For the red haired girl who lets you sleep in her house, can you make it so that she drains HP (you recover at 2/3 HP and -1 level or -2 levels? It says you have a strange dream and you feel that you got drained but the status doesn't change).
Hoping for negative status item that drops your resistance and turns 'Sleep into Deep Sleep for 15 turns' for 66666 gold. Or you can button mash to wake up or stay asleep for as long as you want (but if you have Amulet of Nightmare you'll just deep sleep for just 1 turn)
There's a bug where if you defeat Linda? the red haired succubus, you can go to the bed, get drained and get your levels back.
