Delta is a unique fiend who identifies as an automaton. She is the pinnacle of bioengineering, embodying both the traits of the Scientific Inheritance and fiend in one body. Her codename, Delta, and the core installed in her body are legacies inherited from her prototype. After awakening from a deep slumber, she finds herself restricted and under the supervision of an add-on. However...with Master's help, Delta will surely become an extraordinary automaton.

Skill up rule of thumb:

  • Level 2 for Weakness Gauge damage
  • Effect chance, effect duration & cooldown reductions.
  • Damage increases (DPS only)

Chain passive can be left at level 2 until much later, the Weakness Gauge damage increase at level 5 is the only interesting part, so you can save skill manuals here until the more important skills are taken care of.

Damage is actually powerful, and unique skillset that's useful, but the problem is there isn't much stage to actually use Delta in her potential

A passive hero. Hero with a counterattack playstyle specialize in absorbing enemy aggression and immediately punishing them, utilizing defensive abilities to turn incoming damage into offensive opportunities. Huge rack tho.

A Bruiser DPS type with Counter mechanic, deals damage based on her HP stat instead of attack stat. Required specific substat and hard to built early on, not recommended for anyone that just started out. But with correct build and stats, she can deals quite significant amount of damage.

Hard to get damage from her, still has a nice kit and isn't squishy like most dps though her use is limited in stages
