In this video I explain how natural mob spawning have changed in 1.9, and its effects on all sorts of farms based on natural mob spawning. I also explain the implications of entity collisions bug, that I found, and how it can be used to create a perfect witch farm. In a perfect witch farm all the spawn attempts that happend in it have 100% chance of success. I am also explaining how to design such a farm, showing as an example, a skeleton farm, which while not the fastest, is ually still optimal (especially for a single witch farm settings where there is no need to worry about the mob cap).\r<br>\r<br>Moddeda aspects of the game (in MCP 9.18 (MC1.8.8) and MCP 9.24(MC1.9.0), used when appropriate):\r<br> - chilled monsters (demonstration purposes only)\r<br> - cranked up spawning (2000 ticks per second)\r<br> - carpet mod (mob spawn debug information)\r<br> - collision bug fix for 1.9 !
