So I was looking at the "Elven Spell Lore" feat just now, and I noticed the part about changing the energy type of a single damaging spell chosen when you pick the feat.
The feat itself doesn't give a list of types of energy damage, like most arcane feats which list the standard "Fire, Cold, Sonic, Acid, Electricity". This means we can pick "Positive Energy" right? Need some healing? A "Positiveball" should work out just fine? Am I reading this wrong?
