Hollow Knight (EP)

This will probably be the last set of trophies you will get before attempting the Pantheons. In Greenpath, there is an NPC called The Hunter who will bestow on you his Journal. The Journal will contain all the enemies you have fought in the game so far, including bosses and creatures that don't attack you. Keen Hunter requires you to find all these enemies but True Hunter requires you to kill them several times to unlock a small excerpt from The Hunter about that creature. Fortunately, DLC bosses, such as White Defender, Grey Prince Zote, Grimm and the Pantheon bosses are not required to receiving this trophy but it is strongly recommend that you avoid Grey Prince Zote like the plague so he won't show up in the Pantheon of Hallownest and make the game unfairly hard (Credit to MrPeanutButter for this tip).

Some enemies can only be recorded via hidden interactions, such as Goam or Garpede. It is reported that you don't need to add Hollow Knight or Radiance to your list so you can get it without them. Compare your list to this and if you find any you've missed, then go and find those missing entries. You should receive Keen Hunter when you've found the last entry. When you've done that, kill the required number of enemies in the Journal until they all have an entry to them. Once that's done, visit The Hunter once more and he will give you the Hunter's Mark. Receiving this item will also pop the trophy.
