Thread: The value of stacking Def DWN (with damage calculator)

I added a general damage calculator to the same tab, which accepts a variety of modifiers including HP, ATK, DEF, and DMG (reduction), and outputs the modified damage and--most importantly--how this affects the hits til death (HTD). This is a stat I came up with that's a bit more intuitive than effective HP, but serves the same purpose. For example, imagine a scenario where you could reduce incoming damage by 90%. 5% more damage reduction on top of that seems paltry, but it actually DOUBLES your survivability.

if i understand correctly, negative value of "ATK up" = atk debuff value, while "DMG modifier" = atk buff on enemy?

DMG modifier is the positive expression of 'damage reduction'. Likewise, ATK up is the positive expression of ATK down. If you want negatives, add a negative sign. I wanted the stats to all be expressed in the same direction for consistency.

Hm, it appears that dmg cut, like 40% from Joan's "Voice of god" is less potent if you have atk debuffs stacked on enemy... Speaking of Joan, how does her Def bonuses apply to this formula? Is that a direct -23% to DMG modifier? +23 to DEF up? (Im trying to figure out who is more potent at keeping your party alive at high dmg bosses, like blue raids? Andromeda with a flat 1600 heal or Joan with all def bonuses, dmg cut and regen...)

Attack down debuffs and damage reduction interact multiplicately--that is, they're equally effective separate or together. So there should be no loss in potency.

Apply defense up buff bonuses to the Defender DEF up box. Assist defensive passives are additive with DEF up buffs (for that character only). Passive soul bonuses to DEF are multiplicative and I haven't factored that into the calculation. Doesn't seem useful overall since most of the time you care about your weakest link, not a single character stacked with damage reduction bonuses.

Also, make sure you're using the latest version of the spreadsheet. I'm continuously revising it, and early on there was an error in the damage reduction calculation that could have resulted in your observation about Voice of God.

Just so we're clear on how these debuffs apply: you can have one def down debuff from kamihime and one def down debuff from eidolon sources, right? And they will overlap? But you can't have multiple eidolon def downs, or multiple kami defense downs?

You can have one eidolon debuff on top of everything else, and eidolon buffs cant stack with each other, but when it comes to kamihime, its not so easy. There are 3 "frames", or "windows" for debuffs, A-frame (usually skill that affect only one stat, like atk down) B-frame (usually skill that affect multiple stats, like atk and def down) and C-frame (rare frame, that is an "exception" and should be memorized, who has this kind of debuffs) A-frame can be stacked with B-frame, and C-frame, but not with another A-frame. B-frame can be stacked with A and C, but not B. So potentially you can have A, B, C and Eidolon debuffs stacked together, but in practice theres a cap on debuffs (50%) so theres no reason to go overboard.
