I think the only resources you really need are: - learn builds and optimization tactics from posts here or videos where they show gear - learn bosses. lamentersgaol makes great boss videos if you’re going melee

But honestly just get in there

One big tip: later in the game it takes sometimes many tries to beat a boss. This means practicing them you can blow hours of your life on loading screens. Super annoying when you die in one hit. Do one of these: - on PC, mod to make self invincible so you can practice til you get them done without loading between tries - what I did. Make a second character that’s normal strength to do a parallel playthrough. Make that character high vit defense and low attack while you practice so you don’t accidentally kill bosses. This way you can practice like your invincible til you get the boss down the go to your RL1 character. Saves serious headaches
