On xbox. Hell yeah I finally did it, I've also estabilished I have no life so that's a plus. 2815 is currently the max on xbox, I think its 2840 on ps4 I'm not sure. If you say i've got score missing its because certain grimoire is glitched out or bugged. EDIT 1 : If anyone needs any tips on how to maximise their grimoire score effectively, just send me a message or reply to this post, or you can use destinytracker.com grimoire checklist tool to see what you are missing. Also I'd like to point out that getting 5000 kills on all three classes in crucible for the grimiore score actually helps you out, it ends up opens your mind up to other two classes if you've not used them at all as it did to me. EDIT 2 : I have nearly 30 days playing time if anyone is wondering. Though Im just estimating to be honest. EDIT 3 : Found out max for ps4 is 2870. Xbox max is 2840, Im on 2815 which is highest I can get, due to other cards being bugged and not popping up. EDIT 4 : To clear up a misunderstanding about me reaching max score. EDIT 5 : Just so you know I have a psn profile for destiny too incase you saw that my grimoire was low. Just switch over to my xbox profile to see the grimoire score at 2815... Thanks to jester6598 for this. [quote]2870 is max for ps only at the moment since ps has access to the timed exclusives, the max that Xbox can reach is 2840 but due to bugs in coding certain cards don't proc and that causes Xbox to only be able to reach 2815. Once Xbox gets access to the timed exclusives, then they will supposedly be able to reach 2870... If the bugged grimoires get fixed... He has achieved the maximum grimoire score available for Xbox players[/quote]
