This is my idea for something called trim enhancements

Minecraft trim enhancements Each dimension/terrain such as The Ocean The Nether and The End would have a special enhancement/enchantment that would be found in the main structure found in that dimension/terrain so The Nether would be the Fortress The End would be the End city and The Ocean would be the Ocean monument each would add a special effect to avoid the danger in the dimension/terrain so if you have a Nether enhancement trim on 1 of your pieces of armor piglens wouldn't attack you unless you attack first if you have 2 trims you would take less fire/lava damage and every piece of trim after that makes you take less damage and on the last one you get full fire protection and for The End you would get the slow falling a effect but still take less and less damage until you have the full set which would make take no fall damage and for The Ocean longer time breathing under water (stacks with respiration) and dolphins grace and the time gets longer and longer until you have the full set which would give you water breathing they would be harder to duplicate then regular trims so The Nether enhancement trim would take 7 diamonds and wither skull The End would need 7 diamonds and a dragon head finally The Ocean would need 7 diamonds and a sponge and you could at the enhancements to and trim the add it on you armor
