It's the middle ground between the PGS and the Mura. It's R1's are the same as the PGS', but it's R2's are close to being the Mura's R1's. I love the reach and sweeps on it, and the fact that it scales only makes it more amazing. The only downside is the split damage that leans mostly on it's fire damage (humanity scale)
It's a Falchion with split damage. +15 a Falchion and go nuts with it. Puts out a lot of damage really quickly, and it'll stun in a hurry. Not just underrated, but underestimated.
