Deadly Blow

# How it works

«Deadly Blow» is a melee attack skill, only with a dagger or dual daggers. Range 40, use time 1.08 seconds at «Atk. Spd.» 300 (faster as «Atk. Spd.» grows) plus another 0.72 seconds after the blow, cooldown 3 seconds, MP cost from 33 to 68.

At the start of the use a roll is made for the blow to land. If it fails or the target evades the physical skill, there is no damage, but MP, the cooldown and the soulshot are still spent. If it lands, the damage is calculated by the dagger blow formula, and the blow is always critical: there is no separate crit roll, critical power is already part of the formula.

A blow that lands can interrupt the target's spellcasting: a 10% chance multiplied by the target's cast interruption resistance; physical skills, dances and songs are not interrupted, and neither are raid bosses and invulnerable targets.

After the blow - whether it landed or not - a roll is made for a half-kill. An overhit on monsters is possible.

# Chance to land the blow

chance = 30% × «DEX» bonus × height bonus × 1.6 × skill and position multipliers

- height bonus: 1.1 at the same height; target higher than the attacker by 25 or more - × 1.3, lower by 25 or more - × 0.9, smoothly in between; - from the side × 1.1, from behind × 1.3; - target not in combat × 1.1; - skills that raise the chance of dagger blows: «Focus Death» × 1.6, «Critical Blow» from × 1.1 to × 1.3, «Mortal Strike» from × 1.1 to × 1.2, with enchant up to × 1.3; - enchant of «Focus Death» : chance up to × 1.7; - the dagger users' own buffs: «Exciting Adventure» × 1.3, «Wind Riding» × 1.2, «Ghost Walking» × 1.4.

The chance is never below 30% or above 80%.

Example: «DEX» 40 (bonus 1.20), face to face, at the same height: 30 × 1.20 × 1.1 × 1.6 = 63.4%. From behind: 63.4 × 1.3 = 82.4%, capped at 80%.

# Damage

damage = 77.08 × (power + «P. Atk.» × soulshot) / «P. Def.» × critical power × position × vulnerability to critical hits × attribute × PvP bonus + extra critical damage × 470.2 / «P. Def.»

- 77.08 = 70 × 1.10113 - the constant coefficient of physical skills; - the soulshot multiplies only «P. Atk.», not the power: × 2.04; - critical power is the same stat as for ordinary crits (buffs, sets, «Focus Death» : from the front × 0.7, from behind × 1.9); the cap is 15 with a dagger and dual daggers, 5 at the Olympiad; - «Focus Death» changes critical power by the position at the moment of the blow, while the damage position multiplier is taken at the moment of the roll; with enchant, critical power from behind goes up to × 1.95; - position: from the front × 1.1, from the side × 1.0, from behind × 1.2; the position is taken at the moment of the roll at the start of the use; - extra critical damage is the bonus from «Vicious Stance» , «Critical Power» , sets and weapon special abilities; 470.2 = 6.1 × 77.08; - in PvP: the attacker's PvP skill damage bonus multiplies only the main part of the damage, the target's PvP skill defense bonus multiplies «P. Def.» in both parts; - the enchant route's attribute and the target's vulnerability to critical hits multiply only the main part, they do not change the bonus from extra critical damage; vulnerability to daggers multiplies all the damage; weapon damage spread is usually ±5% (for most daggers), for some ±10%; - shield: on a block the shield's defense is added to «P. Def.», on a perfect block the damage is 1.

Example (numbers from real fights: «P. Atk.» 2 000, target's «P. Def.» 2 400, critical power 3.4, extra damage 706, skill lv. 37, power 5 479, soulshot, from the side): 77.08 × (5 479 + 2 000 × 2.04) / 2 400 = 307; 307 × 3.4 = 1 044; 706 × 470.2 / 2 400 = 138; total 1 182. From the front 1 286, from behind 1 391.

Damage from the side: «P. Atk.» 2 000, extra critical damage 706, soulshot

# Half-kill

After each use - both when the blow landed and when it did not - a roll is made for a half-kill:

chance = 10% × (1 + (skill magic level - target level) / 100)

- player: CP drops to 1, HP does not change; - monster: loses half of its current HP; - pet, servitor: half of its current HP; - other targets (guards and other NPCs that are not monsters): nothing.

The server rolls an integer from 0 to 99, so a fractional chance is rounded up: 9.4% is actually 10%, 10.5% - 11%.

It does not trigger on raid bosses and their minions, on doors, on targets protected from lethal strikes, on an invulnerable target and on a target more than 5 levels above the attacker. The skill has no instant kill.

Half-kill chance (calculated → actual)

# What protects

# Tested on the server

Checked against the PvP combat log from 05.10 to 16.10.2026: 1 279 landed blows from 22 characters, 1 117 of them with a full set of stats. The damage was recalculated by the formula above with the real «P. Atk.», «P. Def.», critical power and PvP bonuses of each blow.

# Specifics of our server

The skill's logic is close to the official High Five servers; the skill's numbers - power, the 30% chance, the 10% half-kill - are taken from their data. Nobody knows for certain how exactly the official server calculates a dagger blow inside, so on our server the rules are set explicitly:

1. The critical power cap with a dagger and dual daggers is 15 since 07.10.2026, before that 10; for most weapons it is 10, at the Olympiad 5 for everyone.
2. The roll for a half-kill is made on every use, even if the blow did not land.
3. Position for damage: from the front × 1.1, from the side no bonus, from behind × 1.2.
