Needed a small smoke break mid-train robbery

is there like an addiction and withdrawal mechanic in rdr2m

No

But when your tuberculosis starts getting serious, smoking causes Arthur to start coughing violently

so then what does smoking do that's good?
Is it required at parts of the game? Does it just look cool??

Smoking fills up your stamina and deadeye cores (and slightly decreases your health core)

Ah
What is a deadeye core
what is a core

this guy

ohhh rigghhtt of couurrsssee

😭

no wait it's this

Cores are attributes that fill up their respective bars when they're low, you can eat, drink, and smoke to fill them up

Health core heals you when you have low health

Stamina core regenerates your stamina

Deadeye core lets you use deadeye (this is deadeye, basically bullet time) 8s4gpt.gif (click to show)

I smoked because my deadeye core was empty

Ahhh
