Well the title says it. I want to make bazaar item but what kinda stuff do i need???

Try the guide on gamefaqs.com - there are a lot of different weapons available from selling various parts. Generally most of the parts are from common monsters and they will be can be obtained via killing, stealing or poaching.

I'm on a role with bazaar goods, in twenty four hours, I got 3 Empyrean Souls, 3 Serpentarius, 3 Gemsteels for the Tournesol, 2 adamantite, 3 death powders, and 1 Gnoma Halchon, for the ultima blade, then I got the Durandel, the Whale Whisker, the Arctacus, the Sagittarius, all the ammunitions possible, plus, I even got the Yagyu Darkblade and the Danjuro on my first kill of each creature, hell yeah.

so how did you get those certain items, from what animals and where??

There are 3 basic ways to get items - kill, steal and poach. Killing is fairly simple, just keep killing monsters of the same type to build up a chain. The higher the chain goes the more likely they are to drop an item when you kill them. Some items are more likely (or only) drop when you have bought a certain grimoire from the bazaar. These grimoires only appear when certain conditions have been met.

Method 2 is stealing, you need someone with the steal skill to make the attempt. Setting up a gambit is a good idea. IIRC the game will tell you if there is nothing to steal.

Method 3 is poaching. This is also done via a skill - however I think poaching requires the enemy to be in critical condition first (ie. HP < 25%).

A lot of different items can drop the different items - check a guide for what is available to you.

Let's see, by the way, ignore my spelling cause this is going to be a lot and I mean a lot. I got all the stuff for the tournesol in the bazaar and I won't list everything for that, I got one adamantite from doing a hunt and stole one from the first trophy rare game you can fight. I got 2 emperor scales from a wyrm of sorts in zertina caverns, 3 lifewick from ghosts at the pharos at ridorana, then, I got 3 death powders from bogeys in the z caverns, 1 halchon from a leschach entity in the paramina rift during a snow storm, I got a yagyu darkblade from the bombshell rare game in the Lhusu mines, 3 mythrils from mythril golems in giruvegan, 4 aquarius gems from Golems in the feywood and 3 corpse flies from some undead dragon in the subterra levels, got 3 yensa fins from yensas in both sandseas, got a couple of wyvern wings from areonites in the lhusu mines, a salamand halchon from the spie judy in the magic shop or something in Archades for helping her with the sidequest at Nalbina, let's see, got a beastlord horn from the Catoblepas, got one from Ekidu in the Gilgamesh hunt, and one from a random humbaba in the mosphoron highwaste, also, got the danjuro from larva eater, a little tip, the weapon is just for show, sell all the loot explained, you will get a magnificent arsenal, now getting the money to buy it all will be a far different story.
