So it tends to be both use of the NIN's personal 'spirit' as it were and elemental involvement.
While I very much like the lore book (I own it) I will admit it is very abridged. Afterall it is a supplement. The best way to get lore resources is honestly to play through the class; or replay it if you have an alt and have the time. There is so much that is not covered in anything more than brevity in the lorebook vs. ingame lore. Talking to NPCs, even minor ones (as one npc goes over the rankings in full) help a lot too.
