150 * (1 + Empower heal (50% or 0.5) + Devotion (at least a 102 item to get 51% so 0.51) + Life magic II (20% or 0.2))
That is how it works. And that amounts to 150*2.21 = 331 before healing amplification.
The fact that someone can 'forget' that maximize and empower do not work on heal spells shows that someone never played a divine character or is intentionally trying to spread misinformation.
I am posting again because the amount of incorrect data is becoming ridiculous.
And we can see what happens if posters like Chai and Shade are left without correcting them at every step.
