Would Close Range Magus Arcana allow me to hold the charge on a ranged touch attack I choose to cast as a melee touch thanks to Close Range? Example I cast scorching ray (ranged touch normally) as a melee touch and miss, am I able to use it again since its a melee touch that I can hold the charge for?
I dont see why not. They are 'delivered as melee touch attack spells' so the 'charge' will be held until you do hit, iirc.
