NI 24 / ABY 34 — New Galactic Empire = good guys, New Republic = bad guys — gritty lethal standalone
Problem: M&M lets a lightsaber hurt a Super Star Destroyer if you roll well, and lets a Super Star Destroyer's turbolaser snipe a Jedi on a speeder bike. Star Wars doesn't work that way. This doc codeifies scale so each tier fights its own tier, and punishes cross-scale attacks in both directions. Inside each Scale, M&M Growth/Shrinking still matters — an Ewok is harder to hit than a Wookiee, even though both are Personal.
| Scale | Tag | Examples | Size Rank (M&M) | Typical Toughness | Typical Damage | Hands |
|---|---|---|---|---|---|---|
| 0 Personal | P | Human, droid, Ewok (Small), Wookiee (Large Build) | -3 to -1 | 0–8 (armor) | 2–8 (blaster 4-6, lightsaber 8-9, rocket 10) | FGT/Ranged |
| 1 Ground Vehicle | V | Speeder bike, landspeeder, airspeeder, swoop | -2 to -1 (Medium-Large) | 8–10 | 6–10 (light blaster cannon 6, heavy repeating 8) | Vehicles (Repulsor) or Ride / Drive |
| 2 Heavy Ground / Walker | W | AT-ST (9m), AT-AT (22m), Juggernaut HAVw (26m), AAT, 2-M tank | 0 to +1 (Huge–Gargantuan) | 11–15 | 10–14 (AT-AT heavy laser 12, AT-TE mass driver 13) | Vehicles (Walker) or Drive (Tracked) |
| 3 Starfighter | S | TIE/ln, X-wing (12m), Y-wing, TIE/sa, Lambda (20m), YT-1300 (35m), Firespray (21m) | 0 to +2 (Huge–Colossal) | 9–13 + Shields 8-11 | 8–13 (laser cannon 8, ion cannon 8 Affliction, concussion 10 Burst, proton torp 12) | Vehicles (Starfighter) / Pilot |
| 4 Capital | C | CR90 (150m), Raider (150m), Arquitens (325m), Nebulon-B (300m), Victory (900m), Imperial I (1600m) | +3 to +6 (Colossal–Awesome) | 13–18 + Shields 11-15 | 13–18 (turbolaser 13 Inaccurate, heavy turbolaser 14-15, ion cannon 12-13, tractor 12) | Vehicles (Capital) |
| 5 Titan | T | Executor (19km), Death Star (160km), Torpedo Sphere, station | +10 to +14 (Awesome+ ) | 20–25 + Shields 15-20 Impervious | 18–25 (superlaser 25 Linked Weaken 25, heavy batteries 15) | Vehicles (Titan) - not player |
M&M size rank baseline: ordinary human = -2 (3-6ft). Every 4 ranks Growth = +1 size rank. Every 4 ranks Shrinking = -1 size rank.
Scale does NOT erase size differences inside the scale. A Wookiee and an Ewok are both P, but they don't have the same modifiers vs a tank. Same for AT-ST (9m, size 0) vs AT-AT (22m, size +1) — both W, but AT-AT is easier to hit.
Use M&M 3e Growth/Shrinking directly:
Growth (2 pts/rank in M&M, free here as species/vehicle stat): - Every rank: +1 STR, +1 STA (constructs: +1 STR, +1 TOU), -1 Stealth, +1 mass - Every 2 ranks: +1 Intimidation - Every 2 ranks (round up): -1 Dodge, -1 Parry - Every 4 ranks: +1 size rank (and -5ft? No, +Speed at 8 ranks) - Every 8 ranks: +1 Speed rank
Example: Growth 8 = +8 STR/STA, +4 Intim, -8 Stealth, -4 Dodge/Parry, size rank 0 (30ft), +1 Speed.
Shrinking (1pt/rank): - Every rank: -1 STR (min 1), +1 Stealth - Every rank /2 round down: +1 Dodge, +1 Parry, -1 Intimidation - Every 2 ranks: -1 Speed rank? Actually every 2 size reductions = -1 Speed. We simplify: -5ft per size rank below Medium. - Every 4 ranks: -1 size rank
Example: Shrinking 4 (Small) = -4 STR (re-bought as species), +4 Stealth, +2 Dodge/Parry, -2 Intim, -5ft, size rank -3 (2-3ft).
For Sins, we pre-bake this as species/vehicle handling, but you need to know the numbers so Wookiee ≠ Ewok:
| Sins Creature / Vehicle | M&M Size Rank | Growth/Shrinking | Game Effect |
|---|---|---|---|
| Ewok, Jawa, Gozzo | -3 Small | Shrinking 4 | +2 Dodge, +2 Parry, +4 Stealth, -2 Intim, -5ft, -4 STR (baked into species: Ewok should be STR -1 but agile) |
| Human, Twi'lek, Rodian, Bothan, etc | -2 Medium (baseline 0) | Growth 0 | +0 all — basis |
| Wookiee, Trandoshan (tall) | -1 Large-ish or -2 with Powerful Build | Growth 2 or Growth 0 + Powerful Build | If Growth 2: -1 Dodge, -1 Parry, -2 Stealth, +1 Intim, +2 STR/STA. Sins pick: Wookiee = Growth 2 (+1 STR +1 STA -1 INT -1 PRE from species plus -1 Dodge/Parry -2 Stealth +1 Intim) OR simpler Powerful Build: counts as size -1 for carry/Intim, no Dodge penalty. Recommended: Wookiee Growth 2 — he is easier to hit. |
| Speeder Bike | -2 Medium chassis | Growth 0 | +0 Handling, exposed rider (-2 to target rider) |
| AT-ST (9m) | 0 Huge (30ft) | Growth 8 | -4 Dodge/Parry base, -8 Stealth, +4 Intim, +8 STR/STA -> translated as Handling -2, TOU +2, STR 8 |
| AT-AT (22m) | +1 Gargantuan (60ft) | Growth 12 | -6 Dodge/Parry, -12 Stealth, +6 Intim, +12 STR/STA -> Handling -6, TOU +4 |
| X-wing (12m) | 0 Huge | Growth 8 | -4 Dodge/Parry but Pilot halves -> Handling -2 |
| YT-1300 (35m) | +1 Gargantuan | Growth 12 | Handling -4 |
| CR90 (150m) | +3 Colossal (500ft) | Growth 20 | -10 Dodge/Parry -> Handling -8 to -10 |
| ISD (1600m) | +6 Awesome (3000ft+) | Growth 32 | -16 Dodge/Parry -> Handling -16 to -32, but Capital Jock halves |
For play: Don't recompute. Use statblock. But remember Ewok's +2 Dodge is real when the AT-ST shoots him.
Scale difference gives Damage penalty, size difference is already in defender's Defense.
Inside Scale difference matters: A Wookiee (size -1) shooting an AT-ST (size 0) is 1 size rank difference. An Ewok (size -3) vs same AT-ST is 3 ranks. Both suffer P(0) vs W(2) = -10 dmg, but the Ewok had a harder time hitting? No — to-hit is defender's Dodge, which AT-ST already has -4 from Growth 8. Both attackers roll vs same AT-ST Defense. The difference is the attackers' own Dodge when the AT-ST shoots back.
Heavy weapons list (ignore 1 Scale step up): - Personal: Rocket launcher, thermal detonator Burst 8-10, heavy repeating blaster, disruptor, lightsaber (Penetrating 6 vs personal, but not Heavy vs Starfighter+) - Vehicle: Concussion missile, proton torpedo - Starfighter: Proton torpedo, heavy concussion, seismic charge = Heavy vs Capital (ignore 1 step) - Capital: Heavy turbolaser = Heavy vs Titan
For each Scale step you are above the target:
Then add Size Rank Dodge modifiers. Small targets already have +2 Dodge (Shrinking 4). Large targets have -1 Dodge (Growth 2).
Total to-hit vs Personal from a W-Scale walker:
Same AT-ST vs Speeder Bike (V) Tourniquet: W(2) vs V(1) = -5 to-hit +5 dmg. Bike is Medium (-2) so Defense ~14. vs +? Fair.
Point-Defense list (ignore 1 step down for to-hit only): - Capital Point-Defense Laser Cannons Damage 9-10 Accurate 2 - ISD 60x Point-Defense turrets, Foray Point-Defense etc. - Titan Point-Defense network
If you want to skip math, use this for Damage/No-Damage gate, then apply size Dodge difference separately:
| Attacker Scale | vs P | vs V | vs W | vs S | vs C | vs T |
|---|---|---|---|---|---|---|
| P (blaster, saber) | Normal (but Ewok +2 Def vs Wookiee -1 Def still applies) | -5 dmg / need Heavy | -10 / need Heavy+Pen | No dmg | No | No |
| V | +5 dmg / -5 to hit plus defender size Dodge | Normal | -5 dmg | No* | No | No |
| W | +10 dmg / -10 to hit (Ewok -12 total, Wookiee -9) | +5 dmg / -5 | Normal | -5 dmg / -5 | No | No |
| S | +15 dmg / -15 (Ewok -17, Wookiee -14) | +10/-10 | +5/-5 | Normal | -5 dmg (use torp Heavy) | -10 / need Heavy |
| C | Impossible -20 (Ewok -22, Wookiee -19) | -15 | -10 | -5 (-0 PD) | Normal | -5 dmg |
| T | Impossible | -20 (PD -15) | -15 | -10 (PD -5) | +5/-5 | Normal |
Rule: If Damage after Scale penalty ≤0, don't roll. Narration: "Your blaster pings off the AT-AT's leg armor."
Sins species currently only have Ability mods. Add Size mods:
Small (Ewok, Jawa, Gozzo): Shrinking 4 — +2 Dodge, +2 Parry, +4 Stealth, -2 Intimidation, Speed -5ft (1 square), -1 STR? But Sins already has Jawa INT+1 STR-1 etc. Recommendation: Keep existing ability mods, add Dodge/Parry/Stealth/Intim as listed. Don't double-dip STR — species STR mod IS the Shrinking STR loss. So Gozzo INT+1 STR-1 matches Shrinking -4 STR partially bought back with INT. Good.
Medium (Human, etc): 0 — no change.
Large Build (Wookiee, Trandoshan): Growth 2 — -1 Dodge, -1 Parry, -2 Stealth, +1 Intimidation, +2 STR/STA — but species already gives +1 STR +1 STA -1 INT -1 PRE. So add -1 Dodge/Parry -2 Stealth +1 Intim to Wookiee sheet automatically. If you don't want penalty, give Wookiee Powerful Build instead: counts as size -1 for Intim/Carry, no Dodge penalty. Pick one. Gritty suggests Growth 2 — Wookiees are easier to hit, that's balance for their +1 TOU.
Update SPECIES array: add sizeMod: {dodge: +2, parry:+2, stealth:+4, intim:-2} etc. Update defense calc to include size Dodge/Parry. Update skills.intimid and stealth.
Shields are Create 8-12 Selective, Check Required 5 Technology to Repair.
Gritty: Shields are Toughness bonus that recharges, not HP.
Handling (Size Mod) is not optional.
AT-ST - Walker (W) - Tier 6 Size 0 (Huge 30ft) Handling -2, STR 8 Hull 6 TOU 11 DEF 6 Fort 8 Speed 6 (60 kph). Weapons: Chin Heavy Blaster +6 Dmg 10 Ext 40/80/160, Side Light +4 Dmg 8 Linked Grenade 6 Burst 2 Quirks: Tall +5 to be hit by S+ when in open, Weak Neck: Called -5, if fail by 10+ = Head severed. Cross-Scale: W vs P = +10 dmg / -10 to hit plus -2 more vs Ewok, +1 easier vs Wookiee
AT-AT - Heavy Walker (W+) - Tier 8 Size +1 (60ft) Handling -6, STR 12 Hull 8 TOU 15 DEF 2 Fort 10 Speed 4 (30 kph). Cable Vulnerability: Tow cable = Pilot vs Walker Pilot+Handling. Speeder is V vs W = 1 step up but maneuver: 1 deg = Vulnerable, 2 deg = Tripped (Fall Dmg 12 + crew Dmg 6 crit, 3 rnds prone).
Speeder Bike - V - Tier 4 Size -2, STR1 TOU8 DEF10 Handling +0 open (can target rider -2)
SCALE: P(0) < V(1) < W(2) < S(3) < C(4) < T(5)
UP (small->big): -5 Damage per Scale step. If ≤0, no effect. To-hit uses target's Size (Handling/Dodge) — big = easy.
DOWN (big->small): -5 To-Hit per Scale step, +5 Damage per Scale step. If -10+, save ammo. Then add target's Size Dodge: Small +2, Large -1.
Heavy ignores 1 UP. Point-Defense ignores 1 DOWN (to-hit only).
Penetrating 6 (lightsaber) works only P/V/W, not S+.
INSIDE SCALE — M&M Size:
Small (Ewok/Jawa): +2 Dodge/Parry, +4 Stealth, -2 Intim, Speed -5ft (Shrinking 4)
Medium (Human): +0
Large (Wookiee Growth 2): -1 Dodge/Parry, -2 Stealth, +1 Intim, +2 STR/STA (species already includes part)
Vehicle Handling IS its Growth Dodge penalty.
EWOK vs WOOKIEE vs AT-ST EXAMPLE:
AT-ST W vs P = -10 to-hit / +10 dmg
vs Ewok: Defense 16 (10+2 AGI+2 Dodge +2 Size) . AT-ST +4-10 = -6 vs 16 = need 22 = impossible (Ewok dives)
vs Human: Defense 14 . need 20 = 5% hit. If hit: Dmg 20 vs TOU 5 = DC35 = Dying.
vs Wookiee: Defense 13 (-1 Growth) . need 19 = 10% hit. If hit: Dmg 20 vs TOU 6 (STA+1) = DC35 vs 6 = Dying but +1 better.
PERSON vs AT-ST:
Blaster Rifle Dmg5 vs AT-ST TOU11: P vs W = -10 dmg = 0 = no effect for ANY P — Human, Wookiee, Ewok same gate. Need rocket Heavy.
But to-hit: AT-ST Defense 10 base +? Handling -2 + maybe 6 = 14? Ewok AGi higher? Same chance to hit the big thing — size bonus already in AT-ST Defense (easy to hit). So Wookiee and Ewok have same chance to HIT AT-ST, but Ewok is harder for AT-ST to hit back. Correct.
Examples: - "Can I lightsaber AT-AT leg?" P vs W = -10 = no. Joint exposed? GM: treat as V not W when Vulnerable. - "Can TIE shoot Luke on speeder?" S(3) vs P(0)=3 down=-15 to-hit +15 dmg. TIE +6-15=-9 vs Luke Def 18 (evasive) = need 27 impossible. Use strafe Burst. - "YT-1300 vs Victory?" S vs C=1 up=-5 dmg. Lasers 8-5=3 vs TOU15+Shields12=no. Torps 12 Heavy ignores 1=12 vs15=DC27 vs+15=needs12+. Victory vs YT: C vs S=1 down -5 to-hit +5 dmg. Vaporize if hits. YT must Evade+suppress turrets (turrets=S scale).
