MORE ILLAGERS

We need a lot of evil guys. I think of some kind of boss mob that spawns in a rare variant of Woodland Mansion, with a graveyard. You can summon it by using the Ominous Banner and placing it above its door. Then, it (the Necromancager or something like that) comes, riding a Skeleton Ravager. It can summon three fallen Illagers of its own choice to aid it in battle. When they're dead and its health is reduced by 75 percent, it gets stronger and shoots something like the wither skulls, but less powerful.
