No. For spells specifically there is only the ray talent line that improves that sort of spell of which Octavia casts a lot, notably Scorching Ray, Disintegrate and Hellfire Ray. I am pretty sure it affects the cantrips as well. General ranged talents like Point Blank Shot and Precise Shot, which are basically mandatory for any AT, work on ranged touch attack spells.
Thanks. I assumed it was useless, but just wanted to confirm there wasn't some weird Pathfinder thing about hit chance on your main weapon effecting your spells or something. Hopefully I got precise shot, I'll check, but it could be confusing since I believe it says "ranged weapon" which doesn't scream magic. I can see why there was so much confusion for Pathfinder newbies, though usually a quick google search explains things. I'll give my cool bow to Linzi then, though she barely ever fires it really. Just got the alchemist guy and... not a fan. Linzi's buffs seem way more important.
Just had a fun and challenging fight to save the mage from trolls. Overall "challenging" difficulty isn't that hard IMO, though I got to the troll base and the guys at the door were impossible, so I must be underleveled. I have no idea how long it takes before trolls effect your kingdom, so... we'll see what happens while I do some other things. The will 'o wisps from the well raped me too.
