Well yeah, that's great if you have it. Until then though, it's great. If you can obtain a Rose Strap, I'd do it. I used it on my old character, and was very pleased.
Eh, I don't think I'd waste the money on that. I'd rather spend the small amount of extra cash, and go for something superior. If you really wanted to spam for an amazing mantle, I'd go for Amemet+1's. That's if you're trying to do this on a budget. If no real issues with spending the cash, do Forager's.
And Busterblade, your gear isn't all that exceptional either. Please refrain from being such an ***.
I need a bit of advice regarding back pieces for Samurai.
I currently TP in Amemet's Mantle +1 and then I swap to Smilodon Mantle +1 for weapon skills (except for Rana, which I just keep the amemet's mantle +1 on).
