So, I'm brand new to Call of Cthulhu (though I did read through summaries of Lovecraft's Source Material), and so are my players.
Not knowing anything and wanting to be careful, I gave the party of 7 a total of 80yrd of Gauze Bandage, as well as 8 pints of Rubbing Alcohol, just in case that was required for wound care.
However, now I find myself asking: How much Gauze and Rubbing Alcohol would taking care of a wound take? Whether that be First Aid or just general wound care after the immediate danger has passed.
