I am also a GM (Basic & Forgotten Realms since 1979 - now almost exclusively in Eberron) so I understand your idea about the use of feats affecting spells. Since the v3.5 rules came out I have looked at the range attack feats for this exact reason. In my campaign, i have a "house rule" which my players accepted with almost no disagreement. The Weapon Focus feat does say it can apply to 'Rays' and if you look in the Complete Arcane at the Range Spell Specialization which lists as a prerequisite 'Range Spell Focus' (not Weapon Focus - Ray Spells), I decided that the Range Attack Feats which are normally used for mundane range weapons can be used for ranged attack & ranged touch attack spells, as long as the caster takes the "Weapon Focus-Ranged Spell" feat. this is different from the Player Handbook feat and I can only find it mentioned in the Arcane feat mentioned above, but it seems like a fair way to allow the use but with a higher cost to offset the extra bonus. Just like the flaws usage, I feel that all 'additional' benefits need to be balanced by a 'cost'. Hope this helps...

Can the "point blank shot" feat tree be used to enhance magical ray attacks? The PHB specifically states that Weapon Focus can be used with "ray," but does not mention whether Point Blank Shot, Far Shot, Precise Shot, etc. work with magical ray attacks. DM argued against--but I'm not certain I agree. DM feels ranged touch attacks are already easy enough and don't need feats to boost accuracy. (Far Shot may be problematic because ranged touch attacks don't have range increments, and multishot is obviously problematic for everything besides regular bows (plus IIRC there's a feat somewhere for splitting rays). However, I don't see any reason why a spellcaster couldn't practice enough to get better at close-up shots or shooting into melee or shooting off rays while he's moving or riding a horse.The DM is always right, but since I DM as well as play, I'd like to have a good answer for this question. Any considered opinions on this?
