I have a question for you, if the paladin is the one who applies the established laws and represents them. So what is the Priest?
The answer is easy, it is the one who narrates and makes the laws.
The Priest is nothing more than a monk who apart from following a dogma, repeats it, spreads it and judges those who do not follow them.
*Before continuing, I think there are things we should know about the Priest and how he really is, a priest outside of what we known is not someone quite defenseless, he is someone who leads a lot of life, heals and does not only use cloth armor as is believed. So I think the mace in one hand, like the book in the other must be his main equipment with chain mail on his property*
That's why I think the next 3 specializations of the Priest should be the following.
1- Missionary –Role: Healer Subdps
The dear missionary is the one who repeats the word of his god / religion, the man who exists alone and to speak with those "infidels" or to include new acolytes, conjuring sacred phrases from the heights, powerful words to appease his allies as to inspire them courage, without fearing sometimes to go a little overboard.
Their clothes are simple looms with patterns that represent their god, whether gold, blue, red, orange, or white.
His weapon is going to be the Censer (Idea of my friend Samarck) with a book in the other hand, which he will use to spread, together with his words, blessed smoke that will heal allies.
That's not all because it will have a skill called, sacred mark, with which it will enlarge the Censer making it hit the ground, leaving cracks which in due time will disperse healing smoke together with a sacred explosion which will damage the enemies that are still in that place.
We must not forget his words and books , which will help him bless his allies and spread the wrath of his god in the hearts of enemies , percentage healing a maximum amount of life of allies as well as slowing down enemies for fear or just scaring them.
2- Apostle –Role: Healer
The spreader of god, the one who speaks before everyone and who spreads the word of his deity in the communes and towns, the maximum reminder of the teachings of his religion.
Its only purpose is to spread the word with its relatives and remember, therefore it is not in charge of doing damage at all, but it is in charge of only and exclusively placing shields, healing and buffing allies.
His only and main weapon are the papyri (Books too), with writings as old as his own religion.
These Scrolls wrap around nearby allies, shielding them for 2 seconds, then heal the allies for 50% of the remaining amount of shield.
He chains his allies with his papyrus making them share the life they lose so that after a few seconds he heals them all, distributing the damage without anyone dying and restoring everyone in a large area.
He can also summon divine beings which orbit around his allies, increasing different statistics such as healing them per second.
3- Inquisitor –Role: DPS subhealer.
The inquisitor is basically that orthodox being, even more than any paladin, because these inquisitors regardless of whether something is correct or good, they only follow their dogma and never question it, so much so, that they would be capable of committing suicide if they just broke a rule .
That is why these inquisitors are judges of their "Truth" which they impose on their opponents, they attack with their one-handed maces (one in each hand) using mail as armor, they invoke divine maces which attack enemies while they attack together with other hands which grow from his back.
These attacks in turn heal in a very very small area, which generate a meter that after a while explodes healing allies that are behind.
They burn the ungodly and sinful with their holy fire, dealing area damage to the opponent burning them bit by bit as they slam and slam their mace.
His great and last attack is the sacral torture machine, which is an iron maiden which surrounds the enemy, piercing him and immobilizing him, causing sacred burns such as severe bleeding and even death itself.
