silverfish potion

so, silverfishes are actually just a way to get XP, what if a drop from them was added so this drop could be used to make potions, and those potions could reveal nearby minerals, this may need to make a different sistem for the silverfishes spawning, but, may be usefull for those people who spends a lot of time getting 1 diamond vein, the potion may only show iron and coal, but if upgraded to glowstone it'll show gold and diamond, this can be nerfed by adding a 4x4 max distance to reveal ores
