Just checked in iTOS to see if Praktiri and Ein Sof healing attribute stacks and…
It stacks! It even heals more than 2x the amount, for a total of 34,6% of your max HP. That alone is damn worth the investment of 2 Ranks into Sadhu on my Kabbalist in the future (when I’ve gotten rid of Sadhu C3 xD).
Also, if the Healing attribute “Heal: Creating Extra” is ever going to work, that’s another 22% HP recovered when casting Heal at a certain chance xD
Since ASPD influences OOB now, it’s pretty much a practical choice, because you can autoattack monsters with higher mdef and OOB them if they have higher def. Now we need a stack of OOB attacks with the Clerics Blunt weapon stun attribute and all is good for the autoattack beast
