Superior Gold Plated Primordial Sword

[Surzie]

What is the evolution chain for this one? I have Superior Gold Plated Sword level 100, how the heck do I get a Superior Gold Plated Primordial Sword?

All primordials are based on kill count not no level. You need to reach 42k kills on the highest "version" of the reaper, reduced by affinity. (100 affinity halves the requirement)

[Peredur]

Evolution is based on level reached. Not all Slorm Reapers can evolve (there is a grey line joining the next Reaper to show it can evolve).
Unlocking of the Primordial version is based on the number of kills. All Slorm Reapers have a Primordial version.
Those are two different things.

To be noted:
- number of kills to unlock the Primordial version is around 42k but it can be reduced with Repear Affinity (down to 25% of that).
- kills on all evolutions of a same Reaper contribute to the unlocking of the Primodial version (but last kill may have to be done with the most evolved one)
- on unlock of the Primordial version of a Reaper with evolution, only the first evolution is unlocked and you have to level the Primordial version through all evolutions
- there is one case of special evolution, Aurifurious, needing to get two Reapers to evolution level (50) in order to get their evolved version
