I am going to start with a summary, taken from the rules of the HARP combat sequence…
1 Make an attack roll. This is an open-ended percentile roll.
2 If the initial roll is within the fumble range for the weapon,
the attack stops and you roll on the fumble table. If the initial
roll is within the open-ended range (96-100), you roll
again and add the two rolls together. If the second or any
other subsequent roll is between 96-100, you roll again and
add it to the previous total.
3 Add your character’s OB (Offensive Bonus) to the final
4 Subtract your foe’s DB (Defensive Bonus) from the adjusted
die total. This is your Total Attack Roll.
5 If the Total Attack Roll is 1 or higher, then you have hit
your foe. Now that you have determined that you have hit,
adjust your Total Attack Roll by adding or subtracting the
size modifier for the weapon that your character is using.
This is your Adjusted Attack Roll.
6 Look up your Adjusted Attack Roll on the proper Critical
Table, as determined by the Attack Type for the weapon
that you are using. This is the damage that you have done
to the foe. All damage is applied immediately.
The first big difference is No Attack Table.
That is slightly disingenuous as ever group of related weapons has its own attack table which combines caps for attack size, mods to differentiate the weapons and weapon specific critical tables. There is an example of one of these below so you can see how it works.
But without an attack table how do we account for armour?
Armour is modelled using a combination of DB bonus and Maneuver penalty. So heavier armours are more protective but more restrictive. Armour can be bought as full suits or accumulated piecemeal. Armour also comes as fitted or unfitted.
When armour is fitted to the character is has a massively reduced maneuver penalty. Unfitted armour is no where as easy to wear. All unfitted armour has double the maneuver penalty of fitted armour including doubling the minimum maneuver penalty. These penalties apply to all skills that have QU or AG as a stat.
I really like that last restriction. It is really simple and clear and should more skills be added in other books it is immediately obvious whether there are penalties or not.
HARP details 12 types of armour and 9 location specific elements and/or two complete sets (either with a shirt/hauberk style or breastplate style).
I personally find the Armour system to be incredibily easy but also detailed. The only flaw of course is that if the protective value of a suit is a flat DB bonus against all attacks then you cannot differentiate between a blade and a hammer which of course individual attack tables, that we are used to, can reflect.
The biggest flaw in the combat system is the criticals. There are only 19 specific criticals for each weapon. What this means is that the same criticals come around again and again.
Imagine you have 5 orcs using scimitars and the PCs are using a mix of broadswords and longswords. Basically every attack is going to do a critical every time. You could easily dish out 40 criticals (8 combatants over 5 rounds is not unreasonable for a common encounter). Statistically every critical would come round at least twice and two or more more than twice. (40 occurrences of 19 possible outcomes). Combat becomes very samey. The strength of Rolemaster combat is that those ‘special’ criticals are rare enough to be special.
The strength of the system is that the entire combat runs off of one page so there is no page flipping between weapons charts and critical tables so it goes quickly but a cost, in my opinion.
It always seems to me that HARP players hanker after RM combat tables the same way that RM players look at HARP magic is a certain envy. That is not an imagined thing either, there is a replacement HARP combat system under discussion on the forums if you agree to the NDA.
- The combat chapter lists 18 common combat actions over and above just hitting ot shooting your oponent. Along with each are the rules need to resolve each. This is far more extensive than any I remember seeing for Rolemaster but I could be mistaken. Either way for these to be in the standard core book is a great inclusion.
- Blade Slap
- Disarm Foe
- Disengage from Melee
- Fencing Slash
- Full Parry
- Hold at Bay
- Move & Attack
- Multiple Parry
- Press & Melee
- Power Strike
- Stave Jab
- Shield Bash
- Sudden Dodge
- Weapon Bind
So that is a round up the the combat chapter. HARP is a lighter game than Rolemaster and I think this is one area where that lighter ruleset is most apparent. I don’t think any RM player is going to ditch Arms Law for the HARP combat system despite there being a lot of great stuff here.
