rubies and miner skeletons

The ruby ​​could be a good mineral for the game but that they have another function such as that it works as a trade item but with another mob like a mining skeleton that has the same artificial intelligence of a piglin but instead of having armor you must necessarily bring a mining helmet so that it does not attack you and that it can be traded with rubies this mob would spawn in the dripstone cave the ruby ​​would have the same probability of the iron but the same amount of the emerald in the dripstone caves and in other caves have the probability of the emerald and the amount of iron, the ruby ​​would be above the stalacmites which would do a dangerous job to get it in other caves will not present danger since it will be very difficult to find the ruby ​​in the case of the helmet it can only be achieved if you kill the skeleton. Speaking of the skeleton, it would have a 7.0 porcent probability of spawning (or any other only that is difficult to find), its natural enemy would be the zombie, but if the skeleton comes to the surface even with the helmet, it will burn and leave bone meal when burned to death.
