For example, weapon proficiency increase with the use of the certain weapon type and we have 9 different weapon types, this can be combined with Weed Wacker, Not-So-Secret-Arts and Search and Destroy trophies, where you can use a certain weapon and defeat a clamp with a precision skill and when you reach 500 proficiency you switch to another weapon. Neither a Test Player nor an NPC: Reach Affinity rank 2 with 100 people. Search and Destroy: Land a total of 500 hits on enemies with the charge gauge at max. Not-So-Secret-Arts: Unlock all Sword Skills in all 9 weapon categories.
Some of the Grindy Trophies: Weaponmaster: Attain a total of 5,000 Weapon Proficiency Most of the trophies in the game are grindy so my best advice is to try to hit more than one bird with a single stone. Interact with any Relic Statue (Blue icons) you see as some can be for the Sacred Art (Magic) which you will unlock fairly early, also then use these Sacred Arts such as Tail Wind and Create Metal to get to hard to reach areas (Relic Statues and Chests). ROADMAP Learn the combat mechanics as it will let you finish your battles more quickly and blast your way to Chapter 2 but i highly recommend leveling up as you will be facing a boss after a boss without a save point in between near the end of Chapter 1.
