For use vs Orphix "Resonators" (the pylons they spawn).

Riven replaces [Sabot Rounds] if Total Damage (excluding crit) is above 5000 (excluding Multishot), otherwise it replaces Automatic Trigger.
This means that if the Riven has +3 with no neg, or non-high roll with a neg you'll need to replace [Automatic Trigger]. But for any other combo containing Damage or ElementalDmg you can replace [Sabot Rounds].

Riven Stat priority: Multishot > Damage > Elemental
