I would definitely want n4e4 in there at a bare min. Once the rider dies, the spider has a ton of hps and can really benefit from regeneration. That also helps keep afflictions down.

E4 is also key as fatigue can bring down even the best sc. In fact that is how I typically kill sc's.

Given their low mr without a rider though, and the number of s races in the middle era, maybe a s9 n9 e4 bless is the way to go.

And if you run into ethereal right off(ermor) use flaming arrows. Flaming arrows has to be high on your list as machaka I think in any event.
