Help Me Understand These Screenshots

Hi folks,

I'm incredibly confused about how to build a T4 Alpha ability. Here is a shot of my current advancement of the Cardiac tree. I have a Notice of the Well, 30 shards in inventory, and am trying to figure out how to get to the Cardiac Core Paragon.


Screenshot of what is needed to build T4:



Screenshot of the base of the Cardiac tree:



Question 1: To get to the T4, do I have to build a new T1, T2, and T3? Is that what it means by "Cardiac Partial Radial Revamp"?

Question 2: Do I need this exact item, or just any of the items that is not the T3 I currently have?

Question 2: Aren't Biomorphic Goo, Detailed Reports, and Supercharged Capacitors made with threads not shards?

1. You need to T3 twice, then you can create your T4 with more of the salvage needed.

2, Yes you will need all of the items in the list. you can use either list, but the two cannot be mixed.

3. Yes, in the second pic are indeed made with threads not shards, for that set of salvage. but as in the first pic, you can use just shards for the other salvage. Or you could just get lucky with drops, or do the TF's for the first set and use Vanguard merits for Any Grai Matter you may need.

Hope this helps.

Well, to craft a very rare(T4) , you need to have 2 any rares(T3).
That means, if you already have a rare(T3), you need to craft another rare(T3) from scracht, then convert them into the very rare(T4) with more Incarnate salvage and a Favor of the well.
I know, it sucks. I dont have any very rare(T4) on my alts yet. Not in a hurry, Ill do it when I have the stuff...

The only restriction is that the second T3 must be a different one from the same tree

e.g. in your screenshot you already have Cardiac Partial Core Revamp so you need to build any other Cardiac T3 except that one and then scroll down until you find the recipe with both coloured blue.
