So I am about to jump into Garuda for the first time and I would really appreciate any advice my fellow tanks may have. I am avoiding watching any videos on YouTube simply because I don't want any of it spoiled for me.

While I don't want to see any cut scene/visual spoilers. I would like to know the mechanics for each stage.

Additionally, what is the recommended defense rating and health level for this fight? Currently I am sitting at 2800 range for health with 428 defense rating. Should I farm Stone Vigil a few more times for gear or am as prepared as I can get?

Thanks guys!
