K.O.

K.O.

Class	Weapon Mod

K.O. is a Blunt weapon mod that makes each swing heavier and slower. It adds a flat damage bonus to the weapon. Hits on Stunned enemies gain a chance to knock them down. In return, attacks cost more Stamina and come out slower. It suits a Body build that hits hard with clubs and hammers and can afford fewer, bigger swings. K.O. is available from the early game, since melee weapon vendors can stock its lower tiers.

Effect

K.O. raises the weapon's damage by 25% at every tier. It cuts attack speed by 20% at every tier.

The Knockdown chance against Stunned enemies grows with tier. It is 15% at Tier 1 and 40% at Tier 5. The extra Stamina cost shrinks as the tier rises. It is 25% at Tier 1 and 10% at Tier 5.

How to Get K.O. Guide

Check melee weapon vendors, which sell lower tiers.
Skip time by a day and check again if it is not on sale.
Combine a matching pair at the crafting menu to raise its tier.

Upgrades

K.O. comes in Tiers 1 to 5. A matching pair of the same mod and tier can be combined at the crafting menu into one copy a tier higher. A mod can only go on a weapon of the same tier or higher. Once installed in a weapon, the mod stays in that weapon.

Character Builds

K.O. belongs on a Blunt weapon in a Body build. Wrecking Ball and Quake each lower the Stamina cost of Blunt attacks, which offsets the higher cost of K.O. Quake also adds attack speed with Blunt weapons. Aftershock restores Stamina for each enemy hit with the Quake slam.

Barbarian is another Blunt weapon mod. It adds damage against Stunned, Staggered and Knocked Down enemies, including those that K.O. knocks down.
