Curse name: Hand of Fate
Amount of turns: 10 + x
Rarity: Uncommon
Cast on: Player or self
Curse effect:
Effects are random. Lose/win gold or fame, increase/decrease danger of a random fleet. More turns invested makes the effect more powerful. 30 turns invested would win/lose 100.000 gold or win/lose 25.000 fame, increase/decrease danger by 15 for a random fleet.
So, you could cast it on yourself, hoping for 100k gold, but get instead 15 danger for a trader fleet, or cast it on an enemy trying to endanger one of his fleets, only to gift him with 100k gold. (The gold comes from thin air, like the Buried Treasure card.)
