Mastercall

Mastercall

Mastercall is a mod about Servants: legendary heroes you call into the world through an ancient summoning ritual.
They are not pets that simply follow you around. Each one has their own personality, fighting style, Noble Phantasm and way of reacting to how you treat them.

---

✨ How to start

1. Craft Ritual Chalk (calcite + amethyst shard) and hold right-click on the ground to draw a summoning circle, line by line.
2. Place a Servant’s catalyst in the center, then Shift + right-click with an empty hand to begin the ritual. Every Servant answers only to their own offering.
3. The ritual draws on your mana: two days’ worth of the Servant’s upkeep (free in Creative). A chant, rings of light, a pillar of radiance... and the circle bursts as your Servant steps out.
4. A Contract Book and Command Seals appear: that’s your bond.
5. Not sure what to do? The Book of Summoning explains everything, with recipes and pictures.

You can have only one Servant of each kind.

🗡️ The Servants

👑 Gilgamesh (Archer): new!
The King of Heroes, owner of every treasure in the world, and he never lets you forget it.

• Gate of Babylon: golden ripples open in the air and fire swords, spears and ancient blades. The more dangerous the enemy, the more gates he opens. The more he’s hurt, the more blades pour from each.
• Enuma Elish: when his wrath and the sword Ea are both at their peak, he splits the world itself.
• He is not your pet. He watches who actually fights beside him. Earn his respect and he will listen, share his treasures and maybe even call you by name. Hide behind him, and he’ll call you a mongrel and ignore your requests.
• The most expensive Servant to keep: 500 mana a day.
• Catalysts: a gold block, a diamond block and an emerald block.

Ori (Shielder, original character): new!
A former night nanny who was once called a demon. He deals no damage at all: he fights with fear.

• Weaves illusions of Servants he has seen with his own eyes. They fight like the real thing but hit for nothing.
• Frightens mobs until they flee, and may even stop a weak heart.
• The only Servant who is truly afraid: he panics, breaks into hysterics and hides from a Gorgon’s gaze behind a crowd of his own doubles.
• Always carries children out of harm’s way.
• Noble Phantasm True Demon (False): the target sees what they fear most.
• Catalysts: a ghast tear, any bed and an amethyst shard.

Sasaki Kojiro (Assassin)
Not a killer from the shadows but a gatekeeper swordsman with an impossibly long blade.

• Long, heavy strikes that cause bleeding. He parries blows up close and dodges everything else.
• Tsubame Gaeshi: three cuts in the same instant. You can’t dodge it. You can parry it, but your weapon will shatter.
• Catalysts: a wooden sword, iron and a compass.

King Protea (Alter Ego)
A gentle, endlessly hungry girl who grows the more you care for her. Feed her, earn her affection, maybe even give her a ring... and one day she may become something far larger than a companion. She is afraid of being left alone.

Frankenstein (Berserker)
An artificial girl brought to life by electricity. She only says “uu”, but she understands almost everything.

• Trust grows with time together, care and flowers. She forgives a stray hit more easily than anyone.
• Battle drives her into Berserker madness: temporary HP, crushing blows, leaping lightning slams. At its peak she stops listening to orders and smashes through walls.
• Leave her alone for too long and she breaks down. Wall her in and she will break out.
• Weapon: the mace Bridal Chest. Noble Phantasm Blasted Tree: a colossal tree of lightning that kills even a Warden, and her as well.

Medusa (Rider)
A cold, silent fighter with chains and a blindfold. She doesn’t trust easily. Earn it, and she’ll fight beside you, pull you out of danger and even let you ride her Pegasus. Her gaze is better left unseen. Keep her well fed with mana, or she will go hunting on her own.

Ereshkigal (Lancer)
The proud goddess of the underworld, bound to a fragile body of clay. Her spear tears souls out of enemies and keeps them in Kur, and on your order she raises them as an army of the dead. She insists she doesn’t care about you at all, and she is very possessive of what she considers hers.

Artoria Pendragon (Saber)
The King of Knights, armed with a blade no one can see. She fights with grace and discipline, and she watches how you fight too. Live by the knight’s code and she will share her secrets. Betray it, and you will learn what a king’s disappointment means.

Medea (Caster)
A witch from the Age of Gods, graceful and dangerous, wrapped in a flowing cloak. She counts every blow you land on her, and she never forgets.

• Turn your base into her lair: inside it she flies and teleports, hostile mages fall silent, enemies can’t find the entrance, and after every fight she rebuilds everything that was destroyed.
• Spells: fire, lightning, ice and a shield that absorbs magic, strong enough to stop even /kill.
• Her dagger Rule Breaker dispels any magic. Noble Phantasm Hecatic Wheel: a sky covered in magic circles, raining lasers for a full minute.
• Hurt her too often, and once your last Command Seal fades... she may break the contract herself.

Mash Kyrielight (Shielder)
A shy girl with a giant shield, sleeping in a frozen capsule high in the snowy mountains. Artoria can sense it when you are close enough. Fuel the capsule like a furnace and Mash will wake up.

• Her shield is a real wall: mobs can’t pass it, you can stand on it, and it blocks arrows, Guardian beams and even the Warden’s sonic boom.
• She always stands between you and danger, pulling enemies onto herself.
• Noble Phantasm Lord Camelot: a wall, a fortress or a full dome. Its strength depends on her heart.
• Give her a ring, and she will not let you die, even if it costs her everything.

⚔️ Combat

• Class advantages work like in FGO: Saber beats Lancer, Lancer beats Archer, Berserkers hit and take more from everyone.
• Magic Resistance ranks: magic hurts high-ranked Servants far less, and a Gorgon’s gaze only slows them. Frankenstein’s resistance grows with her rage.
• /enemyservant <servant> summons a hostile Servant to test your strength.

🔮 Mana and Magic

• On first join you choose your magic circuits: Classic, Advanced or Broken. Each plays differently.
• Mana refills when you sleep. Servants need daily mana, and you decide how much each one gets. A starving Servant grows weaker.
• Drain your circuits completely and your vision darkens and your stomach turns. Each Servant reacts in their own way.
• Cast spells yourself: hold the key to draw the circle, release it to cast.
  • Fireball (H) and Lightning (J) are available from the start.
  • Ice Spikes and the Absorbing Shield (V) are learned from rune books.
• Mana transfer (R): pour your mana into a Servant mid-fight to heal them or recharge their Noble Phantasm.
• All keys can be rebound in the magic window (K).

📖 Contract Book

Every Servant (except Mash) has their own Contract Book. It can’t be crafted. If you lose it, just right-click your Servant with an empty hand.

• Their story and personality.
• A map of the places they have seen: click squares to mark a territory to guard. Guarded zones glow in each Servant’s colour.
• A list of creatures you have seen that are still alive: mark them and your Servant will hunt them down.
• Servant-specific orders, such as sending Ori’s illusions into a sector or having him weave a copy of a chosen Servant.

⚠️ Book orders are requests, not commands. A Servant may refuse, and each has their own reasons.

🩸 Command Seals

Every contract leaves its mark: three red seals on the back of the Master’s hand. Spend one, and your Servant obeys absolutely, wherever they are: come back, stay, fight, or unleash their Noble Phantasm. Use them wisely. They don’t come back easily.

💭 Servants remember

If a Servant falls, they can be summoned again, and they will remember you: everything you did for them, and everything you did to them. Kindness is rewarded. Some mistakes are never forgotten.

Servants also know each other. Keep more than one by your side and you’ll hear what they think of one another.

More Servants are planned in future updates.
