I like it but there are a few problems. Invincible is by far the best status in the game and even the strongest invincible applications only last 2 turns so 4 turns is insane. Also the defence debuff should be at least 6 turns so it outlasts the invincibility and then stays for two more turns. In theory with his qqa chain he could recharge his np before the invinciblitiy ran out and then start the process over again.
