Last slot is for either [Netra Invocation] (for efficiency), [Ris Invocation] (for duration) or [Vome Invocation] (for strength).
For pure DPS eg against murmur in EDA, can swap [Xata Invocation] for [Anemic Agility]

Use external fire rate buffs like [Reinforced Bond], [Furax Wraith] with Amalgam [Body Count], [Afentis] or Arcane Velocity if you want to use [Noctua] for DPS too.

Wordwarden ignores fire rate and multishot.
