Hello everyone, I am considering making my 4th level fighter a level 1 magus when he has enough XPs for 5th level. I also want to do this for PC level 6th and 7th making him a level 4 fighter/level 3 magus. I have gone and looked thru the posts about what a magus can and cannot do in regards to spells and attacking. Something’s are simple like spell combat and spell strike. As I understand it, spell combat is analogues to two Weapon Fighting. You wield a weapon in one hand and cast a spell with the other, and I am aware of the -2 penalty involved (just like two weapon fighting). I also understand that spell strike means that you can discharge a touch spell thru the weapon. So if you want to cast shocking grasp you would declare that you are using your spell strike ability to attack with your weapon (doing normal damage if you hit) and on a successful attack you discharge the held spell (in this case the shocking grasp electrical damage).
Now my question comes with those spells that have multiple uses based on level. Let us say I am a level 3 Magus (as outlined above) and I have chill touch, per the spell I can use it 3 times (1 per level of Magus) Now if I elect to use spell combat I will be able to cast a spell and attack with my sword. i.e. touch target, do damage, attack with weapon, do damage… so far simple. Now if I also elect to use spell strike I will use my weapon to attack to deliver the spell (mind you I only have one weapon), If I hit I do weapon damage and spell effect, since I was doing spell combat I just used the spell portion of it and now I have an attack, so I attack with my weapon (again). Since casted chill touch (thru the weapon) and I have three uses of it, does that mean that when I make my (what would be my normal) attack with it that another charge of the chill touch would go of (if I successfully hit)?
Although it is not specifically spelled-out in RAW, the RAI appears to be that held charges of a touch spell can be delivered via a magus's weapon on subsequent attacks - so yes, if you have charges remaining Chill Touch because you are a higher level character, every time you hit with your weapon, you will deliver a charge (and therefore deal weapon damage plus Chill Touch damage).
If, however, you cast any other spell (touch spell or otherwise) while you have held charges from Chill Touch, the remaining charges will dissipate.
OK, I understand casting other spells making you loose remaining charges (thanks), just wanted to clarify the point. It seems to make sense to me, but then what makes sense to me may make another person think I am breaking the game :-)
