What is Soulbinder trait?

[Sysquella]

I was looking at icy veins, and I saw a trait on the other blade called Soulbinder. That doesn't show for me, is that something you get when maxed out?

You're probably referring to the final trait that is just 20 levels of raw damage boost. You can only put points into this after you put points into everything else, and will show up in your book sometime between 18 and 24 ranks purchased.
