Hi, I just wanted to share with you how you can easily craft an Attribute Amulet with 30% Increase of the Attribute of your choice. It's extremely easy and kinda cheap to craft. While it's certainly not BiS for Attribute stacking builds, I use one with strength for my Baron Str Stacker and it nets me over 300 Str on a budget.

So let's get started: Step 1: Get an ilvl. 75+ Simplex Amulet. Slam it with a Warlord's (Str), Crusader's (Int) or Redeemer's (Dex) Exalted Orb depending on the attribute that you want. Then Chaos spam until you hit "9-12% incread Str/Int/Dex". Make sure that you don't have another influenced mod on the item.

Step 2: Get an ilvl. 68 Amulet with shaper influence. Alt spam until you hit "6-9% increased Attributes". Again, make sure that it's the only influence mod on it. Alternatively you could just buy one with the mod.

Step 3: Use an Awakener Orb on the 2 amulets so that the Simplex Amulet ends up with both mods.

Step 4: Check if you have an open Prefix. If you don't use the Harvest Craft "Reforge, keeping Suffixes" until you have an open Prefix. Once you have one proceed to step 5.

Step 5: Bench-craft "Suffixes cannot be changed" and then scour. You'll end up with only the #% incr. mods.

Step 6: Divine until you hit 26% increase (It's 15% Str/Int/Dec and 11% to all because of the Simplex Implicit.). This should take you an average of 9 Divine orbs.

Step 7: Use Intrinsic Catalysts to reach 30% increase.

Step 8: Now you have your Amulet with 30% increased Attributes. You can craft the Prefixes however you want. For mine I used a T4 Aisling to get a life mod. Aisling is easy to farm and you'll unveil a life mod with a 54% Chance making this a really good option. If you don't hit life you can just repeat step 5 and try again. After that I crafted the "20% increased Es" mod on it. But you can do the Prefixes however you personally want. (Aisling + Bench is a really good option tho).

Edit: As u/anne_doballina has pointed out in the comments it's actually a 30% increase of all attributes and not 26% if you use Catalysts.
