Reedback Crabs
What it is
A territorial crab of swamp and mangrove banks. It has a mudstone shell, a reed crown and big bronze claws. It warns before it strikes.

How to get it
Reedback Crabs spawn alone on shallow wet banks with solid footing and open sky. They need swamp or mangrove swamp. Two crabs close by stop more from spawning.
They don’t spawn on Peaceful. You can turn them off with the reedback_crab wildlife setting.
A defeated crab drops 1 to 3 Clay Balls. Clay goes into a Reed Rattle and a Bastion Poultice.
How to use it
Come within 5 blocks and the crab notices you. It stays near its home bank.
| Phase | What you see | What to do |
|---|---|---|
| Warning | Claws rise and the crown shakes for 2 seconds | Step sideways, or answer it |
| Sweep | Both claws swing through the lane in front of it | Stay out of that lane. It does not turn to follow you |
| Recovery | Claws settle for 3 seconds | Move away or attack |
The sweep deals 5 damage. Walls block it. Leave its territory and it stops chasing.
Tips and counterplay
- Sneak past while staying more than 2 blocks away and it ignores you.
- Tidebreath calms it for 10 seconds.
- Any Wind hit knocks it into recovery.
- A crouched Reed Rattle calms it during the warning.
- These answers share a 10-second rest on the crab. Attacking it breaks the calm.
- Plant your Moonreed garden away from its bank.
