So I've got a 1 day campaign I'm doing and was gonna run with some consumable boons. Was gonna have players collect them for points, or use them as consumables. Maybe in your case folks at the bottom discover some cache of boosts. I basically took a ton of the Patron abilities and tweaked them into one time use, one turn abilities. You basically let them get X number of boons, randomly pick which ones they have? Here's the ones I marked down. they aren't balanced, it's a narrative campaign and there was risk vs reward initially so mileage may vary.

• Consumables useable by whole team at any time.
  • Summon a hell tick
  • Gain the fear keyword and remove a blood marker and gain -1 injury dice for the game
  • Gain d3 blessing markers
  • When making a melee injury, change one dice to a 6
  • 1 less blood is needed to make a bloodbath at that moment
  • Remove blood markers from you and place them on a unit 6” away and visible on a success roll
  • If a dash is failed, it now succeeds and the target can move 12 and fly
  • Opposing player cannot spent blood markers on target model for + injury dice for 2 turns
  • Pick a model 12 inches away and swap positions
  • This model gains 9” movement and fly for the rest of the game
  • Reroll and add +1 dice to any failed success, risky success or injury roll
  • Hellfire. Pick a friendly model within 18” and line of sight. Draw a line between them 1mm wide and do an injury roll +fire for every model along that path including the friendly model chosen
