Packs

Packs, also known as Booster Packs, can be bought with Power Credits or real money in the Store OR can be obtained if completed a certain amount of Battles for a character's Challenge. They can contain either character cards, with or without support cards, along with a possible chance for an Upgrades, and/or Gear cards. For some packs, their contents may be fixed or random; on the other hand, some can be permanent or temporary (i.e. does not always appear in the store).

Obtaining a character who first needs to be unlocked in Challenge Mode or a WBID account (or through the Store) can be promoted DIRECTLY with Power Credits. Otherwise, if obtained from any most Packs, they cannot be promoted directly.

Trivia

 * Previously, the card's stats on the pack's interface are modified by support cards. This has since been removed and now they show their base stats.
 * Most of the non-random temporary packs are around 25% cheaper than the characters are separately. A major exception is the Arkham Asylum Pack, which only saves about 3.6% possibly due to the difficulty of otherwise obtaining Harley Quinn/Arkham.
