Paladin emblems - Justice or Guardian Falcon?

[AngelOfDark666]

Wilbur has normal def down, Falcon has elemental def down, so they stack. No question my damage on green titans is the highest

Do Elemental Defense Debuffs and Regular Defense Debuffs Stack? Why use them together? For instance, Grimm, Tiburtus, Gormek, Buddy or Wilbur with Guardian Jackal, Falcon, Panther, Arthur, Frida, Nordri, or Evelyn. [MASTER]

Can one use both elemental defense reduction along with another normal defense reduction? Isarnia + guardián halcon
