Crafting Guide
Bow - ilvl 75: To start off you need a bow with t2 %phys (155-169% inc physical dmg) - Can either buy or pickup bases and trans/aug, until you acquire one
1) Once you have the base, just use Essence of abrasion to give it a 2nd prefix
2) Use a "dextral crystallization" with "Perfect Electricity" to craft your third prefix (any as extra works)
3) Use an "omen of greater exaltation" with a "Greater exalt" to fill your suffix (if you hit crit chance, the craft is done).
4) assuming you hit nothing, use "dextral necromancy" with a jawbone to add a desecrated suffix.
5) Now you'll use "perfect battle essence" and "perfect haste essence" - You'll keep doing this, until your suffixes are +3/onslaught/desecrated mod - if you knock off the desecrated mod, reapply it with dextral necromancy. (Keep in mind if you have 6 affixes on an item, than battle/haste essence can only remove a suffix)
6) Now that your suffixes are mostly done, this can be the expensive part. You can either settle for any unveil for low investment or for a GG bow, you keep using omen of lights/jawbone until you get t4 crit or better.
Quiver - ilvl 75: The quiver craft is mostly RNG but there's some steps you can take to improve your odds of success, just keep in mind most crafts will end up being mediocre when it comes to the quiver.
1) Perfect trans/aug quiver until 2 good affixes (flat dmg or inc bow dmg on prefix and +2, crit or atk speed on suffix).
2) Perfect regal and hope for a 3rd good affix (suffix is the ideal scenario here).
3) If it hit a bad affix, you can use a greater chaos orb and try to replace the bad affix, 2/3 to brick here.
4) Dextral necromancy + jawbone on the quiver, if it's 3 gg mods you should use an abyssal echoes
5) If you hit a good suffix, you should consider using perfect exalt+double exalt omen to finish the craft
This is the cheapest way to make a GG quiver, lots of rng steps but eventually you will hit. More expensive methods will require omen of lights, fracture and/or whittles.
Quiver - ilvl75: More expensive method
If you hit +2 lvls/crit on the suffix with t1 Flat on the prefix, you can jawbone the suffix and go for a 1/3 fracture (if you miss the fracture it's fine, just do the same steps as above) - If you fracture flat dmg, you can exalt 1 mod on the prefix and than use Essence of hysteria + essence of sinistral crystal to have 100% chance of adding bow dmg onto your prefix. The last prefix you will slam with a perfect exalt and hope to not hit accuracy. If the quiver is 5 GG mods, than you should echoes/omen of light your last suffix until you hit crit or attack speed.
Amulet - Ilvl 80 or ilvl 82 (82 is t1 resist) - The amulet craft is mostly deterministic, but expensive. You'll only need 1 fracture base to finish the craft.
1) Fracture or buy a +3 projectile amulet
2) annul down to 2 modifiers (fracture mod+random mod)
3) Chaos spam until t1 or t2 spirit
4) Add 1 suffix with dextral exaltation and 1 exalt
5) Use "dextral crystallisation" with "essence of enhancement"
6) Use your desired element catalyst (tul, xoph or esh) until the amulet is 20% quality.
7) Perfect exalt with "dextral exaltation" and hope you hit a resist
8) If you hit a resist, repeat the same step above (can use the same catalyst because the amulet can still hit all resist).
If the amulet didn't hit resist or a good stat (crit/rarity are good). Than you either need to annul or collarbone + dextral necromance + omen of light to remove the mod and go again.
9) collarbone + abyssal echoes + omen of light until you get your last desired prefix.
Helmet - ilvl 78 - Cheap method
1) Buy or perfect trans/aug bases until you hit t1 +energy shield
2) Use "greater essence of enhancement"
3) Use "sinistral necromancy" with a preserved rib
4) Unveil and take any hybrid %es
5) If the hybrid % was t1 I would use a perfect exalt + greater exaltation, otherwise just use a greater exalt to finish the suffixes.
6) If the suffixes/prefixes are really good I would finish with vaal infusers (has a chance to corrupt but the item cannot brick, just make sure to add a socket before using this).
Helmet - ilvl 78 - Cheap but random (this method allows the chance for triple t1 prefix).
1) Buy or perfect trans/aug bases until you hit t1 %energy shield or +energy shield.
2) If the prefix/suffix is good (good suffix is resist/crit/rarity) I would use a resist or rarity essence.
3) sinistral necromancy + preserved rib and than greater exalt + greater exaltation omen
4) If you hit a good hybrid prefix tier (t3/t2/t1) I would use an abyssal echoes and hope you hit a good tier.
5) Finish with vaal infusers if the item has high tier prefixes.
