Metamagic feat 'reach spell' Complete Divine p. 84.
Metamagic feat that turns a touch spell into a ray-spell with a range of 30 ft. "The spell effectivly becomes a ray, so you must succeed on a ranged touch attack to bestow the spell upon the recipient." +2 spell levels
Metamagic feat 'chain spell' Complete Arcane p. 76.
Metamagic feat that allows you to 'chain' a spell that is not a touch spell, so that it affects more targets than one, giving the primary target fulle effect and secondary targets half effect. "Any spell that specifies a single target and have a range greater than touch can be chained." +3 spell levels
Can a touch spell, metamagiced with reach spell - to turn it into a ray, in its turn be metamagiced into a chained spell as the spell with reach applied is not a touch spell. Let's say a Cure light/medium/serious wounds. Of course with the +5 spell level price (or turning attempts if both are divine metamagiced) and all.
