well Guys, I have a great question to all.
at the begin of this year I bought in this page the book necromancers almanac, and I found a feat that it name is Shoulder throw, it says that if you are grappling an oponent, you can throw it in a adjacent square and you inflict your unarmed damage plus 1d6 of damage and your oponent is prone.
This night I found another feat, the name of that feat is ki diversity, it have a 4 powers, one of them is the Bone Crusher, it says that you can spend a ki point as a swift action and if you make a trip or disarm an oponent, you make a damage equal your unarmed damage...
my question is...
Can I spend the ki point to make double damage?
Looking at the text, no.
Shoulder throw works on a grapple. Ki diversity's bone crusher works on a trip or disarm, so you cannot use the two on the same action no matter what.
