Are the weapons missable?

[Seph]

I'm interested in completing every achievement, and apparently I need every weapon to get every skill. Can I actually miss any of them during my playthrough?

The Dragon Baller achievement - Synthesize all Dragon Stone weapons
These weapons are only available at final game, and you only need to craft (synthesize) them for this achievement

Other than that, each weapon in the game is assigned with a skill, thus you still need to craft other weapons (not necessary all because of duplicate) to learn every skill for Stealer of Weapons' Souls achievement. In other words, you focus on getting ones that have skills you haven't learned, the rest can be sold for your need.

And to learn a skill, you have to level it up once.

Skills aren't missable. Bestiary entries are what you need to watch out for in 100% -- the tutorial, and minions during the Wind Shrine bird and Water Dragon are easily missable.

Alright, thanks for the info. It should be a pretty smooth 100% if the only thing I can miss are a couple bestiary entries. And the Tia escort achievement, but I got that one outta the way already.

You can miss the quests too.

You can't miss any weapon, but there are some weapons which can only be obtained once, most notable is starter weapons. If you sell those weapons you can't get them back, what makes you miss out on skill if you haven't learned. So I would recommend to learn skills as soon as you get new character
