Sand Witches

A sand witch would be made of sand and throw sand balls at you witch suffocate you. Did you see what I did there when I said witch rather than which??? 

In Minecraft Dungeons, there would be normal sand witches and mini-boss versions. Mini-boss versions have special attacks (Like Redstone golem, Drowned necromancer etc.). Special attacks include: Sand ray (Turns players who walk into to sand temporarily), Sand summon (Summons sand versions of mobs like skeletons and zombies), Sand duplicate (Like Illusioners they would duplicate themselves). 

When players are turned to sand they will lose health and be stunned. After a few seconds the sand crumbles off their body. This would be the same animation for when sand mobs die (Sand mobs being sand zombies, sand witches, sand creepers etc.). This is also opportunity for new artefacts-  A sand laser (An artefact like the Eye of The Guardian, corrupted pumpkin and corrupted beacon but with a better name; I'm not good at making names) and the Sand wand (Like the Iceologer's ice magic can be used through an ice wand, the witches sand wouldn't be any different. Perhaps a better name is needed here too).

This Sand witch could be combined with other posts and put into an appropriate mission. These witches wouldn't feel correct in vanilla, maybe just Dungeons. I'm not sure. I hope you like this!   :D
