Correction to above:
If you are trained in Endurance, and you -hit- with an attack from an Invigorating power, you gain temporary hps equal to your con mod. You can only gain temphps from an Invigorating power once per turn, regardless of how many times you may hit with that power. No, this has nothing to do with stacking rules for temp-hp, and no, battlerager vigor does not allow you to work around this.
No, because you never get them.
PHBII p 220:
Invigorating
If you are trained in Endurance, you gain temporary
hit points equal to your Constitution modifier when
you hit with a power that has the invigorating keyword.
No invigorating power grants temporary hit
points more than once during a turn, even if you hit
more than once with that power.
If the power never grants the hit points, you have nothing to stack. Thank you.
I assure you, I am not misreading the text.
My statement, which you have disputed, was that an Invigorating power only gives you temporary hps once, and that has nothing to do with the rules for stacking temporary hit points. You disputed that, saying it does. I pointed out the rule that explicitly states my point. You are now mentioning an irrelevant case.
Ok, I think we have a language misunderstanding
I wasn't disputing what you said now. I was disputing that invigorating has nothing to do with stacking of temporary HP. I thought it was that that you were saying.
So basically we were talking about different things.
