Cure at lv1 to cure debuffs. Deprotected Zone is kinda bad, most leave it at lv0 (or lv1 if going Plague Doctor)… but since you’re a SPR build it’ll lower a good amount of defense, making it decent for bossing. Get it to at least lv1, if you don’t have more points for it then lv1 is fine, otherwise dump leftover points there after Safety Zone.
(You don’t really need max Safety Zone if you’re going for at least Cleric C2, as that gives you access to an attribute increasing the number of blocks by a max of 20. Just leave the leftover points there, lv3~5 is fine. In a SPR build you’ll have room to max it in C2 though, since you won’t be leveling Cure too much.)
Full SPR Support normally goes Cleric2>Priest3, due to Stoneskin scaling with SPR, and possibly Blessing if we get the KR patch that makes it scale with SPR (and absurdly well so). Other than that, you have a few options between Oracle1, Plague Doctor, Kabbalist, Dievbirdys/Krivis1, or Pardoner (probably not ideal).
Cleric C3 is an option for GvG, but doesn’t add much otherwise.
and yes, you’ll need a few points into CON. Just add as you see fit until 80 (80 points shown, not 80 points invested) or so. INT is unnecessary though, the only uses for it in an FS build are
- leveling faster and
- stronger heals.
Number 1 is a sacrifice all FSs have to make however, and for #2 you can buff your Heal tiles with Restoration scrolls (cheap), and Mass Heal scales equally with both SPR and INT anyway.
