徒手攻击没有限制你的攻击部位，所以用脚摔是可行的
但是各种引发AO和不擅长并且这不是重点，重点是你的精通摔绊在用脚摔完后只能踩一脚而不是补上一剑
使用武器摔绊唯一的作用是“可以使用该武器来进行近战接触攻击来取代徒手近战接触攻击，而且也不会引发借机攻击。”
至于精通摔绊的效果：
“If you trip an opponent in melee combat, you immediately get a
melee attack against that opponent as if you hadn’t used your attack
for the trip attempt. For example, at 11th level, Tordek gets three
attacks at bonuses of +11, +6, and +1. In the current round, he
attempts to trip his opponent. His first attempt fails (using up his
first attack). His second attempt succeeds, and he immediately
makes a melee attack against his opponent with a bonus of +6.
Finally, he takes his last attack at a bonus of +1. ”
无论从说明还是实例都只提到了“makes a melee attack”，换句话说只要你手上拿着武器，无论摔绊是用什么进行的，你在之后都可以接着踩上一脚或者补上一刀，只是要采用等同于摔绊使用的攻击加值而已....
