The Hex illager

The Difficulty of raids are quite low you just pillar a tower and use your bow, Besides Vexes the mobs are easy to outsmart. To help increase raid difficulty I propose the Hex Illager, This mob could use a invisible barrier to keep and one in a ten block radius of it immune to long range attacks and itself as well. One other thing it could do is cause status effects for any one hit by its weapon ,which is still undetermined, the status effects would be either blindness ,weakness , poison , or mining fatigue
