So... Just to get exposure on a fire farm design I tweaked from W il's design from 4 years ago.
This fire farm design works for both pigs and bunnies, and especially helpful for Webber / Wurt / Wortox mains imho.
Just to clarify on a few things:
1. I took into account the accessibility of materials required for the farm design, and this design is by far the cheapest way to do it (eg. torch vs fire staff, watering can vs ice staff)
2. I used ropes stacked one by one to emulate the stacked fire damage ticks but idk if there is a difference for 1 rope or a few ropes stacked together, so feel free to experiment and let the community know if there's a cheaper way to do this.
3. I didn't realize that the burn ticks for minisigns were changed as of update 475356, though it's still not an efficient enough farm imo, since the fire spread for minisigns are way too slow for this design, and may cause most of the minisigns to burn up before the pigs / bunnies get killed. I didn't experiment on minisigns though, so I do appreciate any feedback from anyone who does.
4. This fire farm design can only fit a maximum of 25 pigs / bunnies since any number more than that will make the farm uncontrollable. I personally feel comfortable with 20 pigs / bunnies per farm.
