If you could get lucky enough to acquire an Asylum via Hyborem's Whisper or Diplomacy, and the civ that summoned the Infernals had already researched Mind Stapling, Hyborem can get the same sort of ridiculous benefit from lunatics that Basium does. Hyborem can't build an Asylum, or conquer one for that matter, though, so it takes some luck.
Although, played as Hyborem, my selected city HAD asylm, it dissapeared after changing ownership via hyborem's whisper.
Tested hyoborems whisper several times. Sometimes you get selected city with asylm, sometimes not.
I cannot upgrade captured slaves to lunatics as hyborem, although all requirements are met
I got it: you still have to switch to OO and research mind stapling first ( your "mother civilization" already did it but it does not count)
But its better DOW on barbarians or be at war with others, there simply is not enough animals for lunatic suicide.
Directly built lunatics for hyborem are demon race - no manes. Only slave upgrades work.
Lots of micromanagement - pick up captured slaves from the field, airlift slaves to your previously lanun owned city, upgrade, usually lift again ( one per turn), release.
Now...where are my manes ???? At least aganist of barbs ..none...( showed middle finger to them)
My own lunatics dying - no manes, other lunatics dead=manes
also under OO hyborem can build asylms.
My guess: only enraged "your" lunatics dying count as manes ??? ah, screw it.
