I hope this isn’t one of those “you’re an idiot, it’s supposed to work that way” threads.
But I think there’s a bug when Jabberwock hits the lone remaining enemy and Panther’s Elemental defense down is active on that lone enemy. Both of Jabberwock’s hits should be about the same value. However, it looks like sometimes the Elemental defense down is ignored on one of the hits and the damage is much lower for one of the two hits.
E.g. you should not see hits like this:
Test cases showing normal Jabberwock hits of approximately equal values:
Jabberwock +ATT vs. Isarnia
Jabberwock +ATT vs. Gullinbursti
Test cases showing the bug with -EleDEF:
Jabberwock vs. Leonidas -EleDEF
Jabberwock +ATT vs. Uraeus -EleDEF -Mana
Jabberwock +ATT vs. Marie Therese -Mana -EleDEF
Jabberwock +ATT vs. Magni -Mana -EleDEF
While this seems to be reproducible most of the time. I have seen cases where -EleDef is active and both hits show correct values:
Jabberwock vs. Mob
Jabberwock +ATT vs. Zimkitha -EleDEF -Mana (Non-Raid)
Jabberwock +ATT vs. Domitia -EleDEF
So it’s not 100% reproducible. But I hope this is enough data to point the devs in the right direction to fix the bug. This is using v39.0.1 Build 1545 on Android.
