Giant Water Spiders are semi-intelligent creatures, and may be allies of lesser fey creatures such as nixies or sprites who live nearby. They make underwater lairs of webs and sticks which are open only on the bottom to allow entry without loss of air, as giant water spiders are air-breathers (though they are able to operate underwater for a full turn without suffering injury). They do not swim, but rather walk on the bottom, climbing rocks or vegetation to surface.

These are like their giant land-based cousins in most respects. They differ in that they do not build webs per se, rather; they build underwater lairs and carefully transfer air trapped in web-sacs to the lairs. They can hide within and wait for unwary swimmers, whereupon they will scuttle out and drag their prey down, poisoning them, cocooning them, and removing them to their lair to consume.

As their lairs are air-filled, if the creature is slain, these places may be used for one hour for creatures that require air to breathe.
