Flexible/Alternatives:

• Primed Cryo Rounds - Rime Rounds is more accessible and provides more consistent viral procs which boosts slash proc damage
• Critical Delay - Point strike provides slightly less CC without fire rate drop, still keeping below the 2.5 threshold for Internal Bleeding
• Primed Firestorm - swap for serration, hammershot or bladed rounds
• Primed bane of grineer - swap for normal bane or [Serration] if you absolutely [Hate] banes

Note serration has been dropped due to primary merciless. If you do not own primary merciless, you can add serration/[Amalgam Serration] over [Primed Firestorm] or [Vile Acceleration].
