Hi all!

I'm new to DnD 5e and could use your help on the Shadowheart build. I'm going to pick her as PC for my first playthrough (saving a custom character build for a later run). Instead of playing a dark support cleric, I want to make her a high initiative, mobile, sneaky melee damage dealer, who can take out the most annoying enemy quickly. Still very thematic for her I think.

1 lvl or more (how many?) of Cleric of Shar should be part of the build for story reasons. But is the thievery domain still the way to go?

After that it gets complicated: multiclassing into thief, assasin, shadow monk, gloom stalker? All seems fitting. Dips into fighter even for more attacks per round?

My initial idea was multiclassing into shadow monk, because of, well, the name and play style and because cleric and monk are both wisdom based classes. Surely there are other/better class synergies that I don't see?

Looking for a robust, proven build path that keeps me from respecing through the available options and let's me focus on the game instead.

Cheers!
