I have come to a realization of just how little the gain from this feature really is.
I have just reached lv 2 enlightenment, spent 6 million Daru, only to receive a meager 70-80 stat point bonus to my character via stat transfer.
Edit I forgot I had to spend an additional 1m daru switching from HP to Physical Attack, and the Blessing counter resets once you "swap" for a new choice. For others, you may spend many millions more daru trying to get the skill you want.
I honestly do not know why it never occurred to me beforehand, nor why I ever took the time to do the math. For 6 million Daru wasted, I am beyond dissatisfied with my decision to use precious daru to increase my character stats. I could have maxed out my troops to my current level, as well was given the other troops a modest boost to their level as well, should I decide to switch for any reason.
I would suggest a much greater bonus to stat conversion, as it just doesn't seem to provide anywhere near the same effect in comparison to just regularly upgrading your troops normally.
for 6m daru, I got roughly 80 stats for my character, if I would have spent that 6m on my troops leveling, that would have been 277 troop stats (Per levels for knight) , multiplied by XXX levels.
For anyone wondering if they should spend their Daru on "Enlightenment", I would strongly suggest maxing out their troop level, as well as saving enough for the next level's upgrade, before spending ANY daru on enlightenment.
