@Kakost I just checked Summon Bear. Summoner3 does not raise it to lvl 13. You get a useless lvl 10 bear for that skill point. I recemmend to stay with elemental scrolls with Battle Prayer as alternate summons.
This seems like a very low level(useless) ability considering you need such a high Rep (thus higher skill lvl) with Varannari to acquire it.
Well, that's a bummer. Oh well.
Phew! Im so busy lately that I havent been able to touch the game so far. A pity, but I dont know when or even if I'll ever be able to finish this diary.
But, I'd say it is already a huge success. I can see that B.Prayer AND Flames of Faith are fully usable for it, and with high Per (even at the low level of 14 is already 5, +1 from item which will be +2 with Bishop Ring) and moderately high Int (it's 3 or 4 already, and there's no reason not to have it at 4 in order to increase the mana pool, and there are late game items that give +2, for a total of 6), and considering how mid mana potions costs mere pennies at late game, Im 100% sure that the Shaman (Summoner Cleric) can use Wolf, B.Prayer and FoF, as well as Heal 3 and Intervention 3, strengthened with Summoner 3, without any concerns about mana, and having all those skills maxed at lvl 21 which, all things considered, it is still "early late game", so there's plenty of stuff to enjoy this build to its fullest (not just Ark, but the witches groove, the pit, Sunken Citatel and many many more), and there's still room to add something extra with those skill points from lvls 22 to 25, not even taking into consideration the extra skill points from the SoH.
And in terms of traits, there's even room to improve a bit of fighting skills if wanted, adding some Str (or Agi) to imcrease a bit of damage and whatnot, since it's not really necessary to put so much into Per or Int (like it is for a Mage for example).
I havent really gave it all that much thought about it, but it is possible to add something damage skills, or maybe defensive ones (B.Development may be an option). Those options can be taken into consideration, or just keep increasing some more "divine mojo" magics, I don't know.
Therefore, pretty solid build, super approved, super fun (a lot more than I was expecting).
I think the Summoner Cleric does indeed deserves it's own space rather than being just a simple variation over the Church of the Three spellcaster. It's a fantastic and memorable game experience, I fully recommend.
And as for your initial thoughts, Im pretty confident that Flames of Faith is a superb addition to it.
