Hello everyone and long time no see.
Since a friendly player informed me about the fact that nearly no new player knows of my Blaze farm, I thought to myself - how about a list with every existing grinder (and their warp).
Feel free to add a comment to this topic with your own grinder, the associated warp and the special quirks and features of it.
I hope this table helps new players to find their way around.
When we're at it, I'll start with my grinder right away:
Blaze grinder @ /res tp sblaze
The grinder is free to use and (of course) open to the public. It features a little bit over 100 blaze spawners and mob drops are turned off.
