I'm currently working on doing the runic altar challenge. For the most part the task is to automate every single ingredient used in any runic altar recipe. Most of the items are pretty straight forward with the exception of spider eyes. The only ways i know to get these without use of other mods is either a witch hut farm or a player kill on a spider. I dont like the first one because i dont want to build the system near a witch hut. An afk spawner Farm for spiders in my opinion defeats the entire point of having one big system for everything, since the only upside of that over multiple independent farms is to leave it running and not having to do anything. Right now my idea is to use tnt lit by a player-shot arrow to get the player kill drop without a player. This would however be absurdly complicated and laggy just to get spider eyes. I'm interested if anyone knows of another method.
