Only on shards where an EM item got lost, then duped (a portable version of her entrance).
However, the actual route isn't all that complicated, unless you're trying to lead a pet there on foot.
- Go into underground, and through the secret door to right.
- Run past the rotworms (and blood ele) to the teleporter (of, if a gargoyle, fly across the broken bridge).
- Run past the abyss entrance, go right across the bridge, north through the goblins, then turn hard left when you enter the room with the spiders.
- Run through the corridors, turning south when you reach the lucky coin pool, then back west and north through the eles, beetles and spiders. The entrance is at the end. And, you can recall out when you're done, and not have to face the gauntlet going out.
As DJAd mentions, the big draw is the Tangle, not the regular loot from the spider herself. Some would say that the Tangle is enough, especially in conjunction with using her to train pets, for a tamer (not as fast as the crazed mage, but at least there's actually something potentially worth getting while training).
