Overall Concept: Simple-Dash-Slash
I was thinking of how this could be radically different from the other techniques in playstyle, and I came up with this concept.
Simple Domain (different styles using crouching, chant, and flow) combined with dashing and then the actual slashing!

Passives:

In the "Cursed Energy" tab, Simple Domain is now a completely different move.
Simple Domain turns into "Mastered New Shadow Style Simple Domain"
Now, on use, activate a Simple Domain similar to the trait of "complex domain," but for only 3 seconds; the range of the simple domain is the same as a normal player's crouch simple domain (4 blocks, counting the center block). Damage against innate moves is reduced by 33%.
When opponents are inside the simple domain radii, cursed energy regeneration is halted.
The whole point of this is to combine Simple Domain with your innate moves.
Crouch: The regular crouch simple domain is kept, but now with a 2-block bigger radius.
Chant: Multiply the damage of any combined moves by 1.25x.
Flow: Activate this for 6 seconds instead of 3.
CE Cost: 50

New Shadow Style Katana
While holding any sword/axe, it will be reskinned as a Katana. Use RMB to sheathe and unsheathe it. All abilities will work while sheathed.

Innate Abilities:

Ability 1: Batto Sword Drawing
An extremely fast but simple single Slash in front imbued with Cursed Energy, you slide 2 blocks while using.
Chant: More damage.
Combined with Dash, does more damage, and the cooldown of Batto Sword Drawing is reset so you can immediately slash again!
Universally combined with Simple Domain, it becomes a sure hit in the simple domain area, so you don't need to aim it.
Cooldown: 5 Seconds.
CE Cost: 50

Ability 2: New Shadow Style Dash
A simple, short, dash move.
Shift + Dash to launch with a better upward trajectory.
Combine this skill with other moves for extra effects!
Dash, then "Slash" to get the combo effect.
Cooldown: 7 seconds
CE Cost: 50

Ability 3: Evening Moon Sword Drawing
Simply put, it's the 'Slash Barrage' ability.
Chant this move for extra damage.
Must be combined with Simple Domain to have an effect.
With normal/flow Simple Domain: Inflict a flurry of slashes in the whole simple domain. Nullifies an additional 27% of damage from other innates.
Combined with Dash: Stuns the opponent for 1 second.
With Chant Simple Domain: Deflects 100% of attacks that enter the Simple Domain; however, the user is not actively slashing, so this is a purely defensive form.
Combined with Dash: If anything gets deflected, after the Simple Domain runs out, Dash's cooldown is reset.
With crouch Simple Domain: The user becomes immobile, but the slashes deal more damage. (and have more range because of crouch simple.) Nullifies an additional 17% of damage from other innates.
Combined with Dash: After 1.5 seconds, the simple domain will expand, and the sure hit becomes bigger by 4 blocks (massive). The player will then AUTOMATICALLY slide to each opposing player inside so the slashes can hit and the slashes become faster, but with less damage. The larger Simple Domain would re-apply Simple Domain for 2 seconds, which extends the effect so it doesn't just go instantly after u use the combo.
Cooldown: 10 seconds.
CE Cost: 150

Ability 4: Hazy Moon
On ability press, feint opening your crouch simple domain (VFX is the same), but it disappears right after the crouch simple domain reaches around the caster. At this point, you can use a powered-up Dash-Slash combo as Dash's cooldown is reset, it launches you farther, and the subsequent Batto Sword Drawing or Evening Moon Slashes becomes stronger.
Flow: Make it look like you are opening a flow simple domain. Same effects empowering the next combo.
Chant: Leap into a flying knee kick which breaks guard (specifically breaking abilities like Toji's block, Kashimo's Counter, and the Parry from CF) and kick again, knocking enemies back and stunning. Empowers your next dash-slash combo. (16-second cooldown)
Cooldown: 12 seconds
CE Cost: 100

Ability 5: New Shadow
Pressing this ability will let the caster use their following move without cursed energy cost and ignoring the cooldown.
Chant+Flow: Set all cooldowns except Maculation to 0 at a higher CE cost.
Shift can let you choose between New Shadow and automatic programming
Cooldown: 15 seconds
CE Cost: 200

Ability 5 Alternate Ability: Automatic Programming
This is a toggleable move similar to flow and max output, so it stops cursed energy recovery; however, this will also passively drain your cursed energy.
What it does is that every time the user is inside a simple domain, the user will automatically enter evening moon sword drawing when something enters the simple domain radius. Gain additional resistance to damage when things enter your Simple Domain; however, the slashes from Automatic Programming deal less damage than regular Evening Moon Sword Drawing.
If this is active, you cannot use New Shadow (you must toggle this off and then shift to select New Shadow)
CE Cost: Drains like a Domain Expansion

Ability 6: New Shadow Style Simple Domain: Maculation
Upon using this ability, create a web of Simple Domains that have the same area as a Domain Expansion.
Gain an additional +17% Damage resistance from innate attacks and 33% from melee and sword attacks.
This acts as a long-lasting massive Simple Domain, so all attacks have the Base Simple Domain combo effect. (They will have a range limit so it doesn't cover the whole Maculation; the range of moves would be around the size of Crouch Simple Domain, so it's still boosted range.)
Dash's cooldown will be reduced to half every time it is used in Maculation's Area of Effect.
When Maculation is called off, you will get burnout, like a Domain Expansion, but not nearly as long as a domain expansion since you have no curse technique technically, and this isn't a domain.
31 Block Radius.
If the caster already has a simple domain active, expand that simple domain into Maculation at less CE cost than just using this ability without it.

CE Cost: Upfront 500, then drains like a Domain Expansion

Special Binding Vow Change: Complex Domain
If you are New Shadow Style, Complex Domain's function will change.
Complex Domain will now let you bypass Domain barriers and let you enter Domains by using Simple Domain. You cannot exit the Domains after entering.

Thank you, you made it to the end!
