Familiars and Share Spells?

[DarkJester]

What happens when you share a spell that can be discharged with your familiar? For instance, if you share protection from energy, which discharges when it receives X damage. Is the spell treated as two separate spells for dispelling and keeping track of how much remains before the spell is discharged, or is it treated as a single spell?

It is the same spell so it would be treated as a single spell.

Share Spells
At the master’s option, he may have any spell (but not any spell-like ability) he casts on himself also affect his familiar. The familiar must be within 5 feet at the time of casting to receive the benefit.

If the spell or effect has a duration other than instantaneous, it stops affecting the familiar if it moves farther than 5 feet away and will not affect the familiar again even if it returns to the master before the duration expires. Additionally, the master may cast a spell with a target of "You" on his familiar (as a touch range spell) instead of on himself.

A master and his familiar can share spells even if the spells normally do not affect creatures of the familiar’s type (magical beast).

Protection from Energy
Abjuration
Level: Clr 3, Drd 3, Luck 3, Protection 3, Rgr 2, Sor/Wiz 3
Components: V, S, DF
Casting Time: 1 standard action
Range: Touch
Target: Creature touched
Duration: 10 min./level or until discharged
Saving Throw: Fortitude negates (harmless)
Spell Resistance: Yes (harmless)

Protection from energy grants temporary immunity to the type of energy you specify when you cast it (acid, cold, electricity, fire, or sonic). When the spell absorbs 12 points per caster level of energy damage (to a maximum of 120 points at 10th level), it is discharged.

Note: Protection from energy overlaps (and does not stack with) resist energy. If a character is warded by protection from energy and resist energy, the protection spell absorbs damage until its power is exhausted.

What if the spell grants you a bonus? For instance, False Life.

False Life
Necromancy
Level: Sor/Wiz 2
Components: V, S, M
Casting Time: 1 standard action
Range: Personal
Target: You
Duration: 1 hour/level or until discharged; see text

You harness the power of unlife to grant yourself a limited ability to avoid death. While this spell is in effect, you gain temporary hit points equal to 1d10 +1 per caster level (maximum +10).

It's considered as if the spell were cast seperately on the caster and the familiar with any random effects rolled once. False Life will give each the same number but damage done to one of them won't effect the HP remaining on the other.
