CATCH

If you are proficient in the catch skill, you will have a chance of catching weapons thrown at you providing that you also have skill in throwing that weapon yourself. For example, if someone is throwing a dagger at you, you will only be able to catch it if you are proficient in catch AND in dagger throwing (and even then, your chances will be slim). Should you succeed however, the item will go into your inventory.

If you are skilled with archery and are good with catch, you will also be able to catch an arrow shot at you every once in a blue moon.

Note:  If you do not have any hands free, do not expect to catch too many
       projectiles.  Also, should you happen to have BOTH hands free, your
       chances of catching will be much better than with just one hand free.
