Step 1. Get 3 level 105 maga and ornament them.
Step 2. Get a low ranking skill force magatama and ornament it. You should choose one that leaves you with just enough chakra to use 3 level 105 maga.
You may potentially substitute a low ranking skill force magatama for a himono if the himono is ornamented with fire, wind or holy.
You may potentially substitute a magatama for an element magatama and adjust your build accordingly. Only magatama with high amounts of element are beneficial.
If super low on chakra, use an affinity magatama instead of a low ranking skill force magatama. These generally cost less chakra.
The end.
