The Scarecrow's Sickles are a powerskill exclusive to the Fatal Falls DLC which mimics one of the attacks of the Scarecrow. Their damage increases with each hit they make on an enemy while active.
Details
Special Effects:
When used, two sickles are thrown into an arc on both sides of the player. They come back to the player after two passes.
If they make contact they disappear and go on cooldown. Dodge rolling through them will prevent them from disappearing and allows the player to keep them active for longer.
Each hit from this skill increases the sickles' damage. After the fifth hit, each attack deals critical damage.
