Acquisition

While an Assassin's Critical Strikes attribute increases your chance of getting a critical hit greatly, using this skill can still be chancy unless you have a way of ensuring an even distribution of critical hits. Fortunately, Critical Strike, Malicious Strike, and the Warrior skills Wild Blow and Decapitate can provide critical hits on demand.
Critical Eye and Siphon Strength, which both increase the Assassin's critical hit rate, are also useful, though less predictable.
Combines well with Way of the Assassin.
Beware Soul Barbs or other such anti-enchantment hexes while under the effects of this enchantment, as each critical hit will count as a reapplication of the enchantment, and will trigger the effects of the hex.
