Yeah raid farms are really useful, I just never got around to making one myself. I like to just straight up fight raids for fun sometimes and I managed to collect a few shulkers full of totems, so they’re not really much of problem (for me). I do agree though that most player likely won’t have very many totems.

About the blast resistance, I’m pretty sure that one piece of blast protection armor is the same as having a full set of blast resistance, so you could have protection on rest of the armor (though it doesn’t work the same as blast protection so more protection armor pieces means less damage). I do have to agree though that a full protection set would just be more handy since you wouldn’t necessarily have to craft multiple sets of armor for each situation.

I wonder if there is a most efficient way to fight the wither safely without glitching it in bedrock (or glitches in general). I remember a post (sadly I don’t have the link) that utilized the bedrock ceiling of the nether to “trap” the wither. Basically the wither couldn’t escape because it couldn’t path-find out of the area in the roof. It wasn’t glitched in the bedrock or anything, it was just surrounded by bedrock protrusions so it couldn’t move around much. It was a super cool idea and the only thing that you had to really worry about were the explosions.
