Question:
Can the priest get more favors?
Probably they will get favors from sovereign levels. Maybe they could have access to a unique church improvement that gives them another favor when built, or how about when they kill one of the SK's lieutenants.
Things to use favors for:
-Summoning a powerful unit. An Angel or Lightbringer or whatever.
Would it be possible to have the summoned hero/avatar/incarntion be based on the intangibles/spellbooks.
The DM/Intangibles could reflect the skills available from the start.
Intangibles, evil
- the summoned unit could have darker skills like Dark Spread, raise skeleton/shadow warg/shadow drake/shadow-undead dragon. mass grave seal, horrible wall (or what the spell is called).
Intangible, brave could be reflected with mass buffs to your army. Ex. +5 att/ +5 ini to all your units, skills like the commander from LH.
Intangibles, good
, mass heal, well spring, crusade etc.
The chosen spell books of the soverign could be reflected by having a +1 or +2 to spells cast in combat, and also provide 1 legendary/rare tactical spell from school of spell books with the most books. Ex. if the soverign had 6 chaos books out of 10 books, a tactical spell could be meteor shower. If there were more summoning books, a legendary spell could be summon clone of the avatar or a storm dragon
(1 use per combat). If there were more "good/life" spell books a legendary tactical spell book could be holy light - healing your units, damaging undead/chaos/twisted enemy units (1 use per combat, casting time 1-2).
I would love to see Torin the Chosen or an avatar of the Great Frog
(flying, jumping attack/charge, ranged tongue attack. stinking mud, poison). To summon the Great Frog you first have to build an altar in the first place before even thinking of using a favor to summon him.
