Application of Radiant sources to the structure is calling for 1:1 at opt. Surely that is suppose to be 2:1 right?
I have not tried any other t6 resources yet. I'll report back if those are asking for 1:1 when I get to them one by one.
**update
Application of Radiant spheres calls for 2:1
I have opt. skill to make these. I should have added that.
