Hey folks!
I've recently found myself interested in converting some of Starfinder content - namely classes - to Pathfinder 2e. I was in two minds about where to post it - here or in conversions, but due to the reasons described below I chose the homebrew subforum. And so I'd like to present you my idea of a Vanguard - a chaotic Champion who uses the power of entropy to protect themselves and harm their enemies. It's mostly built around existing mechanics that fit the base class and numberic values used in other abilities that I usually keep in mind while designing homebrews.
Disclaimer: I do know that base Vanguard mechanics in Starfinder have nothing to do with worshiping gods and there aren't any alignment restrictions, so it is by no means a direct conversion of each an every ability - more like a Vanguard-inspired Champion cause that could both give one the feeling of the original class and fit Pathfinder 2e mechanically without breaking anything. It does not rely on any other homebrew elements and is fully compatible with base PF2e rules.
So, without further ado - meet the Vanguard. And do not hesitate to share your opinion in comments below and/or ask questions, if clarification on certain mechanics is needed!
