Shakingchills

The Shakingchills would be a new type of hostile mob that could be found in the End.

These would be relatively difficult to find.

Mechanics:

• They would not have much life, about 20 hearts of health in normal mode.
• They would detect the player within a radius of up to 32 blocks.
• They would be partially invisible, since their eyes would be seen and when hitting them they could be better appreciated for 7s.
• They would have the ability to fly, as well as a ghast.
• His attacks would be a melee with a damage in normal mode of up to 6 hearts and up to a maximum of 8 hearts at the time of having 65% less health.
• This mob could be affected by potions of damage and poison. Invisibility potions would give him Strength 1.
• He would make chill-worthy sounds and believe me you're lucky not to see his entire appearance, thanks to his invisibility, of course.
• Upon death, the mob would drop some chains, from 0 to 3 with a probability of 33% each.
• 1 obsidian with a 50% chance.
• And with a 10% chance of dropping a "fang," it could be applied to an underworld tool, weapon, or armor without enchanting on an anvil (without changing the appearance of the tool, weapon, or armor itself) and thus be able to increase the chances of a better enchantment being played.

In my opinion, this mob could be included in the game at any time, although it would not be wrong to put it in a hypothetical "End update", since with the set of various ideas from the community, like this one, something like this could be achieved.
