[DFFOO JP]Prompto 90/90 reduction w/Llyud as buffer and EX recharger
This is a more tamed setup with Llyud pretty much the sole buffer besides Prompto. Other than 50% BRV dmg up, and 30% HP dmg up, Noel does not provide too much for boosting Prompto's damage.
Needless to say, with a tanky (not HP-wise in this day an age) boss with 90/90 reduction, all 3 calls are used for debuffing purposes. Noel's BRV cap increase did not help Prompto much without hitting pass the normal cap by a large margin (around 13K most of the time), so in hindsight, maybe Garland would work better with the additional 50% BRV damage up.
That said, however, to put it into perspective, his follow-up actually hits harder than Noel's follow-up. His EX can still hit the 10K margin despite a rather minimalistic buff aura setup (remember Llyud's 80% dmg up is not for party, he only has party-wise 40% brv dmg up and a lot of ATK up). So spamming a consistent amount of 500K EX on each target was still annihilated them in no time.
Also, crackshot++ ignoring defence was really good here. It almost is a guaranteed capped damage attack. I did goof once and use LD instead of Overkill++ to just instant break the target when they both have 60K+ BRV gain though, so that was a misplay there.
In terms of battery, even with 90% reduction with practically no BRV gain up aura, he is now giving around 15K to every one. His battery in this stage used to be largely negligible, so it is a significant improvement as well.
Suffice to say he is much easier to slot in a party than before now and can be a staple well-rounded support.
Also attached a clip of extreme BRV cap increase with Garland and Noel besides Prompto @11:20 just for fun. I probably can put them in Queen's Lufenia+ and still work, but that was actually my first test and I wanted to see what silly things can happen when you dump all kinds of CAs along with the ride. Honestly Prompto probably needed HP cap increase more than those CAs in that situation.
