Fan of Knives
Fan of Knives is an area skill on a cooldown in which you hurl knives in a spiral around you, dealing high damage to all nearby enemies while briefly slowing them. As an instant all-around strike it's ideal for defusing suddenly surrounded situations, poking dense groups, or buying yourself some breathing room through the slow.
Among the runes, Assassin's Knives is valuable if you want to extend the range and hit additional distant enemies, considerably widening the area effect. If you instead need more control, Fan of Daggers stuns enemies hit for several seconds. For pure burst, Pinpoint Accuracy massively raises the damage at the cost of a longer cooldown, while Bladed Armor converts the skill into a defensive tool. So you can tune the skill toward range, control, or peak damage.
Knives Expert and Bladed Armor
Fan of Knives unlocks at level 14: 620% weapon damage within 20 yards on a 10 second cooldown, plus a 60% slow for 1 second. Besides Assassin's Knives, Fan of Daggers and Pinpoint Accuracy, there are two more runes. Knives Expert (level 38) removes the cooldown but costs 30 Hatred per cast, turning the emergency spin into a repeatable attack that depends on your Hatred. Bladed Armor (level 32) grants 40% additional armor for 6 seconds and is the common pick in practice. For the unlock order: Pinpoint Accuracy arrives at level 23, Fan of Daggers at level 44 and Assassin's Knives only at level 59.
The Shadow's Mantle
In The Shadow's Mantle, Fan of Knives is one of four skills whose damage the 2-piece bonus raises by 6000%, but only while you wield a melee weapon. The 4-piece bonus makes Shadow Power permanent and gives it every rune, while the 6-piece bonus focuses on Impale.
Ambush and Hungering Arrow
Ambush raises damage against high-health enemies, and a spin into a fresh pack hits exactly those targets. Hungering Arrow generates the Hatred that Knives Expert spends. Vengeance, Preparation, Smoke Screen and Strafe are frequent partners as well.
