First I'm going to tell you this is in the wrong section xD. No biggie though really, just more likely to get a response in the Monk section.
You get there by going to: Tips&Tricks>Full and Special Classes>Monk
Gonna tag mr
Jeancarlo here to move it to the Monk section
.
On to the actual question though now
Start working on CRT now as your AGI will be plenty high for a long time xD. I'd recommend at least 180 before working on anything else. AGI is a very good investment in general and will continue to be your highest stat as a Claw build.
As for gear:
It's fairly easy to get to +7 using Mythrils so might as well do that for your Sion Capell. I can understand holding off on +8-9 until you get a more steady supply of Orihalcum. The boost in ATK you get is more per refine the higher you go. Sion Capell is the best Claw until higher levels so you can keep using it for a long time.
Schwartz is fine for now. You will want to save for something else though. Ultimi is the best option by a good bit. Yang Garb is a downgrade of Ultimi basically. Dunkelis/Dragon Mail are also okay.
Replace Anniversary Brooch with something that gives ATK/Crit Damage or possibly Blancheur(this is from Sauro Medal+, you need 20 but it isn't guaranteed to be slot). Blancheur is for MP and HP mainly but it helps when you get Rush. Asura Stole is a decent option. The more expensive options would be Variant and Glory Cape.
Seahorse Bangle is great for HP at lower levels. If you feel like you need HP still then keep using it. You will mostly likely stick to just this for a while. After you get a Wisdom Bangle and/or Dragonewt Bangle from MQ then using those with a WoL xtal will become what you usually use.
