Li Shenron said:[...]I think that the option of casting+moving+touching in the same round, which is a special case allowed by the RAW, should work with Spring Attack. If one would like to read the RAW strictly, probably you're not "using the attack action with a melee weapon", even if you consider the touch a melee weapon, because you're actually using a special version of the "cast a spell" action here. However I think it just makes no sense disallowing it at all.[...]
