Having a high grimoire score does not mean you are skilled or better than anyone else. Grimoire score is destiny's version of stamp collecting. You don't do anything special to achieve a higher grimoire score other than repeat the same shit/grind/best your head against a wall. Yet somehow player think it gives them some magical mystical powers in game. By bragging about your grimoire and/or pointing out other player's scores you are simply proving how much of a lifeless nerd you are. Prove me wrong.
