I've just had an error in the description of 1st level Arcane Spell "Pep" pointed out to me. The description is missing a sentence: "Can only affect a given target once per day."
Pep is supposed to be a spell version of the "second wind" optional rule, not the endless supply of hit points the incomplete description currently in the rules turns it into. Apologies for not catching this major error. Thanks and a tip of the GM Hat to Eponymous for bringing it to my attention.
