This is my final improved auto strategy for Trial of Reckoning hard boss Yunalesca.
I finally maxed out my characters and now I can show the details of my setup that allows me to get over 8k almost every try on auto.
My espers are all with maximum atk / slash atk / element atk / wind eater possible.
I have maximum affinity between all of the units and resonance with all espers I use.
My current record is 10200+ pts on manual and I will be posting a video to show how I've done it.
