About Tesla Storms

Tesla Storms are a battle feature where you face Tesla directly in his mechanical robot. Defeat Tesla within the time limit to receive ascension materials, which are used to ascend your heroes.

You can access Tesla Storms through theBattle menu in your main city.


There are five Tesla Storm colors, matching the five elemental hero colors: blue, green, red, yellow, and purple. Each color limits which heroes you can use.

For example, if you want red crests, you need to fight in red Tesla Storms, where only red heroes can be used.


Crests come in several rarities: Common, Enhanced, Superior, and Midnight.

The further your heroes ascend, the rarer the crests they will need. To obtain rarer crests, you will need to clear higher Tesla Storm stages.

You can check your current crest amounts in the Ascension Material menu, accessible directly from the top menu.


Stages 15 and higher also have a chance to reward you with Tesla Cores, rare materials required for higher ascensions.


Battle Against Tesla

Tesla is immune to most negative effects. You cannot Stun, Charm, Ability Block, Mind Control, or Trap him, and you cannot reduce his ATK, DEF, or Accuracy. DoT effects still work against Tesla: Bleed, Burn, and Poison can damage him.

Be careful with abilities that also strengthen their target. For example, Jane Austen cannot make Tesla fight for your side, but her ATK increase can still apply to him, making Tesla stronger against your heroes.

During battle, the counter shown under Tesla’s health slowly fills up. Once the counter is full, Tesla will use one of his special abilities. One of these abilities summons minions, during which Tesla becomes invulnerable.


After the minions appear, a timer will be shown on Tesla’s counter. If you do not defeat the minions before the timer runs out, they will explode and damage your heroes. Once this phase ends, Tesla’s invulnerability is removed and the fight continues.
