Starting with a few thoughts:
So, I play the game and I get to a point where I'm about to enter the Endless Wall, and I freak out at one point because I missed a Djinn that can only be gotten around the time the Grave Eclipse begins. I was fortunate enough to have several saves, and one of them was saved right in Belinsk, before Arangoa Prelude was requested. After recovering up to the point where we would leave with Eoleo on the ship, I didn't think it was too bad, the progress I had lost, especially since it gave me a chance to redo my early material forging choices - notably, before I had chosen Excalibur for Tyrell the first time, and a sort-of wonky weapon choice for the rest of them minus Matthew (obviously having the Gaia Blade located in an often-missed portion of Yamata Ruins). With this restart, I was able to get a MUCH better weapon for Eoleo (which also happens to be one of, if not the strongest), the Herculean Axe, while I went for Levatine for Tyrell (a weapon that has more benefits under his usage, due to several Mars-based Unleashes as well as the almighty Centurion).
Speaking of Unleashes, for some infathomable reason, just about every time Eoleo managed to use an Unleash while he had Mythril Clothes on, he used Olympus Rage! Not only was it epic, I had set him up with the Master class, so the attack was both fast and powerful. Meanwhile, I went Chaos Lord Matthew and, following on from Golden Sun Universe's notes, set him up with a high Unleash rate. Of course, the only real thing I was bummed about by going Chaos Lord is that I miss out on the chance to use Odyssey. Doesn't really matter once you're using Titan Blade and Acheron's Grief, though...those (as well as Legend) send out pretty much the very same swords used in the Ragnarok Psynergy series.
As for my other characters' weapons, at the time I wrote this blog I had the Sol Blade equipped to Matthew (Why not? Unless you're experimenting with other weapons like I do on a regular basis...man, how I loved Void Beam Rune Blade spam...) Excalibur set to Tyrell (as I'm having fun with the weapons; for some reason when I got it, both Tyrell and Matthew already had full mastery over the weapon. Perhaps because I gave them both weapons that used the Sky Diver Unleash beforehand...), Karis with the Verdant Sword (it's a mono-elemental weapon with Jupiter alignment, how could I not? Well, one challenger (though it's not mono-elemental and still not quite as useful) - Lachesis' Rule), Rief with Atropos' Rod (Only around this point was I obsessed with rare drops, I never really cared for them beforehand), Amiti with the Sagittarius Bow (Oh, how I love that weapon in Kid Icarus: Uprising, and it hasn't failed me yet in DD), Sveta with the Anpsi Knuckles (Mythril Claw's more damaging with Unleashes, but the other weapons I have for her (Umbra/Anpsi Knuckles, Bloody Claw (Cursed)) seem to be more about status-inducing Unleashes), Eoleo with, as mentioned earlier, the Herculean Axe (It's a somewhat violent animation for Olympus Rage, IMO, as the crash comes so suddenly) and topping it off with Himi and the Tisiphone Edge (YES! More rare drop success! Now if only I had that much success with Sky Dragons and Quality Zol...).
