Part 2 of the Lich/sister guide
I don't want to go too much into detail but you might wonder which bonus element you actually would want on your Kuva and Tenet weapons.
The bonus element you get depends on the Progenitor Warframe you used to get the Kuva Larva or the Sister.
Impact | Baruuk • Gauss • Grendel • Rhino • Sevagoth • Wukong • Zephyr |
Heat | Chroma • Ember • Inaros • Nezha • Protea • Vauban • Wisp |
Cold | Frost • Gara • Hildryn • Revenant • Titania • Trinity |
Electricity | Banshee • Excalibur • Limbo • Nova • Valkyr • Volt |
Toxin | Atlas • Ivara • Khora • Nekros • Nidus • Oberon • Saryn |
Magnetic | Harrow • Hydroid • Lavos • Mag • Mesa • Xaku • Yareli |
Radiation | Ash • Equinox • Garuda • Loki • Mirage • Nyx • Octavia |
But what is a good choice?
Well that highly depends on the weapon and on what you want to do.
Good choices are Heat, Toxin, Radiation, Magnetic and on rare occasions even impact.
Impact is a good choice if you have a weapon that already has impact damage and you want to push the value even higher in order to use Hemorrhage or Internal Bleeding to apply slash procs when doing impact damage.
For most weapons Toxin is a good choice since you can simply add a Cold mod to get viral damage which is pretty strong.
If the weapon already has innate Heat damage you most defintely do not want to put a Toxin on it beause Heat + Toxin = Gas and you won't get rid of this combination anymore unless you waste mod slots.
A good bonus damage for such a weapon with innate Heat would be Magnetic or Radiation. Magnetic is very strong against shielded enemies such as Corpus and bosses. Radiation damage is good against Alloy armor of high-lvl Grineer or Corpus Robotic enemies. You have to make a choice here.
The good part is that Magnetic and Radiation are cobinations of two lower elemental damages. So you will need one less mod slot if you were going to mod your weapon for these elements.
e.g. the weapon has Heat as innate damage type and you put on Magnetic as bonus damage you will have Heat + Magnetic without any mods. Now you can put on a Toxin mod and a cold mod to get Viral.
That means with just 2 mods your weapon will have 3 status types (Heat + Magnetic + Viral). With the new Galvanized mods or Condition Overload you get bonus damage per status type... making these weapons even stronger (just by carefully selecting the bonus damage on your weapon).
What happens if you do not follow this advice?
Let's assume again you have a weapon with innate Heat.
example 1:
You put another Heat as bonus damage. Now you add the Toxin + Cold mods.
This results in Heat + Viral -> only 2 status types the Galvanized mods/Condition Overload can use to produce damge.
example 2:
Again Heat is the innate damage of the weapon and you add Toxin. We also add Toxin + Cold mod.
Heat + Toxin turns into Gas and the Toxin + Cold turn into Viral.
Result: Gas + Viral
Not the best combination and again only 2 status types.
example 3:
As before Heat is innate damage type of the weapon and you add Elextricity as bonus damage. Cold + Toxin mod.
Heat + Electricity = Radiation and Cold + Toxin = Viral.
Two good combinations but still only 2 status effects.
My advice is to take a look at the innate damage types of the Kuva and Tenet weapons. Make a spreadsheet and decide which bonus damage type you want before you even start grinding for the weapons. Use the progenitor table above to spawn the weapon with the desired bonus damage.
