Hello, As a heads up, exotic weapons do not grant grimoire score, only the card. For your sidearm kills, are you attempting to get kills in PoE; PoE is like a raid and kills there don't count towards grimoire. For your hydra kills, only red health hydras count towards grimoire, majors or ultras do not count towards grimoire. I'd recommend killing the hydra outside the black garden gate for your remaining kills Hope some of this helps
