Skill Combat

Paizo's performance combat system can be adapted to create skill challenges. Here's how. You can adapt these rules for other forms of "Combat" as well, especially if you want to run a series of extended and opposed checks (such as for a heist, with the crowd representing a building or structure and its inherit difficulty).

Skill Combat

Sometimes, characters sometimes find themselves among a crowd, or even an individual, where the reaction is at least as important as a hand-to-hand combat. They may find themselves in the middle of hostile terrain, where their overall survival depends on how well they work together. Whether a debate, a wilderness trek, or a hurriedly given speech, Skill Combat can provide a framework for skill-based encounters.

Skill combat can represent encounters that involve:

• Influencing a crowd
• Gathering information
• Sneaking through a large camp
• ...and more

Characters are able to influence the check through their skill ranks as well as RP choices.

The Skill Combat Sequence

The skill combat sequence is as follows:

1. GM determines the difficulty of the initial challenge. This is based on two factors:

Overall Difficulty on a scale of 1-5

Any modifiers, most commonly the number of NPCs to be affected

2. PCs take an action that results in an appropriate skill combat check.

3. Apply modifiers.

4. Determine results.

5. Reward or subtract a victory point based on results.

Set the Initial Skill Combat Difficulty

The GM will set the initial difficulty of the Challenge, based on a scale of 1-5, with 1 being the easiest and 5 being the most difficult.

Skill Challenge Base Difficulty
Challenge	Starting DC	Descriptor
5 "Hostile"	20	The Hostile difficulty imposes a –2 penalty on all attack rolls, combat maneuver checks, ability checks, skill checks, and saving throws. This is a mind-affecting effect. If the PCs are attempting to sway a crowd, a caster may not attempt to influence a hostile crowd while casting a spell. If the crowd is hostile towards a group and a member of that side fails a their Skill Combat check by 5 or more, that side automatically loses that part of the combat.
4 "Unfriendly"	15	Unfriendly crowds and situations have a demoralizing effect. The unfriendly difficulty imposes a –1 penalty on all attack rolls, combat maneuver checks, ability checks, skill checks, and saving throws. This is a mind-affecting effect. If the PCs are attempting to sway a crowd, a caster may not attempt to influence an unfriendly crowd while casting a spell.
3 "Indifferent"	10	Indifferent crowds and situations can be potentially open-minded or open-ended, but may swing either way. Audience members show little emotion other than anticipation and a desire for daring feats of combat to occur. A township may shrug its shoulders.
2 "Friendly"	15	A friendly crowd or situation grants a +1 morale bonus on all attack rolls, combat maneuver checks, ability checks, skill checks, and saving throws for their chosen side. This is a mind-affecting effect. At this difficulty, the crowd or situation is beginning to be swayed toward one side.
1 "Helpful"	20	Helpful crowds and situations are helpful and supportive. This difficulty grants its chosen champions a +2 morale bonus on all attack rolls, combat maneuver checks, ability checks, skill checks, and saving throws. This is a mind-affecting effect.

Does the Size of the Crowd Influence It?

This can refer to the number of people in a crowd, an enemy camp, a township, and so on.

The base DC is modified by the size of the crowd, the number of participants on each side, and a number of other circumstances.

Size of the Crowd: Larger crowds are harder to sway to one side or the other. It takes great shows of daring or a progression of numerous displays of crowd-pleasing actions to get them to change their attitude. Presented here are the general crowd sizes and their effects on the DC to improve crowd attitudes and gain victory points.

Small Crowd: A small crowd contains no fewer than two and no more than 25 creatures. It does not increase the base DC of all influence combat checks.

Medium Crowd: A medium crowd contains no fewer than 26 and no more than 100 creatures. A medium crowd increases the DC of all influence combat checks by +2.

Large Crowd: A large crowd contains no fewer than 101 and no more than 300 creatures. A large crowd increases the DC of all influence combat checks by +3.

Massive Mob: A massive mob is made up of no fewer than 301 creatures, and its numbers can expand into the thousands. A massive mob increases the DC of all influence combat checks by +4.

Total Number of Combatants: The participation of a large number of combatants increases the difficulty of swaying the crowd. Large groups of combatants make it difficult for a crowd to follow the entire battle and to catch actions from individuals that could possibly sway the audience's attitude. Adjust these modifications as combatants enter or leave the battle.

Small Battle: If the battle is between a total of 2–8 combatants, there is no change to the base DC to improve the attitude of the crowd or gain victory points.

Medium Battle: If the battle is between 9–16 combatants, the DC to improve the attitude of the crowd or gain victory points increases by +4.

Large Battle: A battle with 17 or more total combatants increases the DC to improve the attitude of the crowd by +8.

Other Influencing Factors

Other circumstances that always affect the DC to improve the attitude of the crowd or gain victory points include the following.

Cheating: If one side visibly cheats or breaks the rules, the DC for that side of the influence combat to improve the attitude of the crowd increases by 2 for the remainder of the influence combat. This increase can occur multiple times in a battle. For the purpose of spotting cheating, determine the base Perception and Sense Motive for the average member of a crowd (usually +0 if you assume an average human) and apply the following modifiers based on crowd size. The DC is based on whatever action the combatant is using to hide any cheating (usually Bluff or Stealth).

Crowd Size	Bonus on Perception and Sense Motive Checks to Spot Cheating
Small crowd	+8
Medium crowd	+12
Large crowd	+16
Massive mob	+20

Outnumbered: If one side of the battle outnumbers the others by less than a 2:1 ratio, the DC for that side to improve the attitude of the crowd or to gain victory points increases by 2. If one side outnumbers all others by a ratio of 2:1 or more, the DC for that side to improve the attitude of the crowd increases by 6. These increases to the DC end or are reduced to the appropriate level if the numbers become even or if the 2:1 ratio of combatants is ever brought down to outnumbering the other sides by less than a 2:1 ratio.

Unfair Advantage: If one side of the battle has an obvious unfair advantage (for example, one side starts the battle in a fortified position or has better weapons and armor, or its opponents are not armed at all), the DC to improve the attitude of the crowd is increased by 2. A GM can increase the DC by as much as 6 if the unfair advantage is severe enough.

Bribery or Coercion: Crowds can be bribed or coerced. Typically a successful bribe or attempt at coercion involves paying some amount of gold based on the crowd size, and succeeding at a Diplomacy check with a DC based on the size of the crowd. If the gold is paid and the Diplomacy check fails, the side gains a penalty for cheating instead, though the gold is still spent. If the check succeeds, the DC to improve crowd reaction and gain victory points decreases by 2. For every 5 points over the DC by which the combatants make the check, the DC to improve the crowd's attitude or to gain a victory point decreases by 1.

Crowd Size	Influence DC	Gold Paid
Small crowd	DC 15	25 gp
Medium crowd	DC 20	250 gp
Large crowd	DC 25	750 gp
Massive mob	DC 30	2,000 gp

Determine PC and NPC Modifiers

Whenever a PC, or NPC, has a chance to make a difference in Skill Combat, he or she makes a check. Parties can also make a check together. The check is an Attribute Bonus check modified by ranks in an applicable skill.

PCs could also gain a +1 or a -1 for things like opposing nationalities, faiths, and so on.

Hit Dice	Bonus on Skill Combat Check
0	+0
1–5	+1
6–10	+2
11–15	+3
16+	+4

Highest Skill Ranks	Bonus on Skill Combat Check
0	+0
1–5	+1
6–10	+2
11–15	+3
16+	+4
