You can scavenge for proper medical supplies in any urban or natural setting.
Prerequisite: Heal 1 rank.
BENEFIT
When attempting a Heal check that usually requires a healer’s kit, you don’t take a penalty on the check for not having a healer’s kit. When you use a healer’s kit, you can augment it with improvised supplies, gaining an additional +2 circumstance bonus on your check.
Finally, you can treat any Cure Potion, Hi-Potion, or X-Potion you drink yourself or administer to another character as though its caster level were equal to the number of ranks you have in the Heal skill. The spell’s normal limitations apply; for example, a Cure Potion can cure a maximum of 1d6+5 points of damage, even if you have more than 5 ranks in the Heal skill. Hi-Potion‘s max is 3d6+11, X-Potion‘s max is 5d6+16.
