Credits allow a character to purchase advantages. There are two types of credits: account credits and character credits. Players can receive account credits by direct purchase through PayPal and by referring others with a promo code. Characters receive 20 character credits when they first use 50 Action Points. Normal Characters have a chance to receive character credits by killing bosses.
Account credits can be used for any character. Character credits can only be used for the specific character that earned them. When purchasing advantages, character credits are spent before account credits.
