I have been trying out armor with enchant to see the defences. I read on wiki about Minecraft Bedrock Edition Armour, as you can see that its says one armor bar is 4% damage reduction and +1% per protection level. So I spawned in a Vindicator and it did 9.5 heart of damage. I then wore full enchanted (Protection 4) lether armor. Now, I did the Maths, full leather armor has 7 armor bar which mean 7×4 = 28% damage reduction, as it was protection 4, so 4x4 =16%, 28%+16% = 44% damage reduction. The Vindicator should deal 9.5 - 44% = 5.32, I was expecting to take 5 hearts of damage from the Vindicator, but was surprised to see that I only took 1 heart of damage. Now I don't know why it did that, Is the enchantment broken? Or if it ment to be like that then I would like to say that the Protection 4 is too overpowered, and should be fixed.
