Ive read thread after thread on Chill Touch, but I still am not concrete on the spell, and its relation to both the Touch Attack rules and the Holding The Charge rules. So I'm going to attempt to formulate this as best as I can... *deep breath*
You are a CL 3 Magus for this example
What I know about the Chill Touch spell:
-You cast the spell (provoking an attack of opportunity)
-The spell is now, for lack of better word, ACTIVE indefinitely
-As a CL 3, you have 3 charges of this spell active
-During the same round that you cast it, you get 1 free touch attack
-A Magus may trade the 1 free attack for 1 free Spellstrike
-Using Spell Blade, I have now:
* Cast the spell
* Used Spellstrike
-I am left with 1 more attack with my main hand weapon at a -2
-I cannot make a touch attack with a weapon (So I've been told)
-I attack normally with normal damage, leaving me 2 charges active
-Round 1 over
My free attack from the touch spell has been spent, which means I cannot use my Spellstrike with this spell anymore. I'm left with 2 held chill touch spells, a sword in my main hand that I cannot use a touch attack through, and a hand that is empty that could deliver a touch spell.
My offensive options for Round 2:
-Attack with weapon at full base attack bonus
*Leaves 2 Charges
-Make an unarmed attack at full base attack bonus
*Leaves 1 Charge
*Provoke attack of opportunity
-Attack with weapon and unarmed taking -6 and -4 to the attacks
*Leaves 1 Charge
*Provoke attack of opportunity
-Attack and cast a new spell
*Dissipates remaining charges
*Provoke attack of opportunity
-Round 2 over
I'm into round three now, with 1 charge left to spend, after potentially getting my ass handed to me by attacks of opportunity. I'm also facing the same bleak offensive options for this spell for my next round. This is how I've researched this spell to function like, yet I'm reading here: (http://paizo.com/paizo/faq/v5748nruor1fz#v5748eaic9r3x)
(Magus, Spellstrike): If I cast a spell that allows multiple touch attacks, can I deliver all of those spell touches through my weapon?
-Yes. For example, if you cast chill touch (which allows multiple touch attacks), you could use Spellstrike to cast and deliver the spell through your weapon, and in later weapon attacks you could use your weapon to deliver the remaining spell touch attacks (one spell touch attack per weapon attack).
-If you have multiple attacks per round with that weapon (such as from having a BAB of +6 or higher), you can use the weapon to deliver multiple spell touch attacks per round, so long as you have uses of that spell touch attack remaining.
-For example, if you are an 8th-level magus (BAB +6/+1) and you cast chill touch, you have up to 8 uses of that spell touch attack. If you make two weapon attacks in a round, you can deliver two spell touch attacks per round (one for each successful weapon attack)
I don't see how that works when Spellstrike specifically says "Instead of the free melee touch attack normally allowed to deliver the spell, a magus can make one free melee attack with his weapon (at his highest base attack bonus) as part of casting this spell". Spellstrike is a "free" melee attack used in place of the "free" melee touch attack. As far as I can tell, when you cast a touch spell, the first touch attack is free, and the rest of them you have to use an attack action. Am I not understanding this correctly?
