Items

Items are used throughout Marvel Contest of Champions to help the Summoner with various tasks. These items range from different kinds of currency to cosumables for champions.

Currency
So far, there have been 3 types of currency released that the Summoner can use:

Gold
Gold is the most abundant of the three types of currency. It can be obtained through various means, including by completing almost any action in quest mode, albeit in small amounts. These actions include: Gold has one main use in the game: Upgrading and ranking up champions. Along with the necessary Iso-8, an appropriate amount of gold will also be necessary for the upgrade/rank up to take place. This amount is proportional, so the lower the level/rank, the less gold it will cost, while the opposite holds true as well.
 * Moving spaces in quest mode (Aprox. 11 - 14 gold per tile)
 * Defeating an enemy in quest mode (Approx. 112 gold per won battle)
 * Defeating a boss in quest mode
 * Finding and passing over a chunk in quest mode (Variable)
 * Opening Arena Crystals (3000 gold)
 * Opening Versus Crystals
 * Opening Free Crystals(?)
 * Opening Daily Crystals (?)
 * Selling other items (Get item prices)
 * Obtaining duplicate champions (Depends on duplicate tier)
 * Opening a lockbox after defeating 1, 2, or all 3 opponents in a 3v3 Arena (?? gold from 1 star box, ?? gold from 2 star box, ?? gold from 3 star box)

Battle Chips
Battle chips are the second most abundant type of currency in the game, being harder to amass than gold, but at the same time not being too terribly difficult to obtain. Battle chips are mainly obtained in versus mode, the PvP function of the game. The Summoner can obtain them by: Battle chips are mainly used to purchase Arena Crystals, as they cannot be obtained in any other way. Another use for battle chips is the unlocking of certain 3v3 Arenas. Sometimes a new 3v3 Arena will be available, but will first need to be unlocked by paying some amount of battle chips.
 * Defeating an enemy in a 3v3 Arena (10 chips)
 * Opening a lockbox after defeating 1, 2, or all 3 opponents in a 3v3 Arena (100 chips from 1 star box, 200 chips from 2 star box, 300 chips from 3 star box)

Units
Units serve as the premium currency of the game, being the least abundant of the three types and taking signinficant effort and patience to collect. As with most premium content in other games, units
