^^ Maybe something less cliche as a big skull might be lady luck herself casting the dice, or some strands of hair on the skull to suggest it’s lady luck.
^^ Also “Warriors by Fluke” is much funnier but I haven’t the heart to change it.
Tiz similar to RusBear’s suggestion, had another idea but monks praying to gold might not be cool enough for people to use :D
