It is one of the best available at CL5.
It is one of the cheapest to use: 8k repair price only.
It is much stronger than shop equivalents: it gives two times the amount of parameters of a sword of retribution with 8% extra melee damage on top.
It is what I used in campaign battles as I found it is the best compromise beetween price and quality. No need to go broke on overpriced sets.
