For what it’s worth, I’m grinding 924(!!!) Mourning Candles to set fire to the city – my last chance before the challenge outstrips my Watchful ability (and the odds are still a bit too dicey for comfort, I unfortunately vacillated too much on this decision). Affair of the Box carousel, getting a Revolutionaries Connected pet, and burning opportunity cards for Favours has been working well so far. ~2 weeks of grinding and 700 candles down… getting there… Now what I would love is a Rare Mood card to pop up…
Good luck with the resource grind. The Searing Enigma option is well beyond my reach, so I salute you for pursuing that one.
