Interactions

• Trinket Multipliers / Henge Rock: Affects the base chance for Thunder Egg to hatch, and the quality of the Rock it hatches into.
  • If the total multiplier is 2 or higher, the hatched rock is guaranteed to be of Fiendish rarity. Otherwise, a total multiplier under 2 will have no effect on this chance.
