the healing is being dropped so a few changes should be done to other parts of the PoH spell
1. Mana cost dropped OR
2. Cast time lowered OR
3. Turn PoH into a casted version of CoH
1. looks like this would be the easiest to do and can be a bone
2. with 3xstack serendipity you would want to make sure the lowered cast time does not make the spell OP
3. (my personal choice) may make PoH OP not shure
