―Rupert Giles[src]

Giles releasing an energy blast.

The Hammer of Govannon was a conjuration spell used to project a mass of concussive energy and blast it against a target. Like many spells, it had the appearance of a light bolt of energy.



Willow hit by an energy blast.

In May 2002, using the borrowed power of the Devon Coven, Rupert Giles used this spell in his magical duel against Willow Rosenberg after she became capable of countering his Binding Field Spell.[1]

After the end of magic, Willow was able to cast this spell during her time in Wonderland, striking and eliminating creatures that tried to attack her and her companions. However, its power manifested in a minor scale, and not always affecting the target creature.[2][3]

To destroy the Safe Zone force field, Willow cast the spell at the building housing its generators, freeing dozens of demons and vampires. She called it "Hammer of Govannon", and used it at a strength enough to tap her out.[4] When Faith mentioned preferring this spell, Willow explained: "Yeah, it's great if you have an hour to recover. Not if need to, y'know, be useful."[5]

Behind the Scenes

  • Differently from its first use by Giles ("Grave"), Willow pronounced this spell as "Escudo" in Season Nine. In Season Eleven, her pronunciation was "Excudo", indicating that the previous use (with an "s" in place of "x") was an writing mistake.
