GURPS Quick Reference

GURPS has a number of social skills. They differ not in what you can do with them, but how you do it. You can pursue any goal with any social skill.

Here's what they mean:

Diplomacy:
The art of reaching agreements. Used in place of noncombat reaction rolls by figuring out others' actual priorities to make better offers of compromise, leading to agreements that are likely to endure. Failures using this skill won't result in a worse reaction than a standard reaction roll.

Fast-Talk: Short-term persuasion based on confusing people and putting them off-balance. You can use it to get people to believe lies or agree to things not in their best interest... but only until they have time to think things over. On a failure, the other character knows you were trying to trick them and gets indignant.

Intimidation:
Getting cooperation through threats or displays of ruthlessness. A critical success may induce terror. A failure leads to contempt.

Savoir-Faire: Getting along in a specific subculture using the correct protocol. Knowing the correct way to act for favors. Failures indicate offensive bluntness.

Sex Appeal: Gain cooperation by suggesting sexual availability, or by making people find you alluring. You don't have to deliver, and you can use this to tease people or make them nervous. Failures come off as creepy or ridiculous.

Streetwise: Getting along with criminals or in rough neighborhoods. Knowing how to ask for illegal services without generating mistrust. Failures make you seem like you don't know your way around.

Remember, you can use any of these skills to try and accomplish your goals. Other skills (Carousing, Dancing, Games, Leadership, Merchant, Public Speaking, and Writing) can also influence people in narrow ways in specific situations.

Using social skills on PCs:


These skills aren't mind control, however, if someone succeeds in using a social skill on you, you'll want to go along with them. Roleplay that. Roleplay resisting what you want, if that's your choice, but you get a -1 x their margin of victory when acting against what they made you want.

So if someone wants to Intimidate you into leaving but you'd rather stay and play video games, and their intimidation roll beat your Will roll by 3, you'd be at -3 on rolls involving not leaving.

Unarmed Combat Skills

Okay, here's a breakdown of what the unarmed combat skills do:

DX: Punching, kicking, grappling, biting, slamming into people.

Brawling (DX/Easy): Punching, kicking, slamming into people, biting. Blackjacks, saps, and other fist-loads. +1 damage at DX+2 level.

Boxing (DX/Average):
Punching. Retreating parries get +3 instead of +1. +1 damage at DX+1, +2 at DX+2. Not so good at parrying swung weapons.

Karate (DX/Hard): Punching. Kicking. Retreating parries get +3 instead of +1. +1 damage at DX+1, +2 at DX+2.

Wrestling (DX/Average): Grabbing people. Making or resisting a takedown. Add +1 to effective ST at DX+1, +2 at DX+2.

Judo (DX/Hard):
Grabbing people. Throws. Retreating parries get +3 instead of +1.

Sumo (DX/Average): Slamming into people. Grappling. Shoves. Retreating parries get +3 instead of +1. +1 to effective ST at DX+1, +2 at DX+2.

That's the basics. Different martial arts techniques are based on different skills; Arm Lock, for example, can be performed with Wrestling or Judo but not Brawling, Boxing, or Karate.

This list may be information overload, so you're free to ignore it, but from GURPS Martial Arts, here's how the different skills allow different "techniques." You can still attempt any technique even if you haven't put any points in it; defaults are listed. Generally you need to study a particular style to improve that style's techniques.
Technique	      Boxing Brawling Karate   Judo Wrestling  Sumo

Wrench Limb		-	-	-	-	-	-	Defaults from ST
Wrench spine		-	-	-	-4	-	-	or default from ST.
Again, if you don't care, ignore this; when you attack someone I'll choose whatever is closest to what you've described.

* Taking an active defense spoils your Aim; if you are injured, make a Will roll or lose your Aim.
** Before or after attack.
† Taking an active defense or being knocked down, injured, distracted etc. requires a Will-3 roll to maintain.
‡ The attacker cannot parry with the hand(s) he used to attack, block if he attacked with his shield or cloak,
or dodge if he kicked. He can use any other defense, but at -2. He cannot retreat.
§ If you attacked using an arm, you cannot use that arm to parry (if the attack involved a fist, elbow, or
weapon) or block (if you used a shield or cloak). If you used any other body part to attack, you cannot dodge.
You can use any other defense, but you cannot retreat.
Deceptive Attack	Target suffers a -1 to active defense for every -2 taken to melee skill (min. skill of
			10), or -1 to Dodge for every -2 taken to ranged skill (min. skill of 10).
Pop-Up Attack (B390)	Ranged attacks only, attacker suffers -2 to hit, no aim possible, may step. Not
			possible with bow or sling
Rapid Strike (B370)	Make two attacks, both at -6, to replace one normal attack. Can target seperate foes.
			Ranged Rapid Strikes if RoF 2+. Half penalty for Weaponmaster or Gunslinger
Riposte (MA124)		Take a penalty to your Parry (min. of 8), not including modifiers. If Parry succeeds
			and you attack using the parrying weapon next turn, apply the same penalty to your foes
			Parry (hand or weapon), Block (shield) or Dodge (non-hand unarmed strike) or half that
			penalty to all other defenses.
Stop Hit (MA108)	Take a Wait Maneuver and declare that you intend to attack. Both roll to hit. Both
			fail, nothing happens. If one hits, the other defends at -1 or -3 if Parry with same
			weapon. If both hit, larger margin of success defends normally, other at penalty above.
			If tied, both have above penalty. Possible with Unbalaced/Unready Weapon.
Spraying Fire (B409)	RoF 5+ weapon may attack multiple targets, must be within 30° angle, engaged in
			succession, +1 Rcl 2nd target +2 Rcl 3rd target and so on. RoF -16 looses 1 shot/yard,
			RoF 16+ looses 2 shot/yard. Attack roll for each target with effective RoF
Telegraphic Attack 	+4 to hit, +2 to defend against. Not compatible with Deceptive Attack, Evaluate,
			Riposte or Feint. Does not affect critical chance.
Tip Slash (MA113)	Swing a thrusting, impaling weapon to do cutting damage equal to the weapons impaling
			damage -2
Extra Effort		A critical failure on these rolls causes an additional 1 HP of injury to arm (block,
			parry, attack) or leg (dodge or kick), no DR (B357). May use no more than one offensive
			option (Flurry of Blows, Giant Step, Great Lunge, Heroic Charge, Mighty Blows)
   Flurry of Blows	Spend 1 FP per attack to halve the penalty for Rapid Strike to -3 (B370, usually -6, if
			you spend 1 FP you half it to -3)
   Giant Step		Spend 1 FP for one extra step (before or after your attack) during an Attack or
			Defensive Attack.
   Great Lunge
			Spend 1 FP to get the effects of All-Out Attack (Long) without losing defenses
			(incompatible with All-Out Attack, Defensive Attack, Defensive Grip).
   Heroic Charge	Spend 1 FP during a Move and Attack to ignore the skill penalty and cap (except for
			Acrobatic Attack or Flying Attack).
   Mighty Blow		Spend 1 FP per attack to get the All-Out Attack (Strong) damage bonus to an Attack
			without losing defenses.

	Heart		-5		[1,11]

[1] Attack that misses by 1 hits the torso instead.
[2] Only imp, pi, and tbb attacks can target the eye – and only from the front or sides. Injury over HP/10 blinds the eye. Otherwise, treat as skull [3], but without the extra DR!
[3] The skull gets an extra DR 2. Wounding modifier is ×4. Knockdown rolls are at -10. Critical hits use the Critical Head Blow Table (B556). Exception: These special effects do not apply to tox damage.
[4] Jaw, cheeks, nose, ears, etc. If the target has an open-faced helmet, ignore its DR. Knockdown rolls are at -5. Critical hits use the Critical Head Blow Table (B556). Cor damage gets a ×1.5 wounding modifier, and if it inflicts a major wound, it also blinds one eye (both eyes on damage over full HP). Random attacks from behind hit the skull instead. On front hit, roll 1d. 1 means skull [3] hit if attack is imp, pi, tbb. Otherwise it’s a nose hit [15].
[5] Limb. Reduce the wounding multiplier of large pi, huge pi and imp damage to ×1. Any major wound (loss of over 1/2 HP from one blow) cripples the limb. Damage beyond that threshold is lost. Roll 1d, on a 1 cut, imp, pi, tbb hit vein/artery, see [17]. Cr hits a joint [15]
[6] If holding a shield, double the penalty to hit: -4 for shield arm, -8 for shield hand.
[7] Human males/males of similar species suffer double shock from cr damage, and get -5 to knockdown rolls. Otherwise, treat as a torso hit.
[8] Extremity. Treat as a limb, except that damage over 1/3 HP in one blow inflicts a crippling major wound. Excess damage is still lost. Roll 1d, on a 1 with cr, cut, pi, tbb hits a joint [14].
[9] If rolling randomly, roll 1d: 1-3 is right, 4-6 is left.
[10] Neck and throat. Increase the wounding multiplier of cr and cor attacks to ×1.5, and that of cutting damage to ×2. At the GM’s option, anyone killed by a cutting blow to the neck is decapitated! Roll 1d, on a 1 with cut, imp, pi, tbb hits vein/artery [17], if cr from behind, counts as [16] and gives Quadriplegic. Automatic if dmg > HP from Neck Snap or throw from Head Lock.
[11] Heart, lungs, kidneys, etc. Increase wounding modifier for imp or pi attack to ×3. Increase wounding modifier for tbb attack to ×2. cr is only ×1, if caused shock roll vs. knockdown, -5 if major wound, other attacks cannot target the vitals.
[12] Ear, if cutting max Dmg = HP/4, double HP/4 removes ear which gives -1 Appearance
[13] Jaw, if crushing extra -1 to knockdown
[14] Joints, limb crippeld at HP/3, extremity at HP4, HT roll to recover from crippling -2, miss by 1 hits the limb or extremity not the joint
[15] Nose, only targetable from the front, treat like facehit, HP/4 breaks nose gives major wound and no Sense of Smell/Taste until healed. Cut lops off nose if HP/4×2 (major wound) but knockdown not at -5 for face. Cutting off nose = Appearance -2
[16] Spine, only targetable from behind with cr, cut, imp, pi, tbb. DR3, if shock-penatly roll against knockdown, crippled if dmg = HP which causes automatic knockdown and stunning
[17] Veins and Arteries, only targetable by cut, imp, pi, tbb. Increases wounding modifier plus 0.5, no crippling and no dmg limit, an attack that misses by 1 hits the neck, arm or leg, as appropriate
[18] Roll 1d if cr, imp, pi or tbb. On 1, hit to the vitals [11], cut from behind hits the spine [16]
[19] Like [18] but if major wound you fall down. Until healed you’re Lame(Missing Leg). Can’t stand, fight sitting or lying. Armor for torso and groin or specific protects normal.
[20] Roll 1d, 1 is Vitals [11], 2-4 is Digestive Tract [21], 5 Pelvis [19] and 6 is Groin [7].
[21] If major wound HT-3 or get a special infection (B444)
