Level Up

Leveling up a card increases attack and health by 15% of the card's base values. The cost of leveling up depends on rarity and current level. All cards start at level 1.

Gold cost
Gold cost increases with each level according to the following table, but you can also study the level up table for each rarity by visiting the desired card page in this wiki.

Level 1 to level 50, total gold required to level up only one card.

Normal Cards
Leveling up a card also costs a certain amount of items.
 * Elixir (depends on element). Earth Elixir for earth cards / Water Elixir for water cards / Fire Elixir for fire cards / Dark Elixir for dark cards / Light Elixir for light cards.
 * Necklace (depends on rarity). Common Necklace for most girl cards / Rare Necklace lace (i.e. Dark Queen, Dark Angel, Arabian Princess, Leprechaun, Snow Queen) / Epic Necklace (i.e. Vampire, Elemental Hunter) / Legendary Necklace (i.e. Undead Queen).
 * Misc (e.g. Wisdom Book / Precious Ring / Fairy Flowers / Nature Crown / Luxurious Diadem)
