So I got to Chapter 13 and warped back to Gran Pulse to grind up a bit. How much preparation do you think I should do to be able to easily tackle the last chapter and bosses?

last bosses luck, higher life



just max all3 of your main crysterium and second tier weapons ★'d

Where can I item grind so I can upgrade my weapons?

not necessary

youll need a good amount of hp, maybe 6k? when i fought him i had 6.5k. also, it would be a lot easier if your str is 1.2k+ (doesnt have to be but it helps a lot). lionheart's quickstagger helps too

use:

lightning/snow/hope or
lightning/vanille/sazh

mission 7 gives you bomb cores each time gg upgrading item if your broke



refer to my guide
