This works better, though I would go so far as to simply change the wording for the personal story to this:
Pass: Place a Clue token on this card every time Eunice seals a gate. If there are (insert number of Clue tokens here) on this card, place 'Pass' in play.
Alternatively, you could go with:
Pass: If Eunice currently has at least X Number of Gate Trophies, place Pass into play.
Fail: If there are 8 Doom tokens on the Doom track, place 'Fail' in play.
It holds the same effect, you could increase the number of trophies needed without making it too difficult (since spending takes a LOT of time) and you can keep everything else the same.
