is possible add random sockets ?

i have

Eth 2x 0s items can i make sockets in

Horadric Cube?

Yes, you can see the recipe here:

Recipe: Add Sockets to Normal Weapon

The maximum number of sockets depends on

• the type of item
• the item's ilvl (where / from which monster it dropped)

For both

Colossus Voulge and

Stygian Pike the max is 4 (all places that can drop them naturally have high enough level to always have max sockets = 4), so it will get 1-4 sockets (50% chance of 4 sockets).

Here is a list of max sockets per item type per ilvl range:

but you cant use recipe on superior items afaik, i know your items is not superior, but just in case you found any
