Hi again Degamad.
Your weapon looks solid so this is a good start ( try to get 15% P Skill Critical Damage ) might cost you couple of Bills but the damage boost worth it .
Your dyes are also ok, no need to waste more money now. ( 117 Str and 77 Dex is pretty balanced ) .
Make sure all the skills you use are at least + 10 enchanced .
Jewels can boost your damage a lot. if you can afford it get a 30 days Rare accesory pack and try different set ups to see highest damage output. For example Octavis Warrior Necklace vs Blessed Valakas will give you around 15% more damage ( 50K damage with Octavis Vs 58K damage with B Valakas ) . But you need to prioritize . Octavis warrior neclace is around 1-1.5B, but Blessed Valakas will set you back around 30-35 Bill atm.
Remember Ln2 was designed as a grind game, so it requires patience and time. Of course due to the Pay to Win lately , someone can throw $ 1500.00 and get +10 Bloody set , +12 weapon + Full epics in 10 minutes. It took me 1 Year to Bless my Valakas necklace back in 2014 but it was a rewarding moment .
A Ruby lvl 3 and opal lvl 3 will be a decent damage b00st . ( 2-4 % ) . Red Cat is great but extremely expensive ( i wouldn't bother at this stage )
At the moment there are not cheap Noble stones in the market to nobless your circlet, so wait for it. Altough might me cheaper to buy a +5 Noble authority rather than try to make it. NCsoft enchant rates are not the best. ( Last week a +5 Noble authority was sold for 12B , imo very good price ) . Circlets are better than even Dual stat accesories cause of the Attribute attack.
And all the above are just basic. The you have so many things to throw your adena at. Venir Stage 15 ( preferably ) , Abudance lvl 1 , Longing Talisman ( Insanity if you can afford ) , 7S Talisman ( Attribute attack bonus ) .
Ultimatetly it's your decesion how you want to progress in the game. The quide mentioned above is pretty good to follow ( some things out of date cause of new items introduction ) .
Remember it's a game , enjoy it as much as you can with what ever you have
