Obedience is the rune word 'HelKoThulEthFal' for polearms in Diablo II: Lord of Destruction. With extremely high damage, 40% crushing blow, and an enchant proc which adds a large attack rating bonus, all alongside 40% faster hit recovery, as well as a defense and resistance boost (useful since the wielder will not be wearing a shield), Obedience is certainly an excellent way to level a playing field in Hell Difficulty, all for two common runes and three runes that are not at all hard to obtain. As a polearm, this is equippable by Act 2 mercenaries, and is one of the best weapons available for them without needing to pay an arm and leg for. The decrease to fire resistance also can come in handy for builds that invest in fire skills.
