The Arrow confusion

[Parawill]

The Arrow (tool-tip in action window) simply says "Increase target's attack speed by 10%." Attack Speed effects only Spells (Fire, Benefic, Adloquium, Shadow Flare, etc.) and Weaponskills (Heavy Shot, Heavy Thrust, Spinning Edge, Savage Blade). The active buff (when applied) says "Weaponskill recast time, spell recast time, and auto-attack delay are reduced" which is in reference to action abilities classified by either "Spell" or "Weaponskill."

The Spear reduces ability cooldowns upon use. Abilities include: Lustrate, Hallowed Ground, Bloodletter, Battle Voice, Apocatastasis, Hallowed Ground, Holmgang, Rouse, Spur, Enkindle, Barrage, Raging Strikes, Blood for Blood and alike.
