Don't bother... runecrafting has lost it's value at 91. I suggest working hard for 85 dunge or telegrabbing white berries north of corp. Wear only games neck, ring of dueling, and a staff of air...
Have about 200-300 laws in inventory. Games neck to corp, run about 10 feet north, tele grab the two spawns of whiteberries and bring a bob familiar. Run back down to corp, ring of duel to cw, repeat.
