Page 478 of the core rulebook states:

A typical potion or oil consists of 1 ounce of liquid held in a ceramic or glass vial fitted with a tight stopper. The stoppered container is usually no more than 1 inch wide and 2 inches high. The vial has AC 13, 1 hit point, hardness 1, and a break DC of 12.

But is this true no matter who is holding it, regardless of any Dexterity modifier or Dodge bonus?


Ugh, found my own answer on page 460.

Yes, include dexterity modifier if being held by a creature. From that page, emphasis mine:

General descriptions include notes on activation, random generation, and other material. The AC, hardness, hit points, and break DC are given for typical examples of some magic items. The AC assumes that the item is unattended and includes a –5 penalty for the item’s effective Dexterity of 0. If a creature holds the item, use the creature’s Dexterity modifier in place of the –5 penalty.

  • \$\begingroup\$ Note that means that a potion vial held by someone with a 10 (+0) Dexterity is 18, not 13. That's a pretty huge difference. \$\endgroup\$ Mar 13 '15 at 5:02

    \$\begingroup\$ And, oddly, that a stationary, unattended vial is actually AC 15 ("An object's Armor Class is equal to 10 + its size modifier... + its Dexterity modifier. An inanimate object has not only a Dexterity of 0 (−5 penalty to AC), but also an additional −2 penalty to its AC"). I don't know when the typical unattended vial's AC would ever actually be 13. \$\endgroup\$ Mar 13 '15 at 9:03

    \$\begingroup\$ @Heyicanchan Wouldn't that be AC 11? 10 + 8 size -5 dex -2 inanimate. It looks like whoever wrote up the potion vial missed the extra -2 penalty. \$\endgroup\$ Mar 13 '15 at 10:09
  • \$\begingroup\$ @Weaveworker89 Whatever it is, it for sure ain't 13. :-) \$\endgroup\$ Mar 13 '15 at 10:38
