– Isotope-8 for Heroes (Players Below Lvl 125) –

“Strong Iso-8” means, the name of the Iso-8 and the color it belongs.
In order to purchase this Iso-8 item, you need to go to the [Store] > [Resources] section. Look for the color it belongs and find the specific name mentioned.
Choose the highest “Strong Iso-8” tier you have unlocked. You can get better “Strong Iso-8” item tiers by researching as you progress through the game.
– Mix: means (4:4), (3:4) or (4:3). For 3 Iso-8, Mix means (3:3:2)
– Reactive (Tier 5 and above) Isotope-8: Available for players level 125 and
– Players under Lvl 125 can also refer to the Suggested Iso-8 link above for more options.
– Hero ISO builds may change after a critical Hero buff or nerf! Thanks for understanding. ^^
– Builds: Most builds here are PVE based, but will still work fine for PVP.
– PVP Switching: For full PVP players, I suggest that you just remove or replace Health or Stamina (due to armory bonuses) stats below with Defense or Evasion only. Example: Steady Iso-8 can be switched to Violent Iso-8 (removed Health), Steady Iso-8 to Forceful Iso-8 (replaced Health with Defense), or Steady Iso-8 to Mercurial Iso-8 (replaced Health with Evasion).
– Do not switch Steady Iso-8 to 4 Strong Iso-8 and 4 Precise Iso-8!, it’s lower!
– For Mixed builds, if there are only 2 stats remaining, combine them. Example: Mix
Durable Iso-8 (remaining stat: Defense) and Powerful Iso-8 (remaining stat: Attack) = Full Bulky Iso-8 (Attack and Defense).
– Note: Health stat is still good for heroes that benefits from a shield, shields are health based.
