Subsume Xata's Whisper and use a Kubrow with Mecha Recharge and Mecha Overdrive to complete the build. Use with my Desert Wind build and stat-stick Redeemer Prime build - build up to 12x combo with a few hits from [Redeemer], then switch to [Desert Wind] and hit only with the waves (not directly with the melee attack) for hundreds of thousands or possibly millions of damage. Optionally use Naramon with maxed Power Spike and add Primary Dexterity/Secondary Dexterity arcanes to your weapons for the longest combo duration possible.
