What characteristics does sentry inherit from weapon?

I know that as of 1.0.5 sentry does 175% dmg and no crit bit I was planning to try an (engineer) set up as I call it with focus on sentry as the main dmg dealer so I wanted to know what characteristics other than dmg does it take from the weapon (attck speed, life on hit, dmg converted to life, chance to stun...etc)?
