hands, but then you won't live long. You'd better wear appropriate weapons and armory. Wearing such an item will improve your weapon class or armor class. Each type of weapon will give you a certain amount of extra AC or WC points. Apart from that, they may have extra power or curse, indicated by numbers behind them.
DO NOT EQUIP ARMOR OR WEAPONS WITH A NEGATIVE VALUE. These items are cursed, and will decrease your WC or AC. You cannot take them off, unless they break, or by magic.

You can als battle monsters using magic spells. These can be read off a scroll, or cast. You can only cast a spell if you know it. You learn spells from reading books. Casting spells cost spell points. For more information on spells, check the Magic Page.
Monsters can also curse you. Some have special talents, but all can critical you, which means you'll have 2 pips left. So beware.

There are loads of different kinds of monsters. Here's a list of them, their AC and WC, their experience value, and optional information.
