stat scanner item

idea is of item that would show you stats, such as HP, armor value or possibly other relevant stats of mobs or players, such as horse individual stats, if applied, maybe even revealing potion effects could be possible

it could be useful informing accessory for newer players or players who want to test out and compare various things

since coming in form of item that is required to be actively held, it would be not OP or anything, considering how many useful items can be held in secondary hand, such as shield, blocks, bow/crossbow, spear..., so it would give you advantage of information but sacrificing other utility

should work only in fairly close range, about as how is reach with regular melee attacks, maybe slightly further but not like ten blocks or anything, except moment it is used while looking trough spyglass, extending reach of this items stat reading, such would let you use it to check out mobs/players from decent distance, but also not letting you use use any other item at same time, also adding actual item synergy

crafted probably of copper, since that is metal that so far has not "information item" (gold has clock and iron has compass), together with amethyst or echoshards, giving those two items more uses

stats shown by it could show above entity it reads similarly where nametags appear, rather than being part of UI directly
