Newbie Question for Snatch

[sunnyangel]

Is there a limitation to what buffs can be stolen? Or any buffs can be stolen by snatch / Pillage? For example, many years ago, there are buffs can be casted on others, and there are skills that are only self buffs. Can Snatch/Pillage steal only those buffs that can be casted to others? Or they can steal also those self buff skills?

The only skill I remember not being able to snatch was defender's blunt mastery at the same time as templar's blunt mastery (which also didnt work when defenders could cast it on others) just give it a shot most skills are snatch-able.
