The Belladonna Weapons, or Valentine T9 Weapons, are reskins of the tier 9 weapons themed on Valentine’s Day and Belladonna’s Garden.
These were brought into the game in Release 19.2 (Feb 2014) and were available as loot drops from the chest which spawns after Belladonna is defeated. They are now dropped directly from Belladonna herself after the removal of her chest.
These items are not soulbound and can be traded.
