I've had mixed results with Bane Spiders. I think they are a good unit. Without any items, they have some weaknesses in their speed and fatigue rate and low defense. The high protection and coming with bane blades makes them effective assassins though - they can kill with just one scratch, even if they get killed themselves. They are expensive though and one needs to weigh whether it makes sense to add items, making an even greater investment for more effectiveness, or not. The use against some independents is a good one, I think. Also, against a human, using an occasional bane spider or two may get them paranoid and doing inefficient things to avoid or prevent assassination.

A stealth squad of them is expensive but can be fairly effective, especially if you have something else stealthy to include which is synergistic with them.

In some other cases, stealthy units with high protection are good to have, too.
