1.17 Mountain raiders

With 1.17 coming and the snow falling I thought of a new Illager the mountain raider! These mobs would attack mountain villagers that sport fur coats (and a new profession: the lumberjack!) They carry crossbows with freeze arrows which give you the same effect as sinking into powder snow. They will take damage in hot biomes as they are wrapped up warm however they can take their coats of and become pillagers. They would drop their arrows and goat horns which they blow. when near a village and it starts a raid. There are multiple versions of the mountain raiders including illusioners! Who wear purple robes and carry iron swords instead of bows, if you wish to summon the original just type: 

                                                    /summon illusioner~~~{IllusionerType:1}    

When the duplicates appear a crystal on the originals belt glows kill them to get it: the pulsing amethyst which you can brew with a thick potion into an illusion potion that summons fake and real zombies to attack the drinker it also gives nausea. The mobs can be modified by adding a drop from a specific one e.g., crossbow = pillager rotten flesh = next undead after zombie: husk 

These mobs are very dangerous so watch out when exploring mountains now!
