At the cost of almost all your mana for a very little heal.

Depends on how many enemies are around you.

At level 60 you can have some solo fun running through Haukke HM pulling the entire large groups and sustaining yourself both mp and hp with only BP+DA+AD. Probably other ones too, just that is the only one I tried lol for the lulz.
