The Duvalia has been revealed as an Infected card in the Resident Evil: The Deck Building Game expansion, Alliance. The Duvalia has an interesting effect; if it defeats a player, the player with the most decorations is given five "ammo x10" cards. This effect is meant to put the player in the lead at a slight disadvantage by giving them cards with minimal amounts of gold and ammo.
The Duvalia has 60 health, the same as Nemesis T-Type (MA-007) from the base set, and can deal 40 damage if the player does not defeat it. On the other hand, it gives 5 Decorations to the player who defeats it.
