I haven't had the opportunity to augment any of these for friends yet but the results that have been posted on BG so far seem promising. The list below are just some of the main augments that have been reported for the NQ Shura head but there are many more that it can get that I just don't care to mention here because they suck. I'd also like to see what the HQ kabuto can get as they are reports that HQ pieces can achieve slightly better results.
Weaponskill damage (1~2%)
Attack (3~6)
Dex (1~4)
Conserve TP (2~5)
Skillchain damage (1~2%)
You always get the WS dmg augment if you HQ the recipe and one to two other augments depending on the HQ tier. HQ1/HQ2 is WS dmg and one other augment. HQ3 is WS dmg and up two augments.
I'd really like to see what else this can get and wether or not the HQ Shura head can get higher numbers. This could become a really nice head for Victory Smite.
