Snake's Eyes

Whenever you roll multiple dice of 6 faces or higher you may pair the 1's you've rolled, and treat each pair as a single die at its highest value instead.

• e.g. Rolling 5d6 and getting (1, 4, 1, 1, 3) would become: (6, 4, 1, 3) for a total of 14 instead of 10.
• Rolling 1d20 with either advantage or disadvantage (2d20): The result of the rolls as (1, 1) is overridden as 20.
• Dice with different number of faces cannot be paired together.
