How do temporary hitpoints stack?

[DiscOH]

I can't find anything about how temporary hitpoints stack in any pathfinder materials. This leads me only to assume they can (which is broken). An oracle of life is using valor and life link to give permanent health points at will in one of my games.

I like to play things RAW rather than banning whatever I feel is too strong, so are there any actual rules that say this shouldn't happen?

Temporary hit points generally don't stack if they are from the same source, they overlap (so only the largest amount applies)

From 3.5 FAQ, Pathfinder hasn't addressed this yet in FAQ to my knowledge.:

"Temporary hit points gained from multiple applications of the same effect don’t stack. Instead, the highest number of temporary hit points gained from that effect apply. If temporary hit points are gained from multiple, different sources that stack, keep track of those sources and when they were gained separately. Any damage taken is first subtracted from the oldest effect that granted temporary hit points. When those are gone, subtract damage from the next oldest effect, and so on."

Life link doesn't give temporary hit points

life link:

Life Link (Su): As a standard action, you may create a bond between yourself and another creature. Each round at the start of your turn, if the bonded creature is wounded for 5 or more hit points below its maximum hit points, it heals 5 hit points and you take 5 hit points of damage. You may have one bond active per oracle level. This bond continues until the bonded creature dies, you die, the distance between you and the other creature exceeds medium range, or you end it as an immediate action (if you have multiple bonds active, you may end as many as you want as part of the same immediate action).

What is the "Valor" that the Oracle is using, if it is the only source of temporary hit points, it should work with Life Link.

I'm sorry, the spell name is virtue.

0 level spell, 1 THP.

So, since 3.5 and pathfinder have a different core rulebook, there is no reason to assume the 3.5 ruling is binding for pathfinder, right?

[Stome]

No it does not work. Even without the 3.5 FAQ general stacking rules still apply. The same effect from the same spell never stack.

[DiscOH]

Awesome, I double checked the stacking rules and, as you said, it seems to prevent THP abuse pretty well.

Thanks.
