This is Re:Cecilus, an addon for Re:Core (it also needs Re:Magic). It isn't an authority: it adds the two swords of Cecilus Segmunt, the Blue Lightning, Murasame and Masayume.
Let me know any bugs/suggestions by joining my discord server!
You can find the swords VERY RARELY inside the chests of dangerous structures (Bastion, Ancient City, End City, Trial Chambers, Stronghold, Nether Fortress). Only one of each per world, so once someone finds it, it's gone!
Drawing the swords
Hold right click on the sheathed sword (or press Y). Y puts it away, changing slot sheathes everything. One sword in each hand is the dual stance, and that's where Cecilus really is himself.
Murasame: she wants Flow Method at 100% (from Re:Magic), at least 2000 kills and full health. The first draw tells you the price, draw again within 10 seconds to pay it: two max hearts, for good. If you're not worthy she tries to possess you, and if she wins you stab yourself in a cutscene you can't skip. Yes, it kills you!
Masayume: no Flow needed, she asks for a dream. The first draw lets you pick one of four dreams, you fall asleep in the dream world of Re:Magic, draw again there and the blade comes out. Every dream has a deadline (days of play, 20 minutes each: 15 for strength, 30 for the world, 25 for wealth, 50 for legend) and if it doesn't come true in time Masayume kills you and you have to win her again. When it comes true she devours it and stays shut until you pick another one. Make all four come true and she's yours forever.
Corrupted souls: if you carry an Authority (Return by Death too) both swords refuse you at once. Murasame possesses you, Masayume throws you into the dream. Choose.
Gauges
Hunger (Murasame): rises with kills and blows. When it's not enough to pay a move the rest comes out of your life as Decay: blackened hearts that don't regenerate while you use the sword, and if they fill the whole bar the sword kills you.
Yearning (Masayume): rises as you move and hit, wishes spend it. At zero she devours your desire: 10 seconds of dead blade.
Focus: Blade Mode and Hyper Concentration burn it, at zero you come out dizzy. A kill in Blade Mode gives some back.
Fun: Cecilus puts in more when he's enjoying himself (the clouds on his kimono climb the cloth!). It rises when you hit and parry, falls when you do nothing or get hit. At the top: +40% damage and a third off cooldowns. Seven Cuts and Maximum Power need it.
Moves
Murasame
Left click-Demon Chain: three heavy cuts, the third throws a far slash that keeps cutting way past the target.
Z-Point Cut: look at something, you mark its "point" for 3 seconds, the next blow ignores armour, Flow and reductions and strips everything that covers it: buffs, shields, even the effects of Authorities.
X-Far Crescent: hold and release for a huge crescent that cuts through everything, projectiles and clouds of magic included (not blocks).
C-Contract Cut: cuts bonds, leashes, holds and masters of who's in front of you. Charm, mind control, Coercion, etc.
V-Scent Sever: for 8 seconds mobs lose your scent and stop targeting you. Hitting breaks it.
Masayume
Left click-Dream Flow: four light cuts with a wide hitbox, the fourth is a full pirouette.
Z-Wish: tap for the chosen wish, hold to open the wheel: Dream Step, Fortune (the next blow can't miss), Respite (breath and healing), Lucidity (Focus).
X-Intent Cut: interrupts what the one in front is doing: spells, charges, bows, a creeper's fuse. On you it cuts mana sickness!
C-Dream Step: look at someone within 16 blocks, you vanish and reappear behind them with a rising cut.
V-Awakening: you sink, then a whole turn with the arm out that hits everything around you and opens a ring.
Both swords (dual stance)
Left click-Combo: two twin cuts, then a spiral of three: seven in all.
Z-Cloud Cutting: three cuts on one key, none of them makes a sound as it leaves the blade. Tap: blink up to 25 blocks and whoever was on the line comes apart level a beat after you passed. Hold: a far horizontal cut flying 40 blocks. Hold even longer (you'll hear it and see the flash): a vertical cut that runs 70 blocks along the ground, opens a crack in the terrain and splits the real vanilla clouds in the sky!
X-Maximum Power: hold, when the blade turns white release it. Everything in the cone ahead takes huge damage and flies, weak blocks break (and come back). Needs Fun, Hunger and Yearning all together.
C-Twin Cut: an X on the target, it cuts its point and its intent at the same time.
V-Seven Cuts: seven cuts in one rush circling the target. Needs 30 Fun and spends it.
Always (any blade drawn)
B-Flash Cut: press looking where you want to go, you're already there and whoever was on the line can't move. The air behind you fills with cuts that all land half a second later.
Shift+B-One Thousand Cuts: crouch looking at a target within 16 blocks and you circle it in copies, cut it a thousand times,on the last cut the target falls into 1000 pieces. Bosses survive with a huge wound.
N-Lightning Step: a dash where you look, for an instant blows pass through you.
Right click-Parry: press just before the blow and it's cancelled, Cecilus takes you behind the attacker with a cut. Held it's a guard. Mashing shrinks the window!
U (hold)-Blade Mode: time nearly stops and the mouse is the blade: every quick stroke is a cut that way on the body in front of you. When it dies it opens along the cuts you made. Nothing is sliced the same way twice, every mob breaks along its own material!
Hyper Concentration: tap to enter, hold to go deeper, tap to leave. First the colours go (black and white), then the sounds, then everything: time around you nearly stops and nobody can react. From outside you're seen standing still. A cheap way to look at your own enemies from above ;)
Passives
Deflect: with a sword drawn every projectile from the front is turned back by itself: arrows, tridents, fireballs and skulls go back at whoever threw them, and what can't fly back (homing bullets, rockets, spells) is cut in two.
Cut a huge spell: the huge spells of Re:Magic (Al Goa, Ul Huma, Al Huma, Dona's drill) are not turned back, they hit you full... unless you swing (left click) just before one reaches you. The blade goes through it and the two halves veer to either side and land far off, smaller. Cloud Cutting splits them too!
Sky Step: jump in the air for a double jump.
Everything else
Every move's cooldown, costs and the rules above can be changed in the server config, and there's a lowGraphics option in the client config (no afterimages, no sparks, bodies cut in two pieces) for weaker PCs.
