note on silent strike

New page

The ability to hit an aimed location depends on skill training and other factors. For melee attacks, [[Combat Maneuvers]] and [[Ambush]] skills are needed. For ranged attacks, [[Perception]] is the main factor when firing in the open, and Perception and Ambush are weighted equally for hidden sniping. For Limb Disruption (708), [[Spell Aiming]] is used for targeting limbs.

==[[Verb:AIM|AIM (verb)]]==
This is the help menu for the verb {{boldmono|AIM}}. For details on verb usage, please see [[Verb:AIM]].
{{#section:Verb:AIM|verb}}

== Roundtime (melee weapons) ==
{{main|Base weapon speed}}
Whether one is attacking from hiding or in the open, aiming adds three seconds to an attacker's weapon BASE [[roundtime]]. This additional roundtime may be mitigated in the normal way via [[agility]] and [[dexterity]] bonuses down to the ''minimum aimed roundtime'' of the particular weapon used. The minimum aimed roundtime of a weapon differs from the normal minimum roundtime of that weapon as follows:

{| {{Prettytable|text-align:center;}}
|-bgcolor=lightblue
!Weapon base speed
!Normal Min. RT
!Min. Aimed RT
|-
| 1
| 3
| 4
|-
| 2, 3
| 4
| 5
|-
| 4+
| 5
| 6
|}

== Other Limitations ==

Any condition that prevents a character from attacking normally will prevent this verb from working, as will attempting to aim at a nonexistent (''e.g.'', the legs of a worm) or already severed body part.

Size disparity can also prevent aiming at specific body parts. Large [[character]]s will not be able to aim at specific parts of small critters (''e.g.'', a [[human]] cannot aim at specific parts of a spiked cavern urchin). Furthermore, no character can aim at a part of a [[creature]] that, because of size limitations, is out of his or her reach (''e.g.'', a [[dwarf]] cannot aim at the head or neck of a [[giant]] that is standing up). The use of longer weapons can somewhat mitigate this.

== Success and Failure (melee weapons) ==

The factors that influence the chance of successfully attacking the body part aimed for include:
* difficulty of the particular body part targeted (smaller and more critical parts of the body are harder to aim for)
* the difficulty modifier for the weapon used (larger weapons are harder to aim)
* difference in attacker and target [[level]]
* the attacker's [[Ambush]] skill
* the attacker's [[Combat Maneuvers]] skill (when aiming from the open, as opposed to from hiding)
* any eye or bleeding head [[wound]]s the attacker may have
* formula for aiming success: [[Aiming Success]]

Failure to hit the desired body part will result in attacking a different part of the target's body, or, at low skill levels, may result in the attacker being unable to find an opening for an attack yet still incurring roundtime.

== Aiming Formula: Melee and Hurling ==

An initial d100 is made. If you roll <= 5, you auto fumble. If you do not auto fumble, the d100 roll is used in the skill check:

MIN(95, ('''Skill''' + '''Stats''' + '''Weapon Modifier''')/2) + '''Area modifier''' + '''Target Status''' + d100 = '''Result'''

Note: Level is not taken into account for aiming success chance. A comparison between Target size and attacker size is included in the area modifier.

[[Silent Strike]] reduces aiming chance by 50% at rank 1 and scales down to 10% at rank 5 (10% per rank).

==== Result ====
> 100: Success
<100 and >66: you miss the location but still find an opening to attack
<=66: You fail to find an opening

==== Skill ====
Melee
: Aiming from hidden = Ambush Bonus
: Open aiming = TRUNC((CM Bonus + Ambush Bonus + 1) / 2)
Hurling
:TRUNC(TRUNC((cman + ambush + 1) / 2) * (3 / 2))
:Effectively the same as Melee * 3/2

==== Stats ====
Melee
: Dex Bonus + TRUNC((Int Bonus + 1) / 2)

Hurling
: Int bonus + TRUNC((Dex Bonus + 1) / 2)

==== Weapon Modifier ====
Varies based on weapon. Large/slow weapons have more penalty. Small and maneuverable weapons have a bonus.

Table added at the bottom of the page

==== Area Modifier ====
Head: -10
Neck: -15
Arms: +10
Legs: +15
Hands: +5
Eyes: -25
Other: 0

*[[Predator's Eye]] adds into the calculation as part of the location modifier.
*The area modifier is also modified by attacker/target size. Attacking a target bigger than attacker is easier, a target smaller than attacker is more difficult.

==== Target Status ====
Kneeling/Sitting/Prone: +10 if head/neck/eyes, +25 otherwise.

==== Example ====
202 CM + Lance (-50 aim) aiming at the head,

d100 = 84
Skill = ((302 + 0 + 1) / 2) = 151
Stats = (20 + (22 + 1) / 2) = 31
Attacker modifier = 0
Weapon Modifier = -50

Result = MIN(95, (Skill + Stats + Weapon Modifier)/2) + Area + Target Status + d100 = MIN(95, (151 + 31 - 50)/2) - 10 + 0 + 84 = 140
140 > 100 = Success

== Aiming Formula: Ranged ==

Below is copied from Discord, formatting to come:

<nowiki>
d100, <= 25 automatic failure
rolling a 1 is a major fumble and shot flies wide of the target, otherwise you just miss your locaton

Base Skill:
Hidden = TRUNC((Perception Ranks + Ambush Ranks) / 2) + TRUNC(Ranged Weapons / 4)
Open = TRUNC(Perception Ranks / 2) + TRUNC(Ranged Weapons / 4)

Location Penalty:
Head: 10
Neck: 12
Limbs: 2
Hands: 5
Torso: 2
Eyes: 20

Penalty = ((3 * Target Level * Location Modifier) / Base Skill)

Target Status:
Prone/Sitting: -10

Size Mod (target):
Tiny: -10
Small: -5
Medium: +5
Large: +15

Spells (on attacker):
607: -20
613: 15 + (Ranger ranks over 13)
404: +5
412: -10
1001: -10

Crossbow:
Standing: +5
Kneeling: +20

+sighting

> 100 = Success
>= 50 minor failure, missed location but shot succeeds
< 50 major failure, shot flies wide of the target

Example: 2x perception + 2x ranged firing from open at left eye. Target is level 100 and normal size (0 modifier)
d100 = 50
Base aim skill = TRUNC(202 / 2) + TRUNC(202 / 4) = 151
Left Eye penalty = ((3 * 100 * 20) / 151) = 39
Area adjusted skill = 151 - 39 = 112
Sighting = 0
Final skill = Adjusted Skill + d100 = 112 + 50 = 162 > 0 = success
