Beyond Dependency

THIS IS A MOD FOR MULTIPLE PLAYERS, NOT FOR SINGLEPLAYER!
Two players, different planes of exictence, yet dependent on each other.

One of you is the **Crafter**: you build, craft, farm and brew, but you can't fight and you can't break a single block. The other is the **Fighter**: you fight, mine and break anything, but you can't place a block, craft, or grow a thing. Neither of you survives alone.

How it works:
Pick your role for good on first join — every block one of you places or breaks is something the other finds
You're invisible to your partner: no name tags, no held items, no chat between roles. You read the world instead — blocks changing, torches appearing, footsteps in the dark
The Beyond Vault is the only way to trade: a shared chest split wood-and-gold on one side, dark iron on the other, with a glowing seam that tells each of you when something new is waiting
Bottle your own XP, fire a Signal Flare to call for help, or follow a Vault Compass that always points home
Swap roles with your partner, or solo-switch at a vault when they're offline
Scales past 2 players into matched teams of builders and warriors who never meet, with monsters that get tougher as more Fighters join

Every number is configurable — vault size, harvestable crops, switch cooldowns, XP costs, role balance, difficulty scaling — plus an optional Bound Hardcore mode where one death ends it for everyone.

The communication part is up to your ingenuity.
Chalk mod recommended
