Darksiders II Deathinitive Edition

Once you reach level 20 you will gain access to the final skill in each of Death's skill trees, regardless of how you have spent your skill points up to that point. Simply spend a skill point in either Reaper Storm or Frenzy and you will pop this achievement immediately. You can always buy a Respec from Vulgrim should you ever happen to find yourself without a skill point to spare.
