My first is in wield, sever bones and marrow.
My second is in blade, forged in cold steel.
My third is in arbalest, and also in arrows.
My fourth is in power, plunged through a shield.
My fifth is in honor, and also in vows
My last will put an end to it all.

What am I?

A word I know, six letters it contains, subtract just one and twelve remains.

The first is a person who lives in disguise who deals in secrets and tells nothing but lies.
Then think of a letter that’s last to mend the middle of middle and end of end.
Now think of a sound which is often heard in search of every unknown word.
Put it together and answer me this, which creature would you be unwilling to kiss?
