Shop talismans

Two items from the shop change the +10 to +15 combination. Put them in the machine with the item; they are spent whether it works or not.

  • Talisman of Luck: +1% for 10 diamonds or +10% for 100. A combination adds up to 10%.
  • Talisman of Chaos Assembly: if the combination fails, the item stays as it was instead of vanishing. One per combination; jewels and zen are spent either way. 150 diamonds.
