SGE: hooded figure walking through a warzone, as people get injured around them, they keep walking past, but their nouliths 'automatically' heal up the person who needed the aid. Shielding circles automatically drawn around allies before hits can make contact, and when a big attack is about to hit the hooded figure, they don't even flinch. If you remember in ARR's cutscene, a magitek reaper is about to fire, until the BLM lights it up with a massive fire blast. So imagine, that reaper fires, and when the cloud of smoke dissipates, you just see the hooded figure still walking towards whatever they're walking towards, with the nouliths projecting the square shield Alph used in one of the final cutscenes when a planet was being thrown at him. Essentially, I figure something like
this, but with nouliths instead of feathers
