Don't spend LP on gambit slots: Get 3 or 4 for each player than wait till you get to Archades or Balfonheim where you can buy all the gambit conditions.

Same for those "Maximize HP while barehanded" (or "max HP"). Are you kidding me ? When would I leave a character barehanded ? Weapons don't even get damaged on XII. Same for Max HP, after the first hit to your guy it is useless.

Augments, then magick, then techniques. Use LP for accessories, weapons and armor when you buy them
