A recent discussion in the ‘Unusual Goals’ thread made me wonder about this, and I didn’t want to derail it, so…
Basically, I have a vague, long-term ambition of ‘collecting one of everything’ in the game. A cursory glance, however, makes it clear that I’ll have to attach a footnote to that idea… namely, ‘Except mutually exclusive items’. There are some things, after all, that you can only obtain by giving up on something else. But I wonder… how many are there, really?
Here’s what I can think of, off hand:
The Exclusive Pets: Salt-Weasel, Rubbery Euphonium and Haunted-Looking Dog are mutually exclusive, for no apparent reason. You can only have one of them, at any one time.
The Ambitions: You can only have one Ambition, so any item specifically associated with those ambitions are - by definition - mutually exclusive. Of course, most of them are unsellable and unuseable anyway - what might have been termed ‘Key Items’ in another sort of game…
The Occupations: Each occupation grants you an item of some sort, and you lose the item if you change occupations. So you can only have one out of that dozen-odd items at any one time.
The Seekers of the Nadir: At the end of the Irrigo Cave quest, you have to choose between the Revolutionary Firebrand and the Secular Missionary - gaining one of them as a companion, and losing the other. You can send them both packing, but you can’t KEEP both. By extension, their ‘evolved’ forms - available during the Feast of the Exceptional Rose - are also exclusive.
The Patron’s Gift: You select a Patron near the start of the game, and receive one of four gifts for your troubles: The Brass Knuckles, the Unobtrusive Bowler, the Mint Humbugs or the Mirror-Polish Shoes. You can only have one of them at a time.
The Soul-Trader’s Bounty: The Fate-Locked ‘A Trade in Souls’ storyline grants you a Spirifer’s Fork or a Shepherd’s Timepiece, depending on which side you choose. Only one can be owned at a time.
The Tales or the Stone: The ‘A Disgraceful Spectacle’ opportunity-card (Rare, it seems) lets you collect either a Blue and Shining Stone, or a Headful of Picaresque Tales… and as long as you have one or the other, the card will not reappear.
Those are just the ones I know of, though, and I’m not yet far into the game. Just so I know how many exceptions there might be to the ideal of ‘collecting everything’ - can any of you think of any other such exclusive items?
