Under the Treat Injury skill:
"Long-term care, restoring hit points, treating disease, treating poison, or stabilizing a dying character requires a medical kit. Reviving a dazed, stunned, or unconscious character requires either a first aid kit or a medical kit. Surgery requires a surgery kit. If the character does not have the appropriate kit, he or she takes a -4 penalty on the check."
Double checking just to be sure, I still can take the -4 penalty yes?
