To track inventory of my PC's, I create boxes on the paper, then assign location with the following basic nomenclature;
On Belt:
Pouch #1, Pouch #2, (Pouches can hold up to 3lbs of material), scabbard, knife, etc.
Large Purse under arm(likie a saddle bag on the hip, holds up to 10 lbs)
Large Purse on hip (normally it's one or the other with carried purse/saddle bags)
On Back: quiver, bow, scabbard, etc
Ruck sack (if carried)
Back pack (inside)
Back Pack (outside)
Pockets (note, I ofetn dont have this as most middle age style clothing did not have them).
Horse: saddle, rope, two sacks, bedroll, tard, four water skins, etc.
Sacks: 17 dats preserved provisions (2lbs a day), flint and steel, four wolf furs, tannong kit)
I have created a seperate listing for quiver when called for, as when the quiver held 12 different wands instead of arrows. A scroll case is either on the hip, slung over the back, or carried in robes. Each case should list what scrolls are them. Accessing them is a simple shifting item action, requiring 20% activity. I see superior scroll cases that reduce shift time to 10%, but few have ever bought them (instead waiting to take them from dead enemy spell users
)
