Q 257: The Sugliin weapon from Frostburn states "this weapon is so unwieldy and heavy that making a single attack with it is a full-round action."
Charging is a special full-round action that allows you to move up to twice your speed and attack during the action.
Can someone without the Sugliin Mastery feat charge with a Sugliin, or does the extended attack time prevent this?
Bumpity
I would say the latter.
normally, a single attack is a standard action. However, there are 2 times when this is not the case: iterative attacks and on a charge.
Charge lets you double-move and make a single attack.
You can't over-run on a charge, because that is a standard action.
As a matter of fact, you can't do any kind of special attack on a charge that is defined as being a standard action.
Full-round action > Standard action. If you can't do a standard action, then a full-round action should be out of the question.
sorry for the verbosity ... just wanted to be very specific.
For a little demonstration, go outside and try it yourself.
1st, take something that would be a suitable analog for a sword (if an actual sword is unavailable) - a broom handle will do - and then go charging 60 toward a tree and swing.
2nd, take a friggin' tree branch, and do the same thing.
Let me know if you can tell the difference. I think you'll see that the extra feat is warranted.
