Which weapon works with your style or art
A breathing style or blood art only shows its moves while you hold a weapon that carries it. Breathing needs a katana, any katana, and not the Cutlass. Stone needs the Axe and Mace. Blood Manipulation works only with Sickles, Shockwave with bare hands, Claws or the Gauntlet, and Claws carry most of the other arts.
Breathing: hold a katana
Right after learning Wind, XenoTy is holding the Cutlass he won from Zuko. The key row shows only the Cutlass’s own skills and there is no Wind bar. Two seconds later he swaps to the plain Regular Katana from the shop, and the Wind keys and a Wind Mastery bar appear. Two players on r/Slayers2Roblox gave the same answer to people whose breathing moves would not work: use a katana, not the Cutlass.

Just after learning Wind, Cutlass in hand: three keys over the hotbar, F Z X, and a single bar, Sword Mastery Lv 41. No Wind bar.

Two seconds later with the shop's Regular Katana: the row grows to F Z X C V B and a second bar appears, Wind Mastery Lv 1 0 / 30.

Any katana will do
XenoTy casts Wind from a shop katana, not the Wind Katana. One player adds that the Sound Katanas, which have no tree of their own, work with whatever style you have. No katana card we have read gives a bonus to one style, so a style’s own katana looks like a stat choice, not a requirement; two commenters disagree on whether the Nightfall Serpent Katana helps Serpent. Where each katana drops is on the weapons page.
Stone is the exception
In footage from before launch its trainer would not teach empty hands and sent players for an Axe and Mace first, and Stone’s moves are cast with it. Whether Stone works from a katana, nobody has tried on camera. The Axe and Mace’s drop is on the Stone page.
Nobody has filmed a breathing style with bare hands, a Spear, a Tanto, the Gauntlet or the Shotgun, so we cannot say those do not work. The style list is on the breathing styles page.
Blood Demon Arts and their weapons
A demon’s art attaches itself to a weapon that carries it. MK unlocks Blood Manipulation while holding War Fans: no art bar, no moves. MK then picks up Sickles, and the moves and a Blood Manipulation bar come straight up. Each cell below says how sure it is.

Sickles in hand: eight keys, F Z X C V B N K, and two bars, Blood Manipulation Mastery Lv 35 and Sickles Mastery Lv 38.

Claws in hand, casting ice: Claws Mastery Lv 57 beside Cryokinesis Mastery Lv 69, and the last two keys padlocked. The creator's key letter is cropped off.

Blood Manipulation is the one art that needs Sickles. Plain Sickles from Hoyuzo work as well as Gyutai’s Blood Sickles, by two players’ accounts, and one adds the Damascus pair. revolver agz’s guide says every other art takes Claws or the Gauntlet and makes Blood the exception.
Shockwave is not an item in your bag, which confused at least one new demon. It goes on your bare hands; the player who asked tried fists and it worked. revolver agz notices Shockwave and Reaper players carrying Sickles as a second weapon; another player says it is for the Sickles’ own skills.
The Gauntlet is sold by the Black Marketer, and one player confirms demons can use it. Every weapon source is on the weapons page, and every art on the Blood Demon Arts page.

Gauntlet, Legendary: +2 (Additional Damage), 1.04x, +2.55 (Block Points). Source Sold by Black Marketer.

On launch day, one player answered that arts could not yet be used with weapons and that the developers planned it. Every Claws, Gauntlet and Sickles report above is from two days later or after, so if you read an early answer saying fists only, it is out of date.
Weapon skills live in the same tree
Most weapons you own add their own branch to your skill tree; the tab lists them, for example Flame, Spear and Cutlass together. With a demon weapon and an art, the key row runs to eight: the art on Z to B and, going by the Sickles and Claws frames, the weapon’s own two skills on N and K.
Some weapon skills are a boss drop you then buy in the tree. The Cutlass’s second skill, Quick Draw, is a 25% line on Zuko’s bar, and a player on Reddit confirms you must still unlock it in the tree after it drops. Hoyuzo’s Sickles skill is struck through with Missing Sickles until you own Sickles.

One tree for everything you own: the tab reads Character, Flame, Spear, Cutlass and Rengoku, with Flame Tiger UNLOCKED.

The Sickle Reaper Hoyuzo, 1445 / 1445, Rare Chest. Under the bar: Exp +360, Wen +160, Demon Horns x3 (50%), a struck-through Scyther Vortex x1 (10%) marked Missing Sickles, and Sickles x1 (3%) marked Lvl. 52.

Why the last move will not drop
A style’s fifth move needs three things: mastery 53 on that style, the move’s scroll from its Hashira, and the skill points. The scroll only drops for a player who qualifies, and the line under the boss’s bar tells you which part you are missing:
Must be SlayerYou are a demon, or have no breathing yet. (Demon arts print Must be Demon.)
Missing StoneYou have not learned the style or art this scroll belongs to. The same shape names a weapon: Missing Sickles.
Unlock PreviousYou know the style but have not bought the moves before this one in the skill tree.
Already HaveYou own the move already.
Unlock Previous is the trap. One player farmed Obari for over two hours before finding the node still asked for the kill. Buy moves one to four first, then farm. Even the first move is not free: after training it costs 3 skill points in the tree. How much mastery each move takes is on the mastery page, and which Hashira drops which scroll is on the bosses page.

Character, Stone and Himejima: Arcs of Justice struck through, Defeat Gyorei, Skill P.., REQUIREMENTS NOT MET, with 11 SKILL POINTS in the bank.

Rengu after the patch: Flame Haori Style 2 x1 (3%), Flame Katana x1 (5%), Flame Slayer Uniform x1 (5%) and Purgatory x1 (10%). No kill counter anywhere on the bar.

The scroll rate itself went up. Rengu’s Purgatory and Gyorei’s Arcs of Justice read 5% at launch and before it, and 10% on bars recorded after the v.09 patch, while the katana and uniform lines on the same bars did not move.
The 35-kill pity
Yes, for skill scrolls. The developer’s V0.135 change-log, open on screen in Balboabtw’s video, reads Added pity to skills unlock (35 kills). Players passed the number around straight away:
- AnalystPatient6284, on RedditPity is 35 kills; the asker then got his Thunder last move
- jonathan_rlopez, on Reddit35 kills; for Insect they had to kill the boss 35 times
- TrafalgerDAce, on Reddit30 kills
- KoujiEX, on YouTubeIllusory Light is guaranteed after 35 kills
- Rexon, on YouTubeThinks there is a pity of about 35, and notes it is not shown anywhere
No bar shows the counter, and nothing says whether it carries over between servers. The note covers skills only: nobody claims a pity for katanas or outfits. Two players report around 50 and 100 kills for one scroll; one of those was before V0.135, and kills made while the line reads Unlock Previous probably cannot drop it; whether they count towards the pity is unknown.

Blood Manipulation learned with War Fans in hand, then working once Sickles are picked up.
