I have found myself in an argument with a friend of mine over specifics here. He claims that any healing, such as from a wand of CLW should grant THP if used on the PEP, and thus add THP towards the boom-total. The written rules do not support this, but he claims that it has to work because CLW derives its healing from the PEP, and so is subject to the same rules.
This is, to me, a pretty obvious case of personal interpretation of how the rules "should" work over RAW (maybe a case of RAI, I dunno), but can I get some source or support one way or the other?
