My Grimoire is 4820, with 15-20 more points nearly achieved. I can run Relic on Templar, Gate keepers and Atheon flawlessly, I can be Sword bearer with ease (as a level 32) I can run Aura on Warpriest flawlessly, I can do 1 ord and 6 orb Strat on Golgoroth, I can do any job on Sisters and can beat Oryx with any Stratergy, I can kill my and the other Knight and still get back to the middle and not die. I have an above 1.0 on my characters in PVP (I know it's not great but I don't sweaty all the time) High Grimoire does infact mean a player has more skill than someone with low Grimoire (if those 2 players have the same amount of hours played)
