Shadow spiders are one of few monsters that are hidden on the player's minimap. If a player initiates combat with one, it will drain their Prayer points by half of the current amount, rounded up. If a player is in combat with them over a long period, they will continue to drain the player's Prayer at set intervals. They can never take away a player's last prayer point.

Shadow spiders except those found in the Wilderness are unaggressive to players with a combat level of 105 or higher.
