Actually outside cura IIis a great MP saver if you have misery up and fighting something that does alot of aoeing,. i seen good results from it, of course it is situational but it defintly has good uses in the hands of smart whms.
Regen 4This is almost exactly the same as astral favor using carby. While regen effects look good on paper, they rarely get used because they're not potent enough
Restores 30HP/tick for 20 ticks, or 600 HP healed over 60 seconds.
Cleric's Briault increases the HP healed per tick by 4.
Merits can boost this effect further (+1 to +5)
Does not work with the SCH Stratagem Accession.
Orison Mitts +1/Orison Mitts +2 Increases duration of the Regen family by 10/15 seconds.
Cleric's Briault + Orison Mitts +2 + max merits = 39HP/tick for a maximum of 975 HP over 75 seconds
Regen 3 (since it can be aoed unlike 4)
Restores 20HP/tick for 20 ticks, or 400 HP healed over 60 seconds.
Cleric's Briault increases the HP healed per tick by 3.
Merits can boost this effect further (+1 to +5)
Cleric's Briault + max merits = 28HP/tick for a maximum of 560 HP.
In short regen should never be underestimated if used in the right situations. i shake my head at whms who never use it saying it's "not worth it"
