AUCTIONS. Seriously you can get AWESOME shit early on.[/QUOTE]
QFT.
You can get majority of best weapons/skills on auctions. Plus, winning the auctions isn't that hard to do. All you need is fulfill the bonus to get 5 point chips and try to remain a champion on one area to get one free chip or you can buy chips with your clan points(which can be easily max out with recycle quests). The AI is incredibly stupid when it comes to auctions. I seen 8 opponents with 50 of every chip(1,2,3,5). Surprisingly, they only use one point chip or skip during the whole 4 set rounds.
[quote name='DQT']Hey are there a lot of missable items in this game? If there is one thing I hate in RPGs, it is missing items. I remember in FFTA you had to get the Cinqueda very early in the game (it's rare early in the game but common later) in order to get the steal ability skill. You then had to use it to steal the steal weapon skill. Otherwise you would miss some cool weapons that could only be stolen early in the game.
I had to play that game with a faq most of the time to maximize my inventory of weapons. I'd prefer it if they were more lenient here.[/QUOTE]
Nothing missable except the light lute. You can get the first light lute when you can fly to another world (via by airship) then complete a few quests. Hurdy(moggle) will ask you to build an instrument. Don't build an instrument yet, go to SamtDalasa Buff, you will see a quest pop up(I forgot the name). Afterwards, craft an A rank item instead of B rank item. I don't know the location for the second light lute.
I'm almost finished with this game. Now I have over 250+ quest complete by using dispatches more frequently.
