Feel free to point out other spells that are not castable by us.
I'm still wondering why we don't have Diaga II yet. Also, poison III would help a lot on kite strategies. Curse and Virus would be nice, but SE would probably make the vast majority of the NM's immune to those since they would be too easy to defeat otherwise. Can you imagine sticking curse on let's say... Pil? >=)
