Discussion of the Necropolis faction.

It's not necessary to give every creature in the game (or something similar to a spider) the ability "Weave Web";).

The most obvious thing you can give a spider (or a spider-hybrid...) is the ability to transform from a Lich into a Vampire and bind an enemy to a spot with a web, wrap them in a web, and digest them with poison, then eat the enemy. In general, you can come up with many things.
