The Dungeon spider is a monster which is found in Daemonheim that looks exactly like a regular Giant Spider on the surface. It was released along with the Dungeoneering skill. These monsters hit low for their level, but are very accurate to compensate, and can consistently hit even through high level magic armour.
Members should be further warned that it poisons occasionally so a cure potion or antipoison would do the favor for you. It is suggested that gamers using the latter should ulitize it after the spider is dead as the antipoison bought from the Smuggler in Daemonheim does not give temporary immunity.
It is weak against magic attacks, particularly air spells. Protection prayers do not prevent it from inflicting poison (as with other poisonous monsters). These spiders are firstly discovered in the Abandoned floors.
