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]

To the best of our knowledge, the debuffs stack multiplicatively. Example: You take Grimm (34% general defense reduction) and Jackal (-54% Holy defense reduction). The target’s effective defense is (1 - 0.34)*(1 - 0.54) = 30%, or a 70% defense reduction. Remember that this goes into the damage calculation inside the exponent. The general formula says expected damage is proportional to (Attack / Defense) ^ 1.35. So a 70% reduction in effective defense basically quintuples the per-tile damage. T…
