@Silent133 Hello, first of all, just ignore what AshesOfAden writed. He select alot of expensive items that its not worth to you spend unless you have at least "ok gear".
The items that I will indicate are the items that I consider "the basics" for each character. Keep in mind the following, it's better to have a balanced char than a char with just one very good/expensive item and being useless. So here we go, starting with the basics:
1. Your circlet its ok;
2. Top Kaliel ok, but you need change your talismans as much faster you can. (Insanity, Seven Sings, Sayha lv. 8, Venir lv. 12) these are the basic ones as their combined stats are pretty good and they are "reasonably cheap". In addition to them, you will still have 2 slots that you can choose between a Talisman Abundance lv. 1 and some other 30d;
3. Seed lv. 3 it's enough for now, leave to upgrade this item (seed lv. 4) later;
4. Top brooch ok but you need to finish your greater jewels set. At least greaters lv. 1, dont spend too much on top jewels or jewels lv. 5, its not worth for now;
5. Top book ok, focus on put all your artifacts +4. Here is an observation, you said you are following the build of p. critical dmg, however, I think it's good that you start migrating to p. skill critical dmg / p. skill power, because when you finish buying these items from the list you will have good damage to use skills.
So, buy the 11% p skill critical damage artifact, but if you want to continue building p. critical dmg, buy the artifact for that build;
6. Skills +20 always welcome and it make a huge diference;
7. Your elmore cloak its enought, just make sure to take a right augment. If you go to p skill critical dmg build and dont have Dragon weapon, you will need one cloak with p skill critical rate augment, if not, try to take one with p critical dmg. In case of you buy one Dragon Weapon, you can use one cloak with p skill critical dmg augment. (Of course +15 elmore its a game change but its really expensive and its not worth to take it if you dont have "base build");
8. Good set and tersi's, keep it;
9. With the right build one bloody/limited weapon +12 its enought to kill on NZ. in my opinion finish your build and after try to take one DW lv. 1 or one limited +21;
10. Belt ok, enought for now.
11. You would try to take +5 shirt, its so huge diference but this but it would bother me haha;
12. Base jewels: Blessed atlas, B. Valakas, Angel ring +6, Fallen Angel ring +6, Fallen Angel Earring +6;
13. Dyes at least lv. 4 set (P. Skill critical DMG - P. atk - P. Skill Power, in case of p. skill critical dmg, if not, change your p skill critical dmg to p. critical dmg);
About augments it will depend of what build you will choose, but keep in mind it:
This game is base on criticals, so if you want to play as p. critical build, be sure to have high % of P. Critical rate.
P. Skill critical dmg build follow same rules.
Just a point, Dragon weapon have good bonus of p. skill critical rate and p. critical rate, so if some day you buy one, you will need less rate (skill or not).
Don't be fooled by very expensive or very advanced items that alone don't make the slightest difference, a well-built character will be much more worth it.
Follow this line of reasoning and you will be very satisfied with the result, I assure you.
