Clash!

Stabbing a Zombie with the spear's range bonus

The Spear's stab attack will crit when fully charged.

There is also a first person animation, but it is hard to convey in an image.

Spear enchantments

Spears can also receive Unbreaking and Mending, but all things with durability can, so I left them out.
