hi when making special items do you need to have legendary items to make legendary item

eg .... to make Ragnars Helmet you need Fur hat

does the fur hat need to be legendary

No, but it is a gamble...

When you select material who are not all legendary, you can see a % ...  this % is the chance related to the final result...

in the example below, you have 50% chance to have a rare, 25% to have a epic and 25% to have a legendary serrated blade 

ANESFAN, is right, but in practice, never use non-legendary materials and items to craft special equipment. It just wasting of your time, energy and materials
