in reference to below poster being unsure what line of heals this spell is part of, - as can be seen by the name it is in the "light" series, not the "remedy" series.
the cast time is likewise 3.75 compared to supernal remedy at 1.75. not sure where the blur comes in.
in reference to those complaining of the "high mana cost" - the prior spell in this series was "ethereal light" which had a mana/heal ratio of 4.08. at level 63, this spell has a ratio of 4.55 which increases to 4.58 at 65. quite an improvement.
in comparison, supernal remedy has a 3.625 mana/heal ratio.
this spell is a very nice upgrade to the "light" series of heals, and with a beneficial haste of 15% and blessing of reverence- the cast time is only 2.8, which is just 1 second longer than supernal remedy (which remains unchanged by foci or effects)
