Dusk Diver 2

MISSABLE

IMPORTANT NOTE: It's unconfirmed whether this is a glitch or how it was intended, but you may get this trophy the first time you synthesize any Level III Orb. I got it upon synthesizing a Critical III Orb. It's possible that this was a healthy glitch, but it's more likely that "Rank 5" doesn't necessarily mean a "Critical V" Orbs, but instead the Rank may be referring to a different internal ranking system.

One of the features in the new equipment system is Orbs. These Orbs are essentially gems you can place in any piece of equipment that has Orb slots. (marked by a dark circle on the top-right corner of the equipment info screen; see below).

Starting in Chapter 2, you'll be able to begin crafting Orbs at the Tumaz Mart. At first, you'll only be able to craft very low-level Orbs, but as you progress through the main story, higher level crafting recipes will gradually unlock.

Crafting (AKA Synthesizing) Orbs requires materials, which are the Chaos Beast material drops you get from killing Chaos Beasts. Additionally, each new level of Orb crafting that unlocks has two recipes. Both recipes will craft the same level, or the same pool of Orbs; they're just there to give you another option with different materials.

To get this trophy, you'll have to wait until at least Chapter 10, when you unlock the Clear Orbs recipe, because that's the first time you'll be able to synthesize Rank 5 (or III) Orbs. Just spam the recipe until you get one.

TIP: If you don't want to waste all of those materials, you can reload your save once getting the trophy, since it really doesn't matter to keep hold of those Orbs.
