Decussation (ユニゾンクロス, Yunizon Kurosu?, lit. "Unison Cross") is a technique that appears in Kingdom Hearts 3D: Dream Drop Distance. It allows the user and their Spirit to repeatedly teleport around an enemy and slash at them.
Decussation is a Link Attack that drains the Link Gauge by 6.6% per second. Pressing lets the user and Spirit execute an attack that costs 10% of the Link Gauge and deals Physical damage. When the Link Gauge has 10% or less remaining, pressing lets the user and Spirit perform a diving thrust that deals Physical damage and generates a shockwave on the ground, which deals Physical damage when linking with a Chef Kyroo or Sir Kyroo, Thunder-elemental damage when linking with a Lord Kyroo, and Fire-elemental damage when linking with a Ryu Dragon.
