Block animation.
The Ender Giant Sword, added by the Asgard Shield Addons mod, is a half-shield, half-sword (like all Giant Swords) that is able to totally block damage by right-clicking. In comparison to an unenchanted diamond sword (which does 7 damage), it does two extra damage (9 damage) on unarmored targets.

Trivia
- This sword looks like it came from "More Swords" mod, however, it isn't, since More Swords mod also had a specific enchant that can let you teleport with it for it, for free.
