Sparks are used to rank up your bot, to increase your bot's potential by increasing the bot's level cap. Ranking up a bot sometimes can unlock new special abilities as well. There are 4 tiers of sparks. Each tier is used to rank a certain level of bot dependent on it is a 1-Star, 2-Star, 3-Star, or 4-Star.
There are different kinds of sparks:
Basic Spark: Found in the raid store.
Class Spark: Found in daily missions.
Alpha Spark: Tier 1 (Used in the ranking up of 3 and 4-Star bots) Essence can be found in the raid store.
Sparks need to be in your inventory to rank your bot up. If a spark is located in your it will not count for the upgrade. You can also collect spark essence and exchange them for sparks in your inventory.
Where Can I Get Spark Essence?
Essence can be obtained from the raid store, daily missions, event rewards, and from selling sparks.
How Much Essence Will I Need to Construct A Spark?
This will depend on the tier of spark. The amount of essence needed will be displayed in the inventory menu for each individual spark and may vary depending on the tier.
Why Didn’t I Get Essence From My Tier-2 and Tier-3 Basic/Class Spark?
Essence can be obtained from tier 1 sparks. Keep in mind that Tier-2 and Tier-3 Basic Sparks, as well as Tier-2 and Tier-3 Class Sparks do not provide essence when sold.
How Do I Use It to Rank Up My Bot?
Once you have maxed out a bot’s level within a rank, you will be able to rank up your bot. The requirements for each upgrade depend on the current rank and tier of your bot.
To upgrade the rank of your bot, open the bots panel in your main menu and choose a maxed out bot to upgrade. Select the ‘Upgrade’ option and tap on ‘Rank Up’. Remember that you need to have enough gold in your inventory.
