По теме: должно пробивать детер Чип Шотом и шивом, насчёт второго - только должен КП прибавляться, про дамаг не знаю,
С wowwiki:

Though it is not explicitly mentioned in the tooltip, it has been confirmed many times that Shiv cannot be dodged. It may also be unable to be parried or blocked. This makes it useful in PVP situations when your opponent is low on life and uses a temporary avoidance boost (such as Evasion or Ghostly Strike).
