How do I get tifa's ultimate limit technique.

[boys from the dwarf]

has to be disc 3 and tifa in your party and then you get anote from zangan....more story development.....

theres nearly nothing that can only be aqquired on disk 3.

you can get cids venus gospel spear on disk 2 and tifas limit break and ultimate weapon on disk 2. you can also get vincents death penalty and chaos limit break on disk 2. the only imporant item i can think of that cant be aqquired on disk 2 is clouds ultimate weapon.
