Technocyte Coda Guide
A guide to the steps for defeating Technocyte Codas to acquire Coda weapons.
Coda weapons are not obtained directly upon vanquishing them, but instead are purchased from Eleanor in Höllvania Central Mall. They are sold in a similar manner to the Tenet weapons offered by Ergo Glast and can be exchanged for 10 Live Heartcells.
Live Heartcells can be obtained by vanquishing Technocyte Codas, with 10-15 being gifted to your inventory. Mercy on a Technocyte Coda Duet with Quick Correct equipped also has a chance to gain a Live Heartcell.
(The locations for obtaining Antivirus Mods and Potency Mods are written in the separate article.)
Prerequisites
You must have completed all main quests up to The Hex Quest to access Höllvania missions. Additionally, there must be no active Kuva Lich or Sister of Parvos, since you cannot have multiple active Adversaries simultaneously.
Coda weapons require a player to be MR17 or higher to purchase, but Live Heartcells and other items, such as Ephemera, can be collected regardless of MR.
Technocyte Coda Creation
Technocyte Codas are created by inserting a Mixtape, dropped by Techrot enemies in eligible missions, into a terminal and hacking it. The eligible missions are Exterminate, Hell-Scrub, and Legacyte Harvest in Höllvania, including bounties.
Unlike when creating a Kuva Lich or Sister of Parvos, it doesn’t matter what frame you use, and you don’t need to repeat missions until your desired weapon is selected.
Malware Disinfection
Once Malware Disinfection reaches 100% using Mercy with the correct Antivirus mod, you can proceed to the final showdown using Railjack.
Unlike finding the correct order of Requiem Mods, there is only one correct Antivirus Mod to look for. Since there are 8 Antivirus Mods and Parazon has 3 slots, you can find out the correct Antivirus Mod within three Mercy tries.
Technocyte Coda Duets spawn in the same missions that are eligible for their creation. However, once a eligible mission is completed, the same type mission will temporarily become ineligible as indicated on the Pom-2 map. Completing the five type missions or a successful Mercy on your Duet will make the missions eligible again.
Their appearance chance starts at 25%, increases by 25% for each eligible mission completed if they don’t appear, and drops back to 25% if they do appear.
There are two ways to increase Malware Disinfection:
・Mercy with the correct Antivirus Mod increases Malware Disinfection by 5%. This increase can be further amplified by equipping Potency Mods. The maximum increase from a single Mercy is 5+15+15=35% because Potency Mods will have no effect unless the correct Antivirus Mod is equipped.
・Completing eligible missions increases Malware Disinfection by 5%, excluding missions that already had an increase with Mercy. This way will not increase it from 95% to 100%.
Unlike Kuve Liches or Sisters of Parvos, the spawning of other players’ Duets does not directly impact your progress, although you can pick up items dropped by the effects of Potency Mods.
Mercy will not make your Duet level up, and as mentioned above, its appearance rate is unrelated to Mercy. Therefore, basically, there is no situation in which you should refrain from executing Mercy on your Duet.
If I had to say, the only exception would be when you came to a mission with too many Potency Mods equipped. For example, in a case where your Malware Disinfection is 85%, you can reach 100% with the correct Antivirus Mod and one Potency Mod. Nevertheless, if you have two Potency Mods equipped, both Potency Mods will lose one charge although the effects of additional resource drops will work.
Final Showdown
The Railjack mission is primarily small scale Hive and Exterminate in the ship, and all that is required of Railjack itself is to simply move and destroy two speakers. For the latter purpose, Shatter Burst is effective.
During the phases where you just need to avoid stage attacks, it is easiest to wait using invincible frames, such as Nyx, Valkyr, and Revenant.
During the fight phases, defeating only the Frontman will not be enough, as he will regenerate, so you must defeat all the members. High-damage AoE attacks, such as Voidrig’s 4th ability, are highly effective.
Increasing the number of squad members will only increase the number of fights, but will not provide any additional rewards. It’s more efficient to tackle it solo.
After the final Mercy, you don’t necessarily have to use the Esophage to return; you can warp aboard the ship using Omni gear if you have unlocked the Rank 4 Tactical Intrinsic.
Grind Calculation
To obtain all 13 Coda weapons with 60% progenitor bonus using 1 Valence Fusion each, 260 Live Heartcells are required. According to the expected value, this is equivalent to 21 Coda kills, or 32 kills if using 2 Valence Fusions each.
In the former case, one of the two needs to be at least 52.8%, while in the latter case, one of the two used in the first Valence Fusion must be at least 48.0%.
To collect all 14 items (8 Ephemera, 5 Emotes, 1 Capture Scene) without trading, the expected number of trials is approximately 45.5. Even if aiming to only collect the 8 Ephemera, this number is still approximately 38.
