[Bug] Upward polearm attacks are not parryable

[Sodapop]

If you do not have a shield, the new upward attacks with polearms cannot be defended against. This makes players with spear and shield, or even just a polearm alone very powerful, as mobs without shields cannot stop your attacks. However, mobs with the same cannot be 'held' like normal, unless you want to take shield damage.
