hong said:No, a spell "in hand" is considered to be cast already, and can't be counterspelled.
Hm, you have a point. It looks like a ring of counterspells wouldn't work on touch spells, unless the touch occurs as part of the casting action (which is allowed).
This is correct.
The rod wouldn't work either since Harm isn't a single target spell (ala Hold Person), or a ray (like Disintegrate).
Theres no real defense other than SR or an antimagic field. Or being undead.
