I have a problem, I consider combat too humdrum and think it does a terrible job of simulating a cinematic (key word) duel.

We've been using opposed attack rolls combined with Armor as DR. but its sort of a hodge podge of stuff I've put together over the years and one of my players mentioned in passing (two or 3 times.....) that it might be nice if the whole system is written down so he can plan out this feats and such more ahead of time.

Since I consider this a fairly reasonable request I sat down to do so. After perusing a thread here about feat taxes I figured I should run the numbers for some default combat styles and their results before finalizing it and posting to our group website.

And then came the potential issue......

Heres the rules as i have them currently. Its mashing my current favorite system (dark heresy) with pathfinder. Of note is that HP does not add to hit points, only to your damage reduction.




To-hit unchanged, damage equals damage as normal. Exploding damage dice.

Defense:
Flat out AC. And then the active defenses; parry and dodge defense.

AC:
10+Shields cover bonus, deflection bonuses, dodge bonuses, misc.

*a shields cover bonus is 2 for small shields, 4 for large shields, 6 for tower shields.
*Deflection, is shields and anything that gives a bonus and names the bonus as “deflection”.
* Dodge bonuses are labeled as such and include Dexterity and the dodge feat as well as bonuses from spells like haste.
*MISC Include things like luck bonuses, protection from evil
bonuses and insight bonuses.

PARRY BONUSES COME IN 2 FLAVORS, WEAPON AND SHIELD PARRIES.

Parries are reactions just like attacks of opportunity and like attacks of opportunity you only get 1 per round and if you take one as your reaction you do not get an AoO. The combat reflexes feat increases your number of reactions each round as normal for the feat.
*Dodge actions are an exception to this rule. You can always attempt a single dodge reaction in a round.
* Having a weapon in each hand (or a sword and board) allows you to make a parry with each weapon, each round.

PARRY SHIELD:
base attack bonus+shield bonus+dexterity bonus+shields magic bonus if any.

PARRY WEAPON:
base attack bonus+ skill feats (weapon focus etc.) +dexterity bonus.
*unless a weapon has the defender magical ability its magic bonuses are not added to this parry roll.

DODGE DEFENSE:
Dodge defense is your acrobatics skill+ feats like dodge or lightning reflexes. A successful dodge can move your character 5 ft in any direction if the dodger wants to do so.

DAMAGE:
Damage is the weapons dice of damage + Strength mod+ equipment mods+ feat mods+ the difference between the attack roll and the targets base AC. NOT the targets parry result.
Naturally this means you can get messed up in a hurry, so sound tactical planning is a good idea. A good attack roll is then also a great way to damage someone in heavy armor.

CRITICAL HITS:
A critical hit bypasses both Armor and toughness bonus from CON.

ARMOR:
Armor prevents you from being hurt when you get hit. It does NOT however make it harder to hit you, as a rule. Armor gives you a bonus of 1-6 to your DR before magical enhancements. Some better materials can increase this number as well.

DAMAGE REDUCTION:
Your damage reduction is equal to your Constitution bonus and your armors DR, as well as any natural armor. Damage reduction bonuses such as a resistance to non magical weapons are figured first so they can be easily ignored if the attacker has such a weapon.

2 combatants

BOB:
Chainmail, shield, long sword, Str16, Con 16, Dex 12 FEATS; focus, toughness BAB:1 TOTAL:5 DAMAGE 1D8+3 AC 15, PARRY 16 DR 4armor+3 con=7 HP; 10 human+4 1st fighter+3 toughness = 17

KRAG: dwarf.
Chain, Great axe.Str 16, Con 18, Dex 10 feats:focus, toughness BAB:1 TOTAL:7 DAMAGE 1D12+5 AC 10, PARRY 2 DR 4armor+4 con =8 HP: 12 dwarf, +4 fighter 1 +3 toughness = 19



Result? Given average D20 rolls of 10 Bob cant miss Krag. Krag cant parry. Bob rolls 4 damage and adds 5 for his total over 10 AC roll for 9 damage. Krag has toughness 8. So he takes 1 point of damage a round.

Krag cannot miss Bob on an average roll or be parried. His attack roll of 17 is 2 over AC 15 so he does 1d12+5(11)+2=13- DR 7 = 6 damage a round.

Great axe wins the average fight handily. He's bloodied a bit but the outcome was never in doubt.

If Bob put his 2nd feat on focus-shield instead of toughness however he would auto parry Krag with average rolls. Meaning 1 point at a time he would wear Krag down and win without a scratch.

Result= feat tax. And then the feat is overpowered.

* against multiple attackers however the extra parry each round for the sword and board fighter gives him a major edge in survive-ability over the great weapon wielder.




So what I have here is that 1 on 1 with the same feat selection the great weapon fighter crushingly wins everytime. With a feat tax the sword and board wins everytime, and against multiple enemies the great weapon wielder is likely chopped into bits fairly easily while the the sword and boarder has a chance to wear them down.

I'm not sure if this is a good result, bad result or indifferent.

So I'm looking for opinions here on what people think about the results, the rules, etc. So that I can potentially tweak it.
 

Ok, I only gave a cursory glance to everything after you introduce two types of parries. First, if I get this correctly, shields give a AC bonus for cover AND deflection. Makes me want to carry a shield.

Now to the cursory glance and why. If you introduce all these new "combos" if you want to think of them like that, they might be cinematic in flavor, but the game still has an action economy. So you still have to decide which parry to use or save it for an attack of opportunity. Makes combat reflexes a better feat, at least in my opinion. Have to read and comprehend all the stuff after this point.
 

basically all true. Except that i worded it badly with shields. They add to the base AC with their Cover bonus but add to a shield parry with their deflection bonus. (which i houseruled to be the same numbers, but terminology is important. )
