The Fangs of Apophis

This ancient knowledge that was taken from the sarcophagus of a sorceress of Apophis allows the user to summon great fangs from the earth to pierce their enemies. When hit by these great fangs the target is injected with a potent poison and paralytic. 

The target needs to make a CON save, taking 6d10 poison damage and becoming paralyzed for 1 minute on a failure, and only taking half damage on a save and not being paralyzed.
