So anyway, a touch attack specialists would benefit from said weapon specialisation plus the best touch spells. Ten cleric levels gives you access to nearly all of the best touch spells, so that seems like a given.
I'll want to focus on Dexterity? Strength has zero impact on touch attacks, so weapon finesse seems mandatory. Since I'm not taking it beyond level 5 divine spell casting, a Wisdom score of 15 seems like a bare minimum (assuming for a moment my attack rolls and saves will be ok). As for feats.. extra spell slots, or would that be a waste?
Beyond that.. I'm out of gas. CCCD. Anyone know of a novel way to fill up the remaining levels? Shadowdancer levels, Monk levels, well.. those are kind of a given. I'm all ears for suggestions. My last build had four class types (five if the engine had allowed it), so I don't mind if things get a lil' complicated.
