+> While writing this, Requiem and I faced a bit of a challenge concerning death rate calculations. Case in point is the passive "Item Construction" +and its interaction with Instant Kill, as we could not reach a final verdict if it affects Instant Kill Hit rate or not. In case of this article, I will assume +it doesn't interact with the hitrate, but if you have proof that this is different, I will gladly incorporate this in the article. + +## Introduction + +Instant Kill & Instant Death: One of the most rejected systems to exist in FGO. Most players know of it, but discard it because of its unreliability and uselessness against stronger enemies. In this article, I want to dive a bit into the workings of Instant Kill and help you understand how you can, in specific scenarios, use it to your advantage. + +There are a multitude of servants that have access to instant-kill, but I will only highlight a few here (You can view the full list on Gamepress) + +- **Nitocris (Caster)**: The most prominent figure, as she has easy access to her instant-killing NP and a skill that increases her death hit rate +- **Void Shiki (Saber)**: Another Example of an AOE Instant-Kill servant who also has access to Death Resist debuffs. One quest in her release event even specifically used the Instant Kill mechanic (Quest Link here) +- **King Hassan (Assassin)**: The only servant that can afflict enemies with instant death on normal attacks (Note: David can do this as well, but only if he has his Bond CE equipped) + +But since Instant Kill is based on probability, most players are relucatant to use it in their farming compositions. This thems from the different death rates enemies have: + +- Bronze: 80% +- Silver: 50% +- Gold: 20% + +This list here is just for rarities. However, there are a lot more factors to consider, as some enemies have higher death rate, some lower. Be sure to check each case individually, as rates may vary. + +Also, servant enemies usually have a death rate of 0.1%, sometimes a bit more like 0.3% or 0.4%. So going for Instant Kill on servants will, in the majority of cases, not work. + +## Calculating Instant Death Rate + +The formular for getting the probability of an enemy dying to Instant Kill is as follows: + +``` +death = hitRate * deathRate * (1 + instantDeathRateUp - instantDeathRateDown - instantDeathResistUp + instantDeathResistDown) +``` + +The parameters here are the following: + +- `hitRate`: The Death Hit rate of the effect or NP used +- `deathRate`: The Enemy Death rate +- `instantDeathRateUp`: Buffs that increases instant kill success rate (Nitocris S1) +- `instantDeathRateDown`: Debuffs that decreases instant kill success rate +- `instantDeathResistUp`: Buffs that increases instant kill resistance (Taira S2) +- `instantDeathResistDown`: Debuffs that decreases instant kill resistance (Void Shiki S1) + +## Example + +The main reason this came up was because of a farming comp used in Hunting Quest XI - Day 5 - Pride+. The node is structured +into a 2 - 1 - 1 Layout, meaning using a dual-DPS setup would be the way to go. + +Looking at the stats for the first wave, it made sense to use Nitocris: Both Ghouls have a 100% Death Rate according to Atlas Academy. + +I went with using Nitocris, since she has a 100% NP charge and a skill that increases her Instant Death rate by 100%. Not needing any additional charge meant that no other buffs or AOE charges needed to be used on turn 1. + +Her kit brings the following stats: + +* Her NP has an Insta-Kill Hit Rate of 50% when used at Overcharge 1 (meaning 100% charge) +* Her S1 increases Insta-Kill success rate by 100% + +### Actual calculation + +When using the formular from above, we have the following values + +``` +hitRate: 50% +deathRate: 100% +instantDeathRateUp: 100% +instantDeathRateDown: 0% +instantDeathResistUp: 0% +instantDeathResistDown: 0% +``` + +This means we can fill in the formular like this + +``` +death = 0.5 * 1 * (1 + 1 - 0 - 0 + 0) +``` + +We now break everything down step by step + +``` +death = 0.5 * (1 + 1) + = 0.5 * 2 + = 1 + = 100% +``` + +So her death succeeds 100% of the time on these ghouls, which makes her perfect to use in this scenario. + +For other skill levels, this looks like this (_Her S1 scales from 50% to 100%_) + +``` + Skill Level | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 +-------------|-----|-------|-----|-------|-----|-------|-----|-------|-----|------ + Death % | 75% | 77.5% | 80% | 82.5% | 85% | 87.5% | 90% | 92.5% | 95% | 100% +``` + +In the end, this resulted in the following comp that worked like a charm. + +
+ +
+ +## Conclusion + +This small article should have given you an insight into using Instant Death as an advantage in the future. But remember: Stacking Gacha in a Gacha game can backfire. + +That's all for now, thanks for reading +~ Firq \ No newline at end of file
