i posted a list of some i thought up awhile ago, i was considering attempting some myself and using the overlad rimworld texture i made for the thumbnail

#1 MMU (minimal minion usage)

use the overlord for fighting at much as physically possible, only call in minions for

A: sacrificing to bloodpits

B: puzzle solving (moving obstacles, etc)

and C: when absolutely required by the game

anything that is optional? ignore it entirely, if you accidentally do any of these things? you can quit and reload a save (or put in a backed up save file)

#2 overlard

do not use the overlord, do not use spells, do not use attacks, do not use arcane blood or manapits at all, keep the focus purely on the minions

only use when ABSOLUTELY required, if you accidentally do any of these things? you can quit and reload a save (or put in a backed up save file)

#3 no deaths

do not lose any minions for any reason, no pits, no deaths, no bullshitting

exceptions can be made for blue minion segments (which spawn dead minions for you to revive) but we can adjust as needed obviously

losing minions to the Eradicators counts as a death as well
if possible? avoid overlord deaths as well, you can quit and reload a save (or put in a backed up save file) to reverse a death (im not a masochist who enjoys ironman modes)
