Salvage Stockpile is a reward card given to players for completing certain quests. Its purpose is to be salvaged. This card has a rarity of Legendary, so it is worth 40 Salvage Points when salvaged. However, it cannot be upgraded, as it has only 1 level.
Salvage Stockpile can be played as a normal card in battle. This card is an Imperial structure with 1 health and no skills. At present, this card, the rare version, Salvage Crate and the vindicator version, Salvage Warehouse are the only exceptions to the rule that "Structures have at least 1 skill."
