While I hate the diabolist to death, I don't think removing it would be the solution, instead a nerf would fix them (along with ragged casters and necromancers) by either making them dealRemove all block piercing enemy projectiles from the Dungeon.
No one likes these, they add nothing to balance, they just ramp the difficulty up to obscene levels for absolutely no reason. You have ZERO options to deal with any of this until hardmode, it baffles me to think anyone thought this was a good idea.
Tight corridors, traps everywhere, an almost endless river of enemies, false walls you have to slowly dig through, and ON TOP of all that an enemy that shoots projectiles through walls and teleports all over the place.
The ONLY options to deal with these kinds of enemies are the Death Sickle, Solar Eruption, or Zenith. If you are NOT melee and are NOT in hardmode, you have ZERO options for dealing with them besides hoping they teleport somewhere you can get to quickly.
Let me repeat that, if you are NOT melee, you will NEVER have an option to deal with them.
And then eventually they add three new types of this enemy that can either A) Kill you instantly or B) Blind you.
Making this plea for mercy with whatever development power you have because I'm currently trying to get a single item from the dungeon, you always forget how bad it is after a while of not being in there, then when you're pre-hardmode and it's time to go get some dungeon loot you remember what an absolute frustrating mess the dungeon is.
less damage, give them a longer cooldown before firing or even outright making them not teleport the moment you hit them.
