Battlerager
fighters gain temporary hit points from hitting with melee and close attacks, "plus any temporary hit points normally granted by the power" (exact words used in the compendium).
The Invigorating
keyword is defined such that when a character trained in endurance hits with an invigorating power, they gain temporary hit points.
So, are the temporary hit points granted by the combination of the invigorating keyword on the power, and the character being skilled in Endurance
"temporary hit points normally granted by the power"?
Best Answer
Yes, Battleragers get to double dip on the invigorating powers.
InvigoratingDDI is defined on p7 of the Martial Power book.
Here is a link to the same question (and some related ones) on the wizards board.
This simple table tells you how many temp hp you receive. (Assuming a Battlerager with Endurance)
Temporary HP do not stack. If you gain THP (Temporary Hit Points) and currently have THP, then retain only the highest number of THP.
