好消息，其實還剩下一抓
RotG:
A creature can choose to treat its unarmed attacks as its primary
attacks and its natural weapons as secondary attacks. (This
method is normally used to add weapon attacks to a natural
attack routine.)
The creature must make all unarmed attacks
with its primary limb, which prevents that hand from being used
for a natural attack such as a claw or slam. It uses its full base
attack bonus for the natural attack, gaining additional attacks as
normal for a high base attack bonus, and adds its full Strength
bonus on damage rolls. Of course, each of these attacks
provokes an attack of opportunity if the target is unarmed
(unless the creature has Improved Unarmed Strike). However,
its natural weapons all become secondary attacks, taking the -5
penalty on attack rolls (or -2 with the Multiattack feat) and adding
only half the monster's Strength bonus on damage rolls.
ps 請假裝承認WotC的咚咚很邏輯、很精確、很前後一致罷，不愧是官方規則欸
