if we have to choose which traits we want to discuss. I am going to list some that could be home brewed into 5.0 fairly easily from 3.5. Most of the 'arche-type feats' could be offered to players as a choice of feat for lvl 1, as they only effect how NPCs treat you in the get go. These could be enough to create an illusion of choice without causing someone to panic.
1) Anti-hero: Your posture gives of a frightening aura, you get -1 roll with scholars, nobles, and lawful checks. Gain +1 in intimidation, survival, and acrobatics
2) doctor: Your posture radiates a calming aura: -1 with deception, sleight of hand, and intimidation checks. Gain +1 with religion, persuasion, and Arcana
3) Magician: you gain +1 in insight, performance, and investigation checks. -1 for persuasion, athletics, and acrobatics.
4) Outcast: you gain +1 in animal handling, medicine and slight of hand. -1 for history, religion, and persuasion.
5) Pretty Boy / Girl: +1 in stealth, +1 in insight, +1 in persuasion. -1 for history, investigation, and athletics.
In addition Larian can add the following feats at lvl 1 from Racials, if the player chooses them over a stat increase:
1) Dragonborn: enhanced scent: you are able to see anyone invisible if they are within 4 cells
2) dwarf: extended burst: able to use a bonus action after using dash
3) elf: Elven Archery: roll a 1d20 to avoid 1 arrow per long rest
4) Gnome / half-ling: Nut Cracker: [bonus action] roll a 1d4 to knock an enemy prone if male, a 1d20 against females
5) half elf: gain +1 with bow and daggers
6) tiefling: tail slam: use your tail to attempt to unbalance [roll a 1d20] [[bonus action]
7) Drow: spellweb: create difficult terrain in a 1 by 1 cell cone
The above is just me spit-balling, but its an idea to keep the discussion moving forward.
