Costume Guide – Blood Glutton Justia (rework)

Potential upgrades

  • +20% skill damage
  • +20% skill damage
  • AOE upgrade (3x3 AOE)

Official Patch notes


  • High fixed damage against dark types in a 5-tile AOE (3x3 AOE with potential upgrade)
  • Low SP cost of 2 SP.
  • Very good in PVE for clearing mobs (the only 3x3 AOE light costume).
  • Very good in PVP at +5 full potential.
  • Long lasting property damage buff, which greatly enhances the power of Justia's other costumes against Dark types.


  • A lot of investment required to unlock its full power: huge damage difference between +0 and +5.
  • Difficult to deal lethal damage in PVP without +5 full potential and high offensive gears.
  • In PVP, not the best light damage even with buffs against dark types.
  • Very long cooldown of 7 turns.

Deep dive on damage

Let's take a look at how the new Blood Glutton Justia performs in terms of damage.

Damage scaling from +0 to +5

A moderately geared Justia with potential bonded stats can easily reach 2500 ATK (though there is obviously room for higher damage with maxed gears). Base property damage against dark types is 50%, and BG Justia's property damage buff is added on top of her base property damage (not multiplied).

Base property damage (Light DMG) is 50%

Therefore, ignoring chains, a 2000 ATK BG.Justia at +0 deals 2500 x 150% x 250% = 9,375 fixed damage against dark types.

On the other hand, 2500 ATK BG.Justia at +5 full potential deals 2500 x 340% x 450% = 38,250 fixed damage against dark types.

You can see that there is a huge damage difference between +0 and +5 full potential. At lower costume levels, BG.Justia feels very weak. You really need to invest a lot in BG.Justia to make her reach high fixed damage.

Justia for PVE

Since fixed damage cannot crit, fixed damage type units like Justia and Alec are inherently disadvantaged in most PVE modes. Except against bosses with very high resistance, BG Justia's damage potential is not all that impressive, even against dark enemies.

A BG.Justia at +5 full potential with 2500 ATK deals 2500 x 550% x 340% = 46,750 fixed damage against dark types. This is not very strong, but the property damage buff carries over to the next two turns. On the next turn, KC.Justia can deal 2500 x 550% x 230% x 3 hits x 110% (for chain damage) = 104,363 fixed damage against dark types.

Compare Justia with Pool Party Angelica +5 full potential. Assuming Angelica has 700% crit dmg, with crit on all 3 hits against a strong enemy (20,000HP or more), Pool Party Angelica would deal 229,680 magic damage against dark types.

Compare also with Comeback Idol Yuri +5 full potential. Assuming Yuri has 1500 ATK and 700% crit damage (including skill crit damage boost), Yuri would deal 140,400 physical damage against dark types. However, if she is first boosted by Whitebolt Yuri, her ATK is doubled.

Note that the difference in damage between Justia and other light units grows even further when AOTU.Diana is used. This is because property damage buffs stack additively. AOTU.Diana at +5 full potential adds +220% property damage, therefore:

  • For BG.Justia, going from a 550% property damage multiplier to 770% represents 40% increase in damage by adding Diana.
  • For Angelica and Yuri, going from 150% property damage to 370% property damage represents a 147% increase in damage by adding Diana.

As you can see, when it comes to maximizing PVE damage against dark types, BG.Justia is far from being the strongest light attacker. Still, she is very useful because she is the only light unit that deals 3x3 AOE damage. Her fixed damage is also helpful against enemies with high DEF or M.RES.

Justia for PVP

Justia is already a very effective character for PVP thanks to her fixed damage skills. Blood Glutton gives Justia the power to now deal wide AOE damage.

A BG.Justia +5 full potential with 2500 ATK does 8,500 fixed damage against non-dark enemies. This is enough to kill most low HP enemies, but not tanks and units geared for HP. What's more, BG.Justia deals damage in a 3x3 AOE for only 2 SP, which is outstanding value.

Note however that BG.Justia at lower costume levels is significantly worse (see calculations above), so low costume levels of BG.Justia are not recommended for PVP. E.g. at +1 no potential, BG.Justia deals only 3,750 fixed damage, which would usually not be enough to deal lethal damage.


The devs reworked BG.Justia because the old version was not seeing enough play. The new Blood Glutton is certainly an upgrade, trading her old defensive buffs (which were not very useful) for new offensive buffs and lower SP cost.

Blood Glutton is now a great choice in PVP if you have high costume levels, but it takes a lot of investment for her to become useful. In PVE, Blood Glutton now makes Justia a better choice, but without the ability to crit, it is unlikely that Justia will ever be the best choice for PVE bosses except in some pretty niche circumstances.
