Drain Dive (ドレインダイヴ, Dorein Daivu?) is a technique that appears in Kingdom Hearts 3D: Dream Drop Distance. It allows the user to jump into the air, then dive downward and create a shockwave that drains HP from nearby foes.
In Kingdom Hearts 3D: Dream Drop Distance, Drain Dive is an attack command that uses one slot in the Command Deck, and has a reload time of 20 seconds. It grants +10 to HP and +1 to Defense when attached to a Dream Eater recipe.
