Critical hit

In Critical Hit FOnline3 have a few terms like:

• Critical Roll
• Critical Power
• Critical Chance
• Aimed Attack
• Critical Chance Resistance
• Critical Roll Resistance
• Critical Power Resistance
• Critical Effect
• Critical Damage
• Critical Table
• Aggressive Implant
• Critical Tier

Critical Power and Critical Roll

Difference between Critical Power and Roll is very simple, the Critical Power is % multiplier of Critical Roll, which is our base of Critical Hit.
Critical Roll sources:

• Base Class Perk Critical Roll if non-class is 0-5
• War Event Stat: 10
• 1 per Luck
• Random Boy Roll: -90 to 90
• Cyborg 1 per Luck
• Cyborg 4 per Charisma when 3 Aggressive Implant
• Slayer synergy: 10
• Voodoo: 10
• Better Critical: 10
• Combat Master 1 per Strength
• Combat Master 5 per Fury
• Bounty Hunter 1 per own Critical Chance
• Bounty Hunter 1 per target Critical Chance
• Bounty Hunter 1 per 10 Sight Range
• Soldier: 1
• Sniper 1 per distance from target(doubled if Long Range

Critical Power sources:

• 100% as base
• War Event stat: +10%
• War Event target defensive stat: -15%
• Mastery of Perception: +20%
• Heavy Handed: -20%
• Better Critical: 25%
• HtH Better Critical: 33%
• Silent Death effect: 10%

so right now our Critical roll on end is roll*power but its not all!

Critical Resistances

In FOnline 3 we have 5 different critical resistances:

• Armor Critical Chance Resistance
• Armor Critical Power Resistance
• Critical Chance Resistance
• Critical Power Resistance
• Critical Roll Resistance

Let's start with Armor Critical Chance Resistance and Critical Chance Resistance, both working same way and stacks with each other but there is one difference between them: way how to bypass it! Armor or Helmet Critical Chance Resistance can be bypassed by Hit The Gaps 80% for armor and Right Between The Eyes 90% for helmet. For Other Critical Chance Resistance can be bypassed by Plasma Damage or in case Armor Perks can be bypassed by Bounty Hunter Source of Critical Chance Resistance:

• Fill The Gaps: 20%
• Anty-Crit: 30% vs NPC
• Leader: 50%
• Mastery of Strength: 35%
• Man of Steel: 25%
• Bonehead: 25%
• Iron Man Synergy: 30%
• Cigarettes: 5%
• Cyborg 1 per Charisma when 3x Dermal Impact Armor

Aggressive Implant Decrease sums of armor and other Critical Chance Resistance by 15% for each implant

Now Critical Power Resistance and Armor Critical Power Resistance, same as chance only difference is how to bypass it, Armor Critical Power Resistance can be bypassed only by Slayer Synergy 80%
Critical Power Resistances working in simple way it just decrease % of opponent Critical Power Example: opponent have 60% extra Critical Power, you have 25% resistance, 60 - 25 = 35
Sources of Critical Power Resistance:

• Mastery of Strength: 25%
• Deathclaw: 20%
• Bonehead: 50% (bypassed by Plasma Damage)
• Cyborg 1% per Charisma when 3x Dermal Impact Armor (bypassed by Plasma Damage)
• Man of Steel: 50% (bypassed by Plasma Damage)
• Iron Man Synergy: 30% (bypassed by Plasma Damage)

Aggressive Implant Decrease Critical Chance Resistance(not from Armor) by 15% for each implant

Last Critical Defense is Critical Roll Resistance, it just decrease opponent Critical Roll before apply Critical Power
Sources of Critical Roll Resistance:

• Heavy: 20 (bypassed by Bounty Hunter)
• Anty-Crit: 60 vs NPC(bypassed by Bounty Hunter)

Summary our Critical hit is ( Critical Roll - Target's Critical Roll Resistance ) * ( Critical Power - Target's Critical Power Resistances)

Critical Effect

In FO3 we have 10 different Critical Effects which can be applied when your total Critical Roll reach a Critical Tier which unlocks that effect, for example: we reach tier 3 critical in eyes so we have chance to apply Slow, Knockdown or confusion, all effect can applied together.
Chance to apply Critical Effect is 33% it can be increased by:

• Finesse 33%
• Alien Set to 100%

Critical Effects and possible defensives:

• Slow put decrease 20% of Movement Speed, 1% less for target's Intelligence and 2,5% less if target took Mutie
• Knockdown -3 Action Points for target, if target have Quick Recovery it reduce to 1, if target's have Stonewall can resist knockdown 8% per Strength
• AP Drain 2-4 Action Points are taken from target to attacker
• Weapon Drop drops target weapon, Iron Limbs gives immune for it
• Death Effect extra 100 damage which bypass any defense
• Knockout -10 to 30 Action Points for target, amount of AP decrease target's Agility and /3 if Quick Recovery, Knockout can be resist by Stonewall 7% per Endurance
• Bypass Reduce half of target's DR and all DT
• Weapon Destroy decrease target's weapon deterioration by 1-25%
• Confusion decrease Target's Sight Range by 2 hexes
• Criple broke leg, hand or eye, can be immune by Iron Limbs

Critical Table and Critical Tier

Critical Roll - Target's Critical Roll Resistance ) * ( Critical Power - Target's Critical Power Resistances gives us a number which we can fit with table below but if we have Critical Tier up just look on next tier
Critical Table from Patch 4.96.45
