Hello. How would you put on a new character, what would you invest in first to start building good damage?
There is no full guide to that, it depends how much you can invest or farm adena. First is to buy all items that are not expensive and providing lot of boosts to your damage then to start to fill all empty slot in your character inventory panel. Later, with more adena, you upgrade step by step your current gear. You work onto enchanting your skills, learn forgotten skills. Try gamble for a good homunlukus and if you have massive adena, you can work onto collection and tome of hero. I don't even know what type of character you have, and what gear are you wearing.
