Forum:Weapon: Battle Shield

The Battle shield is an idea that came to me when i was fighting a gravios and got hit with it's fire beam. So the idea is a giant shield that has spikes on it. You would be able to guard any attack and stop a charging monster in it's tracks. Also you could bash it at monsters and charge at them with it but it wouldn't be as fast as a lances charge. The bad things are you wouldn't be able to move very fast and when guarding you would lose sharpness like the greatsword. However it's attack would be the same as a greatswords and it would do impact damage. Some way's this weapon would work is if you were fighting a monster and there was a heavy gunner on the team, the monster charges at him but all you have to do is stand in it's way and guard protecting the gunner and knocking the monster back. So what do you think?
