Iso-8 Crystals

Iso-8 Crystals are used for increasing a heroes' stats and gaining additional passives to turn the tide in combat. They are gained by either being dropped by enemies in combat, rewarded from tasks or by being won from power cells or roulettes. Iso-8 Crystals can come in many different sizes, colours and types with a star rating. They are currently the only type of item in the game which can be sold for silver.


Iso-8 Crystals can come in different sizes. The bigger the crystal, the higher the stat boost.

  • Sliver : +68 to Primary Stat
  • Chip : +125 to Primary Stat
  • Fragment : +208 to Primary Stat
  • Shard : +331 to Primary Stat


Iso-8 Crystals come in different colours. If an Iso-8 Crystal is equiped in an Iso-8 slot which is the same respective colour, it provides a bigger stat boost. The colour of the Iso-8 also determines what stat it specialises in.

  • Prismatic (All Stats)
  • Red (Attack)
  • Blue (Defense)
  • Green (Health)
  • Purple (Evasion)
  • Yellow (Accuracy)
  • Silver (Speed)


Star levels indicate how many stat types are increased. 

  • 1 star - 1 stat (Primary, based on colour) 
  • 2 star - Primary + 1 random stat at a lesser value
  • 3 star - Primary + 2 random stats at a lesser value
  • 4 star - Primary + 3 random stats at a lesser value
  • 5 star - Primary + 4 random stats at a lesser value

There is no discernible pattern to which secondary stats are attached to which crystal.


Each crystal contributes to an Iso-8 set which provides a passive for the hero if enough of the type of Iso-8 is equiped. There are 16 distinct crystal types.

Slot Matching[]

Match the slot colour to gain extra stat boost.
Stat boost is an extra half of normal stat increase.
eg: a crystal that adds +208 to attack, when colour matched to a red slot, grants an additional +104 attack.
Odd numbers are rounded down eg : +27 stat gains a +13 Bonus.


  • Passives gained by Iso-8 Crystals are only count once. (i.e. if you slot 4 Rejuvenating Iso-8 Crystals on one hero, it will count as 4/2 Rejuvenation)
