A Giant poisonous spider is a crafted monster, meaning that players can only encounter it after releasing it from its respective box, doing so gives the player 1.2 Monstercrafting xp. Creating and releasing the box requires a Monstercrafting level of 26. The creature can poison players for 80 damage. It has a very high chance of poisoning the player, so lower leveled players should bring antipoisons to the battle.
