So, time to talk shop about a revealed tech that I am extremely excited about. "Joyous Toast"
There is a couple of things to note here. First off, this tech is slow, like really slow. You have to have IPF active already, then you do this which does nothing on the turn that it is activated, and then the next music, dance, or art based technique (presumably next turn) is bumped up a rank for determining effects. Slow, but very powerful, especially when used with higher ranked music, dance, or art based techniques. Lower ranked techniques aren't as valuable for being buffed, however, as the difference between those ranks are smaller compared to say... the difference between B and A (or A and S).
So, what techs does "Joyous Toast" work on? Well, anything from PLR, SCS, FSS, and FVM as those all have dance or music in their categories. Which ones should we use Joyous Toast on? Well, a couple spring to mind. First off, all of these techniques are all going to be the improved versions which we don't have yet, the non-improved versions work as well.
Bumping this up to B means that the qi drained will be more (which means more for us) and there will be more of a debuff when the sights and sounds cloud the target's mind and steals their strength. All in all, a pretty good buff.
This one is actually interesting it should increase the damage by a rank as well as increasing the debuff to the target's vitality and will. This is important, as we have other debuffs that have additional effects when a target fails a save that has something to do with their will. So increasing the debuff to the target's vitality and will could be used to trigger some other debuffs.
Using Joyous Toast on Grinning Cresent Dancer means that we can have our first A ranked defensive technique. Enhancing this technique to A would mean an even greater ability to avoid attacks and stay ahead of foes, while in darkness ignoring more of the impact of even those attacks which strike us. Having this at A rank will be fantastic for our continued survivability.
And finally, my favorite wombo combo
Making this an A-ranked technique could be utterly broken. First off, "While active all Forgotten Vale Techniques are considered one rank higher, and attempts to dispel them must first dispel Travler's End." Using "Joyous Toast" with Traveler's End means that TE will be considered one rank higher for determining effects, while also buffing itself to be one rank higher. This means that TE could reach S-Rank and require an S-rank dispel before dispelling any other FVM techniques.
This also means that the nuke for ending the melody would be calculated as if it was from an S-ranked technique as well as the paralysis effect. Which is utterly bonkers.
Joyous Toast serves as a potentially powerful defensive and offensive buff, depending on the situation at hand. While slow and tedious to set up, the effects of this technique when properly used could be devastating. As in... a nuke with a radius of "very far" computing its damage as if it was an S-ranked technique.
