I have a few questions: Is there a way to change where you spawn in the nether? Is there something to auto harvest and auto plant crops? Best way to get ender eyes and blaze rods?
Well question 2 and 3 depend a bit on what modpack you are playing, but question 1 I can answer. Your nether portal is generated somewhere in the nether (multiple players are assigned to the same portals), and that is where you spawn in the nether. You'll have to travel when you are going to other places, so no, you cannot change the spawn point.
I don't know how far you've progressed, but for harvesting crops I'd use a farmin station from ender io and for the blaze rods and ender pearls, perhaps mystical agriculture.
I'm very near the beginning, like I can get into the nether, but will die instantly. might be able to eventually use the farming station once my mob thing works Edit: NVM I can't do that
