SP for Healers
Beyond using the Tempest Trials for grinding, what is the ideal strategy for getting a lot of SP for Healers? (may confer blessing if necessary)
A decent way is to do chip damage and hole up in a corner with three super tanky units (without weapons, so they can't kill) If the healer has Pain or if you have the Savage Blow sacred seal you can chip the enemies down so a healer without Wrathful Staff can still get kills.
This is my strategy for levelling up any unit, really, since a Fort Def - Atk Pain+++ Azama is absolutely amazing for getting any unit down low enough for any unit to kill. (Except in the case of TA or TA weapons, but even then sometimes.)
they can manage in the magic training map because all the enemies have dirt poor res.
what i used to do is i have a ranged unit with Fury tanking melee hits from a unit that is like lvl 1 and i just spam healing. this would be good enough to get them up a few levels at first and then you'll probably have a decent boost to your attack stat to start finishing off enemies. most healers will do 1 damage or more without wrathful staff so if you got fallen takumi, his skadi is great for chip damage when training
The answers above seem fine to me; I like to bring a healer in chain challenges so of you do that during weekends and spam heal (wisely - save an imbue for a turn if it's necessary) every chance you get (and jump in for an occasional KO), you can sometimes accumulate 100+ SP per chain challenge.
