Yeah, I hate that DnD is such a resource management game too. (More so that is is the ONLY game my group will consider playing.)
I tend to horde any limited resource. TTRPG or video game.
Is this group of mooks big enough to justify using power/spell/item X? Is there a bigger group around the corner? Is this just a lieutenant or the BBEG? Oh, this guy is monologueing, he must be the BBEG. But does his fight have multiple phases? OR is he just a puppet and the real BBEG is waiting for us to blow all our abilities.
Doesn’t matter how narratively I’m engaged in the plot. I’ve got a tactically aware mind and these thoughts are always there.
I had a similar idea for a wholesome Celestial Warlock recently. Remembering a bit form some stand-up comedian in the 90s; with schizophrenics, why do the voices always tell them to do bad things?
Character is an low-key Aasimar, but tries to hid it by being all goth. They were mostly ignored by their family, like 90a latch-key kid.
They try to act all dark and edgy, but they constantly have their bright and chipper Celestial patron whispering in their ear to do positive things. Played like the Bowler and her dad in Mystery Men.
“You should really help that orphan find their real parents.” “You HAVE to rescue the princess!” “Hey, help that old lady across the street.” “You don’t need all their gold as a reward, you should leave them at least half.” “Hey. Hey! Tell [party’s druid] that she really looks cute in that outfit.”
Could also work with Divine Soul Sorcerer, with their angelic ancestor whispering in their ear.
