What on earth were the designers smoking when they made this spell?
Why would I ever want to ever play a Paladin again, ever, when I could just play a class that is a MUCH better healer, much better combat buffer, and can situationally gain all the important parts of the Paladin class for the moments when I need it?
I just don't... I can't... I mean... what?
13 rounds is more than I need. It is not like a well-made battle cleric or oracle can't already put out good numbers.
Wait, it's touch so now I get to hand it over to the fighter or barbarian who is already raging, or anyone else.
I did notice the paladin level was only for 1/2 my level, but +7 to damage even at that level is not a small thing, and it is not like I could not make scrolls of it.
There are different spells, but not ones that power up a character in this particular manner.
I could just counter the spell with DR, but that defeats the point of it being cast.
Of course someone might say if the player does not know you fudged extra hp or DR and he had fun that is all that matters. Others will say you should have ban the spell up front instead of having players waste actions
ect..other arguments follow that are playstyle dependent.
My personal rule is that if I can't do it to the players they can't do it to the NPC's. Well there are exceptions for really cool ideas.
