Silva & Aegis Prime is the Primed variant of the Heat-based Silva & Aegis sword and shield. It has increased damage, critical chance, critical multiplier and status chance, but significantly slower attacks, and like the original it gains bonus crit and status chance when blocking.
Blueprint and parts drop from Void Relics that you open in Void Fissure missions; the relic list on this page shows the exact relics. Block incoming hits to charge its bonuses and counter with the heavy, slow strikes.
Silva & Aegis Prime was added with Hotfix 20.6.2 (May 2017).
Requires Mastery Rank 12.
Silva & Aegis Prime is currently in the Prime Vault.
