I can resort to 5e (either reputable homebrew or base game archetypes) to fulfill any fantasies if it be necessary but I was actually planning something like arachno monk plus throwing ace rogue. I also have purple martins complete version o adventurers resources(or something like that) an the spy style monk subclass seems like a good fit. While doing that tho I dont want to cram in too many similarities given that going rogue at 1st basically makes the rogue variant monk kinda redundant.Another thing to keep in mind when using synergy feats such as the Nightstalker are which archetypes of the Rogue and the Adept you want to use here. Currently the Adept has 11 archetypes, and the Rogue has 10 archetypes listed on the A5e Tools website. Getting the right pair of Adept/Rogue archetypes to work together is going to be tricky for the Nightstalker. Do you have any favorite archetypes from either class?
