These have all been addressed already, either with game mechanics or dialogue.
- Knowing when an adventure is wearing a Bra of Holding is pretty simple. Flat chest = Bra of Holding. To loosely quote a bit of in game dialogue, “I’ve never seen a woman in the area with anything less than a G cup.”
- The Rogue multi class is only true when the main color of an outfit is black or grey. You may also be missing a butt potion if the adventurer has a climbing item (rope, grappling hook, crossbow with claw arrow, whip), which requires a thigh potion. If you add a thigh potion, you need to also add a butt potion if it doesn’t contradict other rules. (e.g. adventurer with whip fighting skeleton= Thighs but no butt)
- You can view the rules by right clicking on a potion/item to see details. You can also press and hold if you’re using a touch screen.
Hope this helps! If you’re still having trouble, use the walkthrough.
