What's that gemma?
Minor improvement to the Sunken Continent skip: Because the music in the Grand Palace is the same as that which is outdoors, I can remove one instance of the game halting to load a new song by waiting one more screen transition before switching back to the original file. So I enter the Sunken Continent area, swap to the just-got-Flammie file, enter the Grand Palace, leave the Grand Palace, swap back to the real file, and enter the Grand Palace, and now I'm in with a functioning rope, about 1 second faster.
I can get Lumina to level 3 at the price of only menuing time (plus walnuts, which again are just menuing time), no screen transitions needed, by simply casting Lucid Barrier on herself (not on the whole party) while the Sprite is casting spells. I can cast a Lucid Barrier on the whole party at the end of boss fights and during the Sprite's Crystal Orbs in the Grand Palace.
I have tested the Lucent Beam strategy by starting from my previous run's first Frosty Forest file, and it seems to work, but right now I'm finding myself unable to make it to Spikey Tiger so there's no completed runs to show. One thing I'll note is that a level 1 spell is insufficient to kill the Boy with the Wall Glitch if he gets 60k experience, so either I'm going to have to cast the spell I got up to level 4 during Buffy (at a waste in terms of Magic Experience), or I'm going to have to remove the "improved" wall glitch as an available backup strat, and instead just make sure nobody dies during bosses.
There's also the minor irritation that I either have to use the girl to restock the Cups of Wishes, or else I need to wait for the Boy to fully revive before he does so.
Lucid Barrier works on special moves, like Balloon Ring and Freeze Beam. Attacks which ordinarily inflict a status effect will leave you alone if Lucid Barrier blocks the hit. For reference, Lucid Barrier grants a total value of damage that it shields before breaking, not a certain number of attacks it blocks, with the particular attack that breaks the shield still getting blocked. I'm not certain about moves that cause your character to become incapacitated before the hit is scored (the various eating attacks, of which only Buffy is relevant). Unfortunately, some of the bosses mentioned in your post occur before Lumina is acquired.
