|Is it a spider or is it a shadow?|
The Shadow spider is a level 52 monster. If a player attacks this monster or the monster attacks them, it will drain their Prayer points by half of the current amount, rounded up. They can never take away a player's last prayer point. All Shadow spiders except those found in the Wilderness are unaggressive to players with a combat level of 105 or higher. Several of these monsters are found near the entrance of the Waterfall Dungeon. Like Jungle spiders, they do not show on the mini-map.
