Assassin Champion?
I have in mind an assassin drow because one of my OC’s in any rpg is an assassin dark elf.
i learned decently quickly in what i’d now call a “test run” that a pure rogue is pretty underpowered, especially considering that i like to play the backstabby type assassin rather than a stealth archer.
i was thinking that if i added champion fighter to the mix i could get an extra attack, crit-chance increase, fighting style (either duelling or two weapon. could do archery for situational use then wear bracers that give two weapon), and action surge to really even her out with other damage riders.
a 6 rogue 6 fighter split would gain what i said before on top of uncanny, expertise, and decent sneak attack damage, while retaining three feats (namely actor for charisma and more expertise, savage attacker, & ASI).
in my mind this is a healthy mix with 6 skills with expertise, and good damage potential making her fare well both in & out of combat.
i could however do 7 rogue 5 fighter. dropping one feat for one more d6 in sneak attack, adding evasion, and keeping extra attack.
this would make her slightly less of a skill monkey (and i do think actor adds good rp flavor to her skillset) but more martially adept.
if needed my stat spread at game-start is:
STR-10
DEX-17 (22 by end game with hags hair, ASI, and mirror)
CON-14
INT-8 (unfortunate dump stat but durge doesn’t need int)
WIS-12
CHA-14 (possible 16 by end game with actor and mirror if lucky)
bonus suggestion: i could just go pure gloomstalker, as i get most of what i want anyway (extra attack, dread ambusher & hunter’s mark to supplement sneak attack, fighting style, etc. etc.) while also getting some magic, however i am a bit iffy on that because at the end of the day she wouldn’t be a backstabby assassin she’d be a more martial hunter-type with some magic
