Blood Demon Art · also called Blood Sickle
Blood Manipulation
Blood Manipulation is the one art tied to a weapon: its moves only appear with Sickles in hand. Any Sickles will do, including the Blood Sickles that Gyutai drops beside the art's last move.
It was cut back hard in the first balance passes, and one of its players describes it as gutted, though On Slaught got a small buff against bosses since.

Hovering a Blood Manipulation key mid-fight shows its name: On Slaught, the C move. Both Blood Manipulation Mastery and Sickles Mastery fill.

The five moves

- XRampant Arc RampageMastery ? · Points 66A domain of blood that keeps expanding; reportedly you cannot be hit out of it. An early balance pass reportedly removed its final-hit guard break.
- COn SlaughtMastery ? · Points ??Dash forward; hitting someone triggers a stun. One player calls it the art's best move. Spelled
On Slaughtin the game. V0.182 raised its damage scaling by 10% against NPCs and bosses. - VRotating Blood ScytheMastery ? · Points 1212A vortex of spinning blood scythes that pulls targets in and stuns at the end. Reportedly lost 35% of its damage early on, and its stun is no longer a strict one.
- BCircular SlashesMastery ? · Points ??A flurry of slashes that, by one player's account, locks on to anyone near you. Also needs a Gyutai kill.
A question mark marks a number still unknown for this art. On Cryokinesis, where the whole tree is known, the moves ask for mastery 14, 27, 40 and 53 and cost 3, 6, 9 and 12 points. The two extra keys on the Sickles row, N and K, are the Sickles' own skills, Execution Scyther and Scyther Vortex, not part of the art. How mastery fills is on the mastery page; the fastest ways to raise it are on mastery farming.

Tab Character, Blood Manipulation, Sickles, Cutlass and Shabana. Rotating Blood Scythe costs Skill Points 12.

What players ask about Blood Manipulation
- I unlocked Blood Manipulation but have no moves. Why?
- You need Sickles in hand. With fists, Claws or War Fans the art is learned but shows nothing.
- I killed Gyutai 30 times and still no Blood Sickles.
- At 7% a kill, about one player in nine goes 30 kills without them. Plain Sickles from Hoyuzo carry the art just as well; see weapon compatibility.
- Was Blood Manipulation nerfed?
- Yes. Early balance changes reportedly cut Rotating Blood Scythe's damage by 35% and took away its strict stun and the guard break on Rampant Arc Rampage. The details are on the updates page.
