1st aide gloves come from the the Pathfinder society primer page 24
The nice thing about these gloves is you do not have to make a use magic device roll to use the gloves.
The wearer as a standard action can cast any of the spells by permanently expending a number of sapphires equal to the spell level.
The way it is phrased any player class can use the gloves.
1. If you have an improved familiar with hands that uses wands can the familiar use 1st aide gloves?
2. If you have cast breath of live on your left hand glove and still have sapphires on your right can you spend partial money to replenish your left hands sapphires?
3. can you use breath of life on yourself if you are wearing the gloves when you die?
4. if you are wearing the gloves and die would another player be able to take off your gloves and use them in time to give you the breath of life in time?
5. if there are more limits put on familiars or animal companions using magic please send me a link.
