Guild Wars 2

I was wondering if there are any way to get the Grimming Shield besides the chests, since I opened 30 and didn’t get anything besides tonics and boosters.

You cannot craft the skins from the BL chests. But I think your best bet would be to simply save up and buy the Shield from the trading post. This pretty much goes for anyone thats wanting a specific skin from the chests – The chance of getting a halloween skin is low, and the chance of getting the specific one you want is much lower.
