Sometimes, devs post those values on these forums, but it's pretty sporadic and not complete, even remotely. Many such replies are already outdated.
To get some values, it's necessary to read a lot of forums posts, including changelogs.
This.
I'd love for us to have a good census of this. I once gathered up a list of them about 4 years back. Maybe I'll do it again when I have the time and put it in the Wiki so it would be easier to track.
Just to get you started with estimates:
E11: Primary 26 (might be 28 at lvl3), Secondary 24
Clone Rifle: 20(ish, might be 22 or 24 at most)
T21: Primary 60(ish), Secondary 30
A280/DLT20a: 28
Clone Pistols: 28 (charge only increases amount of bounces, no dmg boost)
Westar Pistols: 26 (might be 28) (fully charged deals about 3-4x)
Projectile Rifle: 150
Disruptor Rifle: 30 -> a slight curved charge function with 150 max dmg
Bowcaster: 40(ish), fully charged deals about 3-4x
EE3: Unscoped 28, Scoped 100
Westar M5: Unscoped 24, Scoped 60(ish)
SBD: 30(ish, damage might still depend on amount of battery)
Standard Pistol: 26 (fully charged max damage is approx 4x)
Pistol 3: 40(ish, fully charged max is approx 4x)
Droideka: 30(ish)
Frag Grenades/Rockets: Base damage 150(ish), degrades towards the edges
Thermal Detonator: 400(ish), degrades towards the edges, a wookiee with Health 3 can survive
Each weapon has a unique Force Drain multiplier applied to them when dealing FP damage.
Weapons that scale extra well relative to their base damage:
- Westar M5
- Pistol 3
- Clone Pistols
- Westar pistols
- Droideka
Generally anything at 28 or above base damage will deal a heavy impact to FP. Anything below will feel much lighter.
Rate of fire approximation:
- Droideka Firepower 3
- Clone Rifle 3, SBD Firepower 3
- T21 secondary, E11 secondary, Clone Rifle 2, Westar 3, Clone Pistol 3, Bowcaster 3, SBD Firepower 2, M5 noscope
- A280, DLT20a, E11 primary, EE3, M5 scoped, Clone Rifle 1, SBD Firepower 1
- Bowcaster 1-2, Pistol 1-3
There is a general rule of Steady Shot which means you are accurate when walking/crouching/standing:
- E11: Steady shot, average spread when running, Level 2 secondary fire always spreads
- EE3: Non-sniper mode's first 2-3 shots always accurate, then accuracy degrades per shot, sniper mode has steady shot that is also applied when mando is "standing" while flying
- Westar M5: Level 1 steady shot, level 2 always accurate. Scoped is steady shot, with the exception of Dexterity 3 giving it perfect accuracy while performing acrobatics
- All pistols: Always accurate
- Bowcaster: Steady shot
- T21: Only accurate while standing still
- Clone Rifle: Only accurate while standing still
- Droideka: Always accurate
- SBD: Steady shot
- Disruptor: Always accurate
- Projectile Rifle: Only accurate while standing still
- A280: Level 1 only accurate while standing still, Level 2+ steady shot
- DLT20a: Only accurate while standing still
Generally the accuracy spread is pretty heavy duty. Generally the slower you move, the more accurate you are. Some weapons are surprisingly accurate while running (Bowcaster 3, Clone Rifle, T21)
Location damage multipliers are roughly as follows:
- Head: 3x
- Chest: 2x
- Arms: 1.25x
- Waist: 1x
- Legs: 0.75x
Hope this helps a bit.
