In the 'Demon' tab, if I change one of the demon's affixes, is it going to change the demon's HP (the demon was originally captured in 8-player difficulty)?
Don't know this, I don't see why. The difficulty is just kept as-is
Hi, the demon's life is irrelevant regardless if caught on p1 or p8
What matters is monster level and type of the game ladder and singleplayer have higher minster life by approximately 15% more than on non ladder.
Non terrorized monsters have fixed monster level though a terrorized monster will only keep it's level till nexr game. Next game mlvl gets equaled with player level, as to monster life forks chceck maxroll d2 planner and choose a given monster type set the realm, terrorization and monster level.
All monsters except hephasto are correct. Hephasto has a bug and his hp is 2x the actual value.
