The lunatic cultist is underrated, it should have more loots like maybe an ancient doom staff or stuff
yes, it’s troublesome to fight him again because of the pillars but I think he deserves to have more drips instead of 1I think the reason he's not really dropping anything is
1.) because he's a huge pain to rematch as defeating him starts the lunar apocalypse, so if you didn't get what you wanted, then good luck trying again.
2.) anything he would drop could easily become obsolate 10-15 minutes later or sooner, as soon as the first pillar is down and you craft a pillar-tier weapon.
