To do Savage content, you need at least 603 accuracy, it starts at 550 at A5S.

Other than that, go with Crit and SS.

For my BLM i don't have much in terms of gear but i have 400 Det, 1049 SS and 832 Crit. my acc is at 517 but im working to up it up.

With this SS i can do what i normaly do, Blizzard III (wait a bit for your MP to be full) > Fire III>Fire I (For the proc)> Spam Fire IV then end with Fire III. This normally allows you one Fire I and 4 Fire IV and still leave enough time for the FIre III Proc to go without Astral Fire going down, equaling to full damage, this without Ley Lines.

With Ley Lines it gives me time to, at the end, Convert, 2 more Fire IV then back to Blizzard III > Blizzard IV
