Armor Class m=Magic is the only way this creature can be harmed. Normal weapons simply bounce off or the wound instantly heals and e=elemental means that the attack must be from some elemental source such as earth, air, fire, or water as described in monster description and s=silver means silver weapons must be used to hit this creature.
A Plus + mean Armor can give greater AC
Hit Dice are how many d6 that you roll for the monster's hit points. All monster save at +1 for every 2 hit dice for attacking and any skill check unless there is another modifier listed. Saves against monster's spells or poisons is at 10 + ½ Hit Dice Some monsters may have an additional save against certain types of attacks.
Movement is how many feet the monster moves per round in combat or in a turn on a map.
