I am trying to rework Path of the Killer in a more realistic and less immersion-breaking direction, and I would love to see if someone has worked on it for their own campaign and share ideas. Rank 1 is very much in tone, but Rank 2 and 3 veer into ACME antics and do not support the fantasy of the silent assassin in the shadows. I am still new to the game and would love to learn from other people's more polished rules and mechanics, if possible.
The way I see it, Rank 2 and 3 can be about hiding in shadows, fast movement to get to the target, distracting to open up vulnerable back for a big surprising strike with a chance to kill outright. I would love to stay true to Reforged Power as well, where Rank 4 and 5 are about the politics of an assassin and the ability to research your victim.
