For those who don't know - respec stands for respecialization.
<br />
<br />It allows you to change the stats/skills/proficencies of your character or NPC.
<br />
<br />You access it from the camp menu and it will be pretty self-explanatory after that.
<br />
<br />I have included an extra command where you may also respec your non-hero troops as well, but beware if you do that it will probably respec every troop of that type in the game(!).
