Slayers 2 Blood Demon Arts: all nine compared

The game itself calls them Evil Arts: Muzan’s roll line says random Evil Art, and the shop item is Reset Evil Art. There are nine, Reaper included: a Reaper Orb comes out of Muzan’s roll like the others. The fighting style with a similar name is a different thing, called Reaping Blades (see fighting styles).

You get one in two ways, and both end in an orb: roll at Muzan’s lair once you are a demon, or take an orb from a boss chest. Crushing the orb starts that art’s core training, and finishing it unlocks the art (the Cryokinesis core walkthrough shows one).

5 Spins ( 5 Free ), then Roblox disabled rolling for you. Muzan: You have 30% chance of rolling nothing, and 70% chance of rolling a random Evil Art, good luck.

The nine side by side

Three tier lists sit side by side, not averaged. Each demon boss in the table drops one move for an art, at 5% at launch, and the v.09 patch raised every boss skill drop rate by 5% since.

All three put Shockwave in S; Ice Manipulation is S at two and A at Pro Game Guides. The widest splits are Blood Manipulation, Pyrokinesis and Obi Manipulation; Obi and Pyrokinesis run from S at Pro Game Guides to C at Destructoid. Tamari is last or joint last on all three. The breathing styles ranked alongside these are on the tier list page.
A boss’s scroll line names the art it needs when you lack it: Nezura’s says Missing Pyrokenesis (the game’s spelling), Datai’s says Missing Obi Manipulation, Akazo’s says Missing Shockwave, and Gyutai’s says Missing Blood Manipulation. Domae’s scroll is Cryokinesis’s last move: that node in the tree asks you to Defeat Domae. Since the v.09 patch Domae’s, Akazo’s and Nezura’s scroll lines read 10%.
Gyutai also drops Blood Sickles at 7%, a weapon, separate from the scroll. Blood Manipulation’s moves only work with Sickles in hand, while Shockwave uses bare hands, Claws or the Gauntlet; which weapon carries each art is on the weapon compatibility page. Full drop lists for every boss are on the bosses page.

Nezura's health bar with the drop list printed under it — `The Pyrokinetic Demon` `Nezura`: the health bar, and under it every drop with its chance.

Datai's health bar with the drop list printed under it — `The Obi Demon` `Datai`: the health bar, and under it every drop with its chance.

Akazo's health bar with the drop list printed under it — `The Shockwave Demon` `Akazo`: the health bar, and under it every drop with its chance.

The developer’s own previews

Ouw Productions uploaded a showcase for most arts before release. They show the moves as designed; balance patches since then have changed some numbers.

Rolling one at Muzan

Become a demon first. The roll is only offered to demons.
Ring the Biwa Bell, talk to Muzan in his lair and pick Give me your power. The Muzan page covers the lair and its reputation toll.
Muzan states the odds before you spend anything. At launch he quoted 30% nothing and 70% a random art; recordings from a few days later show 50% and 50%. He does not say whether the nine share the winning half evenly.
Spend spins. A new demon starts with 5 Spins ( 5 Free ). One roll reportedly takes three spins, and getting one specific art may take around 57 rolls.

The same spin panel in another player's video, showing zero spins — The same panel and odds line with no spins left: `0 Spins` and `Insufficient Spins`.

The spin panel scrolled to its three largest Robux packs — Scrolled down: `250 Spins` `480` (`600` struck through), `100 Spins` `216` (`270` struck through), `50 Spins` `120` (`150` struck through).

Robux packs on Muzan’s panel
Spins	Full price	Lower price shown
1	5	none
15	60	48
25	90	72
50	150	120
100	270	216
250	600	480

Every pack but the single spin shows a lower price beside the struck-through full price; prices may differ in your game. There is also an Ore tab. The first four packs match the clan roll panel; how spins, codes and Ore fit together is on the spins page.

Paying Robux for rolls is hard to justify, since bosses drop art orbs for free.

`Roblox disabled rolling for you`

This message on Muzan’s panel, pictured at the top of this page, stops you rolling at all. In some countries the same block hits clan spins. If it happens to you, the boss orbs below are the other route to an art.

Orbs from bosses

Bosses reportedly drop art orbs, Blood Manipulation among them. Beat the Thunder Trainee mini boss, for example, and a Reaper Orb can appear beside you with a Claim prompt.

An orb is not the finished art. You use the item to start that art’s own quest, much like unlocking a breathing style with a trainer; the trainer version is laid out on the breathing styles page. Every orb comes from chests at the same odds; the orbs page maps those chests to bosses.

A demon player at night beside a glowing orb with a Claim prompt, after beating a mini boss — At `Lv 132`, beating `Mini Boss` `Thunder Trainee` pays `+108 Blood Manipulation Mastery` and `+10 Demon Progress`, and leaves a `Reaper Orb` with a `Claim` prompt.

Resetting your art

The price

Reset Evil Art is in the in-game shop. It costs 7 Ore, or 100 Robux (80 for Roblox Plus members). Reset Breathing is 7 Ore in the same list. The ARTRESET code gives one art reset free.

What you lose

Since the V0.182 update an art reset refunds the skill points you put into it, so those are not lost. Mastery for the old art still goes.

Then roll again

After a reset you are back at Muzan’s panel, facing the same odds Muzan quotes, 50/50 in the latest recordings. If you already hold a useful A-tier art, keep it while you progress rather than rerolling.
