how do you get potions of cure corruption? picked up ether disease early. they are not in shops. i take it they are rare.
As Niveras said, gambling. It's best to not to use a casino item (dartboards, card tables, slot machines; you can find them in Derphy and Palmia easily) until you get a lucky dream. You have a chance to get one at 4 wins, and get one guaranteed at 5.
Other less reliable ways include finding them on the ground in dungeons, in your salary (VERY rarely IIRC), in shops (you'll have to pour a lot of gold in like he said, and they cost around 150k each), and from marrying your pets. Which leads to the next point.
i see a post about relationships and pets. how do you get them to like you better? anyway to see their stats or what level they are?
The cheapest way is to let them kill things for you. You'll know when they gain a relationship point when you see a heart over their head. You can also use love potions, but don't give it to them directly as it'll cause karma loss and a relationship drop. Instead, mix it with food and give the food to them (still karma loss) or throwing it at them (not sure if it works personally but no karma loss).
The only way to see their stats/level is to pay the informer. You could also use the gene engineering machine, as it shows the character sheet of the result if you mash two pets together.
sometimes npcs have symbols over their head. its obvious which one is sleep. is there anything in the help about the rest of them?
I don't believe it says it in the help, but
they're here. I believe it's also missing the little angry mark which you can probably guess the meaning of.
