Poison Effect

Some attacks used by monsters have a poison effect against other monsters. If the attack hits, the monster will take normal damage as well as become poisoned, and then take one point of extra damage immediately. Every turn the monster is attacked, whether it's a hit or miss, the monster takes one point extra damage due to the poisoning.

Poison does not stack, a poisoned monster takes 1 point damage when attacked, if an attack with poison succeeds in hitting them again, it will act as a normal attack.

Poisoned monsters will not take poison damage if they are not attacked with the attack command. Using an item, even an attack item, on a poisoned monster means they will not take poison damage. Poisoned monsters will also not take poison damage while benched.

Using items Potion (+20) and Potion (+10) on a poisoned monster will cure them of the poison, however, they can be poisoned again.

Healing the monster with the healing barcode also cures poison.

Tips
If a monster has a poison effect, it is a good idea to attack with the poison attack for the first round and then use the strongest attack from then on to get maximum damage.
