SGE + SCH: What doesn't stack?

[pinkbubblegum]

My cohealer is an AST, but they used to be a SCH main and I feel quite bad forcing them to go AST if they wanna be SCH so we're gonna try doing stuff with a SGE SCH comp this weekend but I was curious what stuff doesn't stack o:

As far as I know, it's only gcd shields right...? So Succor + E Prognosis or Adlo + E Diagnosis would overwrite? But their ogcd mits work fine together...? Does the mit from Sacred Soil and Kerachole stack as well? Thanks!

Correct, GCD shields don't stack. That's most of it. I believe damage buffs/debuffs from the same job also don't stack; two Chain Strategies won't have any additional effect if applied at the same time. It's also important to note that mitigation is multiplicative, not additive. This means that all mitigation after the first will have diminishing returns if stacked, so blowing all of your defensives on one attack won't just put abilities on cooldown, but they'll also reduce less damage than they normally would if you space them out.

Just adding onto Semi's point, if say, you were to use E.Diagnosis on the tank, and the SCH were to Adlo, it will ALWAYS overwrite, even if the Adlo is smaller, and vice versa. Same for E.Prog and Succor.

But that's it really. Kerachole and Soil will stack, as well as all the other oGCD regens/shields that the two have.

Everything can stack outside of GCD shields.
Eukrasian Prognosis + Eukrasian Diagnosis will overwrite Succor / Adloquium and vice versa. This is because " Galvanize ", " Eukrasian Prognosis " and " Eukrasian Diagnosis " will all overwrite each other.

For the same jobs (ex: 2 sages or 2 scholars), the bigger shield will overwrite each other. Eukrasian Diagnosis will generally overwrite Eukrasian Prognosis only because the potency of Eukrasian Diagnosis is usually higher than Eukrasian Prognosis on a single target. The same thing happens with Succor and Adloquium. However, please keep in mind that is because they are considered the same type of "shield buff" even if they happen to have a different name.

The GCD shields that stack would be Catalyze and Differential Diagnosis (just tested). On crit from both jobs, these shields will remain on the same player even if the base shield gets overwritten.

For oGCD mitigations: Kerachole, Sacred Soil, Fey Illumination, Holos, Panhaima, Haima, Consolation, Krasis, Expedient, and Protraction all can stack together.

On 2 of the same jobs (ex: double SGE), certain buffs will not stack together, such as the double mitigation from Kerachole or Taurochole. This also happens to Physis II's autophysis buff - one will disappear, but the two healing HoTs will remain. Whispering Dawn can be stacked without an issue because it's just a HoT.

Woh, that's super detailed haha. Thanks!!!

I guess you'd also ideally want sage e diagnosis to be prioritized during downtime, for addersting generation.
