The Best Jade Builds In Warframe

I'm trying to evolve the Laetum, and have the strun and skana incarnon equipped But it didn't register after doing a solo mission

every slot, so can't do this till you have atleast 3, but thats not the weird part, it says

complete mandatory slot 1 in swiggy means The fifth and final Evolution is unlocked by equipped an Incarnon weapon in all three weapon slots At the moment, there is only one

slot via qris Evolution II: Complete a solo mission with this weapon equipped Perk 1: Swift Conclusion: Increase Damage & Increase Damage by +200% if enemy
