Well I am glad you found your build and your happy with it. I am a little surprised you went cleric. Heavy armor will help your AC, and you get a second attack from level one. I guess Mercenaries need clerics too. I am curious about some things.
As the cleric of "mount celestia" is worshiping the angel already or Does the Angel worship a deity under the mountain as well?
If the Angel, what is the story hook for the Angle who is granting cleric abilities to grant warlock abilities to the same creature?
Usually, most Deities make Clerics (the Raven Queen, for example) and Warlocks are generally the result of very powerful underlings (Like the Hexblades the Raven Queen forged). So I am just curious if your throwing that out or if you have a work around, what is it?
If your a Cleric of a Deity and a warlock of its underling, How is your GM taking it? We have seen quite a few GMs ranting about Cleric/Warlock incompatibility due to "serving two masters". Generally if your the warlock first, the Deity is might be protecting you from a bad deal or curse after the fact, but being a Cleric first raises a question of if the Diety is cool with you serving its subordinate. Other argued that the Diety would revoke the cleric powers, however, I can see a "I am placing you under the command of X"
I also understand, since you are just posting this 90 mins before you play and you don't actually have any levels of Warlock yet, you might not have answer hammered out in detail. In that case they are just two points to consider to ensure you have answers and it makes since to you and your GM.
Not, judging your decisions just curious how you and your GM are playing it in light of previous debates.
Yeah I don't feel judged. Happy to describe our story.
Mercenary veteran got less choosy about employers. He was probably LN in outlook. Tormented and broken by a betrayal, he was aided by a fallen angel tethered to the material plane. The angel was a planetar who had been too harsh in carrying out his mission. Until he learns mercy, he is not getting back to seven heavens. However, he does not fully get it and instead seeks redemption through martial and militant good in the world.
He takes on he mercenary who is not unlike him in some ways.
Neither know the goal of those in he seven heavens is to see them both redeemed.
The planetar agrees to help the mercenary learn white magic if he acts as herald and hand of the planetar in the world. Both want revenge on a mutual betrayer.
The planetar is hidden away in a cave with altars and other sacred mystical things where he mercenary is taught.
NOW to your actual question: the mercenary is not an ordained priest but has found that when he prays and uses the lore the planetar provides, he is able to harness white magic in the form of 1st level clerical spells. At 2nd level on, the power will be manifested in warlock levels.
He character wears the symbol of celestia (triangle with line through it). Both the planetar and character seek to do the will of my celestia and some of the divine beings there approve.
However, I see the character as serving a pantheon of lawful good beings and has no patron deity per se. Likewise, his patron does as well. Each is used to help redeem the other. Since the celestial patron can already grant 1st level cleric spells and eventually teach level 9 mystic Arcanum, neither the DM nor myself saw 1st level cleric as anything exceptional or outside of the planetar's power to teach or grant.
In play? It was fabulous. I mostly played a combat worthy cleric who did detect evil, magic and spared the dying.
The best was when I used a silver horn (I am proficient) to announce the coming of alkazid (the angel). I used thaumaturgy to make it boom and have the ground shake! It was a fun moment for the herald of an angry angel!
In short, not too invested in the 1st level of cleric being anything other than part of the celestial pact. There is no jealous God as we see it as well within a patron's abilty to grant as well.
It is allowing me to play a very helpful party member who eventually (with eldritch smite) will be able to unleash some
Powerful angelic rage.
This was the most parsimonious and direct route to what I wanted. I can detect evil and magic and comprehend languages (all by level two) and eventually cast tongues as a high level warlock. If anyone doubts his authenticity, he can cast thaumaturgy and blast with a silver horn.
Other routes were less direct but would have worked. Could have done clerical magic initiate for example. Then would still have needed a feat for armor. The route I took allows for me to take tough to compensate for a lower con and a later ASI in CHR since I had to invest so much in wisdom to go this route. Thought about life cleric, but planetary are "weapons of the gods" so war domain seemed a better fit.
