So after what felt like forever I finally gathered all materials needed for my exotic sword. Here's some tips I learned along the way. 1. Get a ghost that that can locate the materials you need, doesn't matter what level it is. 2. Have the subclass equipped for what ever ability kills you need, this way you can jump in public events and use your super/abilities to rack up some % Lastly and this is the big one 3. Every time you locate one of the 10 legendary materials you need move areas. Maybe it's superstition but after it took me forever to find the first 4 I started doing this and I would find a piece in the first 4 to 5 materials in each new area. Hope your collecting isn't as painful as mine was.
