For me, this is why Valor Bard/Blade Pact Warlock is a three-cheese club sandwich. They're both Cah powered and Bards 'know' their spells - so they can heal, blast AND wail with a Pact Blade.
since clerics prepare their list of available spells during a long rest, and since they are allowed to use warlock slot levels to determine maximum spell level known, even a 1st level cleric max level warlock has access to all of the cleric spells, just not at the same time. Each long rest, they have access to wis mod+cleric level spells <=spell slot level.
so, my interpretation is that an Mc cleric/warlock, can only pull from cleric or warlock spell lists, can only prepare the list of known spells based on their class level respectively, and then they look at highest slot level to determine which level of spells they know. clerics reset during long rest, warlocks do not.
Why not just have levels stack for "extra attack" and "stat increase"?
Im also of dipping into a bit of cleric levels in my warlock's later levels my only problemis tha pairing of my patron and diety that wont be thematically oposing. Any dieties that i can pair up with a Fiend patron?
i agree that Life domain diety and a Fiend patron can be a bit of a stretch...
Remember that your patron for warlock doesn't have to be willing. They show an example of being born a descendant of a warlock who made the deal. They give you powers and are trying to "steal your soul" in that sense but you can still be good and fighting it. Perhaps you're a cleric and that god is your savior but it's a wrest for final control of where your soul goes, etc. They made it that way so that you can really use any deity and still be a warlock if you play it that weay. Obviously some people will want to do it a certain way but they wrote a book about the one tiefling warlock to show this off.
