New enchantment: magic invulnerability

Magic invulnerability would go up to level 4 and be compatible with all other protection enchantments. It would reduce the length of and how much damage is done from harmful status effects depending on the level. However, it cannot be found on enchantment tables and only be found by a very lucky fishing trip, villager trades, and certain loot tables (like a witch hut chest loot table). This is a very useful enchantment in certain places like: nether fortress, ocean monument, raids, and the wither fight. Milk still has a use, though, as it stops all status effects (good and bad) but doesn’t keep you safe as mobs hit more times than just once. One reason that I really want this enchantment is because in bedrock edition, the wither is so overpowered. This is because is has double the health than on java edition, the wither status effect kills you, and it has special attacks.
