i think the scorpion claw is where the bonecrafting comes in and i believe your bonecrafting would have to be at a decent level to +1 or succesfully synth this for that matter ^^.
I am an Elvaan Ranger= Very Low Accuracy...so I always need anything +1 to help me hit the bloody monster. The Problem I have noticed is I can't resell any of my previous bows because I need Powerbow+1 for Garrison...and to help friends w/ Rank 3 Quest...Can't Sell my Greatbow +1 for the BCNM30 quest. PLease help me out what is a great monster or farming I can do... Ranger40/Theif18
I have tried to craft this several times. I am 59 Woodworking and have failed about 25% of the time. That, coupled with the fact that I have recieved bonecraft skillups while crafting this, leads me to believe that this synth uses Bonecraft as the secondary skill.
