Like you spooky I don't really go into the crucible unless it's needed for a quest. I struggled with this at first but here's a couple tips that I hope help. 1. Make sure you have plenty of time - it easily took me 20-25 games to get it done. 2. Play rift or control - people group up in these games making multiple kills much easier. 3. You only gain or lose IF the last word is equipped - so that means you can die 100 million times and lose nothing if the gun isn't on you. 4. Play defensive and wait for your super - I would wait until my super was charged (storm caller) then equip the last word and attempt to get multiple kills. I've you get 3 you'll gain around 10% (triple kill, not just 3 seperate kills) I had a couple times I got four or five and then gained 20-25% in a single super use. 5. UNEQUIP THE GUN - once my super was done I quickly hid and removed the gun. I hope this helps :-)
