Need help with training to make a Lora

Hello, I need help with AI training to create Mithril outfits from Cabal Online. I don’t know anything about training — I already use AI to generate content and have some experience, I use ComfyUI. I’m looking for someone patient who can help me learn how to train the AI. If you speak Portuguese, that would be wonderful. But I understand English well too.

I have an image I found online — it was posted on a Facebook page by a guy who’s developing an upgrade for the game and trained an AI using Flux. I’d like to do my own training as well.
