[1.5.10] Tentaclomancer build (Insane/RL winner)

With Forbidden Cults, if you side with the assassin lord instead of saving the merchant, you get access to a randart crafting bench. Basically, you select a pink/orange item from your inventory and it will allow you to replace ~3 egos on the item with new ones of your choice. Lesser and greater egos have separate pools of replacement options and separate pricing. The price increases as you make more modifications to the same item. Just like with merchant randarts, you have to return from the East before it becomes available. Upon returning, you'll get a note with a code to enter in the Strange Portal.

Keep in mind that you can't take any old randart and craft the perfect item. It seems to only let you modify a subset of the properties on a given item, so you generally want to look for items that mostly have stats you want already so you can just modify one or two unimportant stats to get something better. In some cases, I wasn't able to improve a given item because it only allowed me to modify the egos I wanted to keep. If you really need a certain ego, you could save trashy randarts and try to craft them into something decent though.

Hmmm. Is mastery a selectable choice? I’m guessing no, given that all your masteries are 1.0.

I didn't end up trying necklace or pickaxe crafting because I didn't find any decent randarts of those types. I'm not sure about the options. My guess is that if it lets you pick a mastery ego, it will be for a random category.
