"They are not allowed. The same penalty applies to all and as you have stated, ML clearly outlines this."
Actually this is incorrect. Melee users have the following restictions "Combat Modifiers - Only piercing type weapons can be used effectively underwater and receive a -20 OB modifier; all others have a –50 OB modifier because the water resistance to motion is too much to use any other kind of weapon with great effect, except nets."
My point is that melee users have different allowances compared to others. This is against your comment of ""Allowing melee weapon wielders to do one type of action whilst denying the same action to someone else solely based upon their choice of weapons (ranged, thrown daggers, etc or spells) is entirely AGAINST the authors intent. So this point is unfortunately, entirely wrong and moot."
If you'd like to moderate or change this view point, please feel free as it's pretty conclusive that the current statement is incorrect.
"What attack would the attacker with the mirror do? " I think you missed the point. Flashing reflected light into the opponents eyes is the Dirty Trick. It's not an attack in any way, shape or form.
"But in that case spell casters and what they can do ARE explicitly written into the skill." I agree entirely which is one of my original points when I said "A character gains access to the different categories based upon how many skill ranks that they have in their weapon." as listed in ML. And in HARP core where it says ""In the chaos of melee combat, characters are usually concerned only with landing a successful and damaging blow upon their foe. There are, however, a variety of other actions that a character may perform during combat. Called Combat Actions, they represent only a few of the potential actions that characters can take."
Both quotes relate to weapons and melee combat which I would say leads directly into your comment " But in that case spell casters and what they can do ARE explicitly written into the skill." My argument is that IMO, what spell casters can do IS already written into the Combat actions as well. If they have a weapon they can perform combat actions if they have enough ranks in the weapon skill. NOT spells.
"So, according to the Harp Core, what combat actions can a spell caster take?
According to your argument, they certainly cant cast spells as they are not explicitly mentioned." You may want to check out HARP core chapter 11. It has a whole chapter on spell casting. Also, there is a whole book called College of Magic which relates to spells, spell casting etc They can also use any Combat action listed provided they have the ranks and the correct weapon. What I'm saying they can't do is transfer combat actions to spell casting.
"Rasyr has already written in the Errata and clarified that spellcasters should be allowed to take any action that others would normally be allowed and has clarified this in all the examples that people put to him in 2004."
I unfortunately, haven't got the errata and can't seem to find it in the vault. I look forward to checking your copy. What I will quote is from Elessar previously "Well, you can see errata p.69. For this question, Tim answered :
""I don't see why not. Just treat it the same as the Move & Attack Combat Action. For multi-round casting, the penalties from each round would be combined."
To be honest, reading the response from Tim, it doesn't look like much time, thought or effort was put into the answer. It seems to me like a quick, off the cuff comment without the benefit of considering effects or play testing. I would be interested to know what was the basis of the decision and if play testing was under taken.
"Would you also deny the fighter the ability to take a 5 foot step and attack a foe because he cast bladeturn on himself last round? According to your interpretation on the rules he should."
HARP core says "Certain spells are marked with an asterisk (*) beside their name. These spells are instantaneous in regards to casting time. A character may cast one of these spells at any time, except while he is casting another spell. When cast, it does not count against the character’s action for the
round."
So the answer is no. The fighter can perform an instantaneous spell and move. In fact, in the same round, he could cast an instantaneous spell and perform a combat action without penalty. The only time an instant spell affects a player is if a caster is casting a multi round spell and is, therefore, not allowed. If you were trying to use a non-instant spell as an example, then yes, the fighter could not move since it takes a full round to cast a non-instant spell. (However, yes we do allow a 5' step as a house rule for all classes during combat.)
"... or from say a spell he is casting.... We know warrior mages use their weapons as spell foci and thus are allowed to weild them using the somatic talent as if they had a hand free.
This clearly allows spells to be an offensive weapon. This weapon, thus can also be used to attack, or parry or perform other actions."
Wow...That statement is hugely faulty logic. How does using weapons as spell foci jump to "This clearly allows spells to be an offensive weapon." By this logic, a wand wielding Nagazi can use his wand as a sword. A weapon as a focus is still a weapon, it just has the advantage to help casting. It doesn't make the spells more offensive in anyway. (If the warrior mage cast minor healing using his weapon focus, are you now saying it's an offensive spell because a weapon was used in casting?)
"Since the spells have no physical form they cannot be used to "parry" a physical object." I agree entirely. My point is why do spell casters get to pick and choose what they can and can't use in combat actions? My Paladin would love to be able to do a spinning slash attack but it's limited to bladed weapons and my weapon is concussion. I would love to be able to perform a Shield Bypass (Major) but I don't use chains. There are heaps of examples where exclusions to groups apply so why is it so unfair to limit combat actions to weapon use? It doesn't stop spell casters from using the skills with weapons, just with spells. Plus, if I'm a pure fighter (i.e. don't use or cast spells and have no ranks in such) then why do combat actions have a (potential) greater bonus to spell casters than non-spell casters? Spell casters can invest ranks into weapon skills and have the same access to combat actions as a fighter but they can also (in your opinion) use combat actions for spell casting. All of a sudden, actions that were developed to assist fighters can now help spell casters more.
There was also a post made prior to this area of discussion. I don't know if you saw it or not as the points were not addressed.
