Attack

An attack is any action intended to cause harm to its target; popular choices include punching, kicking, or shooting them in the head.

There are two main types of attacks: unaimed attacks and aimed attacks.

Unaimed attack

Unaimed attacks, a.k.a. normal/basic attacks, that do not target any specific body part. They use your base hit chance and critical chance values, and will always land on the target's torso.

To perform an attack, you must select a valid target.

In FOnline, same as in Fallout 1 and 2, target selection is separate from aiming, however, the latter referring specifically to a deliberate attempt to hit a particular body part (see below).

Aimed attack

An aimed attack is a deliberate attempt to hit a specific part of your target's body.

Aiming imposes a hit chance penalty on the attack, doubles its attack delay, and increases its AP cost, but in return grants bonus critical chance that scales with Luck.

The table below shows the hit chance penalties, AP cost increases, and base critical chance values associated with the body part being aimed at.

Body part	Hit chance	Base critical chance	Additional AP cost
Eyes	-60%	60%	+2 AP
Head	-40%	40%	+2 AP
Groin	-30%	30%	+2 AP
Arms	-30%	30%	+1 AP
Legs	-20%	20%	+1 AP
Torso	-0%	0%	+1 AP

For most characters, aiming for the torso makes no sense as it activates the AP cost and attack delay penalties with the only "benefit" being the attack type changing from unaimed to aimed.

All aimed attacks have their base critical chance multiplied by 20% and a Luck-scaling critical chance bonus with the base value of 4%. This base value can be increased by the Marksman perk synergy and the More Critical level perk.

The final bonus critical chance granted by aiming an attack is calculated as:

Final Bonus Critical Chance = Base Critical Chance x {20% + [(4% + Marksman bonus + More Critical bonus) x Luck]}

Examples

The following examples demonstrate how the bonus critical chance from aimed attacks is calculated under various conditions:

• If a character has Luck = 20 and aims for the eyes (60% base critical chance):
  60% × {20% + [(4%) × 20]} = 60% × {20% + 80%} = 60% × 100% = 60% bonus critical chance.
• If a character has Luck = 20 and the Marksman perk synergy (+3%) and aims for the eyes:
  60% × {20% + [(4% + 3%) × 20]} = 60% × {20% + [7% × 20]} = 60% × {20% + 140%} = 60% × 160% = 96% bonus critical chance.
• If a character has Luck = 20, the Marksman perk synergy (+3%), and the More Critical level perk (+1%) and aims for the eyes:
  60% × {20% + [(4% + 3% + 1%) × 20]} = 60% × {20% + [8% × 20]} = 60% × {20% + 160%} = 60% × 180% = 108% bonus critical chance.
• If a character has Luck = 1 and aims for the legs (20% base critical chance):
  20% × {20% + [(4%) × 1]} = 20% × {20% + 4%} = 20% × 24% = 4.8% bonus critical chance, rounded up to 5%

Attack delay

Attack delay is the minimum time (in milliseconds) that must pass after an attack before any action can be performed.

The lower your attack delay, the faster you are. Each weapon has its own base attack delay value and, as of Patch 6.3.5, so do items that restore hit points.

The table below lists various modifiers that affect attack delay. Bonuses reduce delay (good), while penalties increase it (bad).

Type	Modifier	Source	Notes
Bonuses	-200 ms	Fast Attacks (level perk)	Flat reduction
	-20% (-50% for Regulator)	Fast Shot (trait)	Applies to single shots only; does not affect rockets/flamers
	-5%	Attack Speed (AS) (WE stat)
	-5%	Melee Mastery (S.HTH) (WE stat)
	-40%	Cowboy (level perk)	Limited to pistols
	-50%	Quick Fingers (perk synergy)	Single shots only (excluding melee and throwing attacks)
	-10%	Soldier (class perk)	Limited to Support Rifles
	up to -20% (-35% for Hubologist)	Bonus Attack Speed (weapon perk)	Varies by rank
	-0.5% per Leader's Charisma	Leader's mobility flags	Scales with Leader's Charisma
	-1% for each point of Luck	Bounty Hunter (class perk)
	-10% (random chance)	Random Boy rolls	Unlucky roll applies a +3% penalty instead
Penalties	+100%	Aiming
	+2% per stack	Slow stacks
	+1% for each point of Charisma	Priest (class perk)
	+25%	Raider (class perk)
	+3% (random chance)	Random Boy rolls	Lucky rolls apply a 10% reduction instead
	+30%	Target has Quick Recovery	Applied when attacking a target with this level perk
	+0.5% for each point of Intelligence	Intelligence

Special cases

• Wrecker's attack delay depends on how far the target is: it starts at 100ms if the target is on an adjacent hex and increases by 100ms more for each extra hex
• Heresy sets the minimum attack delay to 1200ms
• Killer's rage sets Killer's attack delay to 700ms for 10 seconds

Strike

The attack that starts your battle timer ("Strike") may benefit from an extra effect depending on your class.

Most classes have no special ability associated with initiating combat but those that do often rely on it heavily; for example, Combat Master's strikes allow the class to teleport right to the target from up to 40 hexes away to deliver a powerful surprise attack.
