Average stats, low Shot ATK, the bad Zeon and For Urban Area word tags, and a very, very unique part trait. The part trait gradually recovers Armor while you are below 60%. This is the first part trait to passively recover Armor over time, which normally is a very powerful effect, especially on longer fights. There are two issues here. The first is that missions in this game generally don't last very long, especially at the top end of content, like Arena, meaning you don't get to benefit from the trait for long. The second issue is the rate. You only heal 10 Armor per tick. Unless it ticks multiple times a second, the actual healing amount isn't really going to make a difference, since it heals less than 1% per tick. Granted, I don't know the timing of the tick, but some of my suits with no gold parts have between 3000 to 4000 armor. At 10 Armor per tick, that's literally 0.33% per tick on the 3000 Armor suit. So if it heals 3 times a second, that's only 1% health per second healing.

All in all, the part is very unique, but not very good in spite of that. Maybe pick it up for a Supporter suit, assuming the trait to boost recovery works on this trait, but I doubt it. It would normally be a D if it wasn't for the trait that is the sort of thing that could become very good in the future.
