yeah. on my first playthrough i had to fight weiss with a level 3 rifle (or the one above that) because i had no ammo for anything else.

anyway. how are you doing?

i'd suggest investing in the accessory that increase physical damage and also have a blizzard materia and buy the two items that raise the magics power.

because the second part of the azul battle is hard. you can only damage him with magic and physical attacks by if you have a blizzard materia on full power (level 3. it starts on level one and each of them items raises it by one.) if you dont have the materia floater and the other one, just buy them. there 1000gil each.

if you have a lot of ethers you should be able to nearly kill him or kill him just by using magic.
