I feel like I have done enough tests and uploaded too much about him. So this is the last one for now and it is more of a fun discovery.
Remember you can only have the absolute defence buff on one ally and Cor himself? What if you have two Cors?
Turns out you can actually have another set covering your own Cor with another Cor lol. Friend Cor would attack if your Cor initiate an attack, and your Cor would have his own trigger attack as well.
While I don't think it is practical, the wonderful thing about this is that if an enemy is going to use an AoE attack, that means it is for sure targetting all of the targets covered with the two sets of Absolute Defence buff. Both Cor's would actually attack twice, so in total you get 4 attacks in a row triggered by one boss only. If the boss is unlucky enough to get broken and pushed back, it is going to take another 4 attacks in the face lol.
Doubt anyone would utilize this in a serious fight, but it is good to know it actually works nonetheless. Consider this a little fun trivia.
