Making boosts for alpha slot

I have Ancient Nictus, Essence of Incarnate, and Hero 1 DNA and 30 shards. I am an earth/rad troller. I want to boost my accuracy. What is the most I can make with what I have listed?

I don't want to do this wrong, as it's darn hard to get the components, and I don't want to waste anything.

Thanks for your help.

4 shards -> Dimensional Keystone
Ancient Nictus Fragment + Dimensional Keystone + Essence of the Incarnate -> Nerve Boost

This gives you a 33% enhancement to accuracy. From here, you've got two choices, neither of which gives you any additional immediate accuracy enhancement. First you can build along the Nerve Core line, for an eventual 45% enhancement to accuracy, 33% to hold duration, and 20% to defense powers:

4 shards -> Dimensional Keystone
4 shards -> Ancient Nictus Fragment
Ancient Nictus Fragment + 8 shards -> Incarnate Infused Nictus
Dimensional Keystone + Hero 1 DNA Sample + Incarnate Infused Nictus + Nerve Boost -> Nerve Core Boost

Second, you can build along the Nerve Radial line for an eventual 33% enhancement to accuracy, hold, taunt, fly, and confuse, and a 20% enhancement to defense powers.

4 shards -> Essence of the Incarnate
4 shards -> Penumbra of Rularuu
4 shards -> Dimensional Keystone
8 shards + Dimensional Keystone -> Infinite Tesselation
Infinite Tesselation + Essence of the Incarnate + Penumbra of Rularuu + Nerve Boost -> Nerve Radial Boost

Does all that mean that I don't have enough yet to build anything worthwhile? Or I can build something now that I can put in the alpha slot, then further build it when I get more components? I first build the Nerve boost, then work toward getting what I need for the Nerve Core Boost. This is totally confusing to me.
