Web Projection

Web Projection is the ability to project webbing from one's hands and create spiderwebs. This webbing is powerful enough to trap and contain adult humans and also prevents those trapped from teleporting.

About Web Projection
This ability can also be used to trap victims in an indestructible cocoon that preserves those trapped inside. This web also acts as a force field which can zap and knock back those who attempt to touch it.

Additionally, the Spider demon can use a voice echo by creating a web and projecting her voice through it.
