It would be nice if the Fish trap would have it's own loot table that could be edited for specific packs.

Alternatively the Fish trap could maybe use the vanilla fishing loot table. This solution would make it future proof but would reduce the chance manipulation you can do now.

Loot table reference.

Fishtrap currently uses the vanilla fishing loot table. If you add bait it uses the fishing loot table with fortune.

:o thats cool. Time to automate that for some mending

Fishtrap also can be piped.

Exactly. This can be closed
