Void Stone Upgrades

Important Notes
-One [20% Void Stone] costs 1.50 EB when there is no sale in the heaven repository.
-It is important to know that a [20% Void Stone] will NOT prevent a failed socket attempt from breaking the weapon. It does not work like a lightbender stone.
-20 Void Stone Fragments makes one [20% Void Stone], therefore if using only Void Stone fragments, just multiply the number of [20% Void Stone] by 20 to get the required amount of fragments.
-There are no 5 or 7 Socket Void Stones, you must use a 6 to reach 5 sockets and an 8 to reach 7 sockets for a 100% success rate.

Individual Stone Costs and Forge Fees
[4E Void Stone] = [100g] + 2 x [20% Void Stone] (3 EB)
[6E Void Stone] = [250g] + 2 x [4E Void Stone] (6 EB)
[8E Void Stone] = [1250g] + 2 x [6E Void Stone] (12 EB)

Raw Total Costs of Each Stone
[4E Void Stone] = [100g] + 2 x [20% Void Stone] (3 EB)
[6E Void Stone] = [450g] + 4 x [20% Void Stone] (6 EB)
[8E Void Stone] = [2150g] + 8 x [20% Void Stone] (12 EB)

Costs of Socketing a piece of armor from 1-8
1-4 Sockets = 4 x [4E Void Stone] = 8 x [20% Void Stone] (12 EB) + [400g]
5-6 Sockets = 4 x [4E Void Stone] = 8 x [20% Void Stone] (12 EB) + [900g]
7-8 Sockets = 4 x [6E Void Stone] = 16 x [20% Void Stone] (24 EB) + [5300g]
therefore...

Armor 1-8 Costs:
32 x [20% Void Stone] (48 EB) + [6600g] in forge fees.

Weapon 5-8 Costs:
24 x [20% Void Stone] (36 EB) + [6200g] in forge fees.
