Elder Guardian Improvements and Eye of the Guardian

Most players consider Elder Guardian as a minor boss or an end-game challenge. But they don't have good enough drops like other end-game challenges, bosses or minor bosses ( Evoker and Wither for example ). So I think there should be a new drop for them, and that is the Eye of the Guardian ( Idea from the weapon of the same name in Minecraft Dungeons Hidden Depths DLC ) which is a weapon that will shoot a continuous beam which deal 2 heart of damage per half second. Elder Guardians have a 1 in 3 chance of dropping one. Eye of the Guardian requires Exp to work ( 1 Exp level per 2 seconds ) to make it not overpowered. It also have a durability and could be enchanted with Mending or Unbreaking ( Or maybe a new damage increasing enchantment exclusive for this weapon ). And also I think Guardians should become Elder Guardians if struck by Lightning because of the fact that Lighting converts mobs into more Corrupted or Powerful versions of them ( Villager, Creeper and Pig for example ). This will make Elder Guardian renewable in an end-game way. If the drop chance of the Eye of the Guardian is too high considering they can be farmed by lighting after this addition, the solution is reducing the drop chance or reducing the chance of Guardian converting to Elder Guardian after getting struck by Lightning.
