Edited message at bottom.So this has given me (I think) an impossible puzzle. Thief fighting skeleton, throwable weapon. no butt potion. No melee weapon, so no chest potion. they have breasts, so no milk potion. no Gems. cant use jiggle potion cause there's nothing to jiggle. This is...I dont know what to do to progress. Think this is an oversight.
So it turns out, despite having no melee weapon I can actually use the milk and boob potion because she's fighting skeletons. Not a bug. just my ignorance.
