Target: One creature
Effect: You spend a healing surge but regain no hit points. Instead, the target regains hit points as if it had spent a healing surge. You must have at least one healing surge remaining to use this power. (PHB 91)
I see no problem with how it's worded, personally. But then again I'm used to reading things that are not very descriptive. I look at it as being two effects with one conditional statement
You must have at least one healing surge to use this power (conditional)
You spend a healing surge but regain no hit points. (effect)
- Ok, as long as I have a surge left, I reduce my number of healing surges by one.
The target regains hit points as if it had spent a healing surge. (effect)
- Ok, I'm the target, so I therefore gain hit points as if I had spent a healing surge.
Fluff arguments don't sway me, so yes, you can use Lay on Hands on yourself. And I'd allow the
Healing Hands feat to add +CHA even when used on themselves, mostly because I think it's just incorrectly worded in the PHB. But as written, no, the +CHA wouldn't affect a LoH on yourself.
