Would this include summoning eyes? My guess is no because summoning eyes are technically a 100% drop chance from a rare mob, but I want to know just for clarification. If this is the case, would it be possible to add it to the "rare loot" pool?
Negative, although they DID remove end portal frame zealots from the game, the zealots that hold summoning eyes have a higher defense then regular zealots (they all have the same amount of health to prevent sniping).
Thorns is not "fixed". I put on a full Thorns III set and let an endermen hammer on me in a corner and I still couldn't damage the mob 99% of the time. This enchant is still trash tier tier and makes your DPS lower and your loot less plentiful.
I'm not sure if this bug fix caused it but now the magic water bucket is kind of disappointing. I can't use it to make rows of water infinite because it won't place on flowing water. I understand fixing it so it won't replace blocks but make it able to change flowing into source again. The sound of running water is annoying and unsatisfying.
