UPDATE:
After some thought and deliberation it has been pointed out to me that a special ability-magic attribute should be included with SOLDIERS, this will start out as a low-tier specialty that is linked to the chosen Aeon, it can consist of offensive, defensive, or some other purpose that assists the SOLIDER in and, or, out of battle. Originally it was going to be included in the skill set, however the skill sets are designated for attributes that exist for the character as a whole and are not related to the Aeon. So I'm going to be updating the section of the codex on SOLIDER and update the CS accordingly.
It'll be labeled as a special ability, that relates to "magic", but it is not to be treated as a spell, or some such.
I don't have an example prepared, however, I trust everyone's creativity.
Keep in mind that powers and abilities also progress and grow with the plot and that this special ability is different from the Limit/Overdrive, as it can be used with more consistency than the last resort power.
