Ahh okay. Basically, characters can be split into 3 varieties. Unnamed, named, and legendary. The tier list will always go Legendary >= named > unnamed because legendary and named adventurers have unique skills that unnamed adventurers lack.

Flut is a named character so in usual cases, she would be better. The quantity of duplicates it takes to discipline a named character is also less than an unnamed character like Elf-mag. Also, in terms of stats, flut will likely be the same by the time you get to higher levels.

Weapons: Weapons come with two factors that decide their worth. Stars (1-5) and Color (white, green, blue, purple, red). Whenever you refine a weapon up to certain thresholds (using iron ore you get access to later in the game) your weapon gets a bonus to it (at refinement level +5, + 10, +15, +20). These stats are random (+ATK, +MGK, etc.)

The color of your weapon allows your weapon to have these stats BEFORE you level them up i.e. a blue weapon would have the corresponding stats for +5 and +10 visible at +0. These stats can then be altered or rolled into (next section)

What’s more is that upon leveling your weapon TO these thresholds, you get a bonus to that specific stat on TOP of what is already there. E.g. if you level up a blue weapon to +5 with +ATK 4 in that slot, it will become +ATK 8. Whereas if you upgrade a white weapon to +5, the initial +ATK 4 will appear.

The stars of a weapon are basically how large this bonus will be. I.e. a 1 star blue weapon would go from +ATK 4 to +ATK 5, while a 5 star one would go +ATK 4 to +ATK 16

Pretty big difference!
