Drain/G
It is a common misconception that the Drain Gummi draws in orbs, but this is false. Drain/G is indeed a weapon, but it is a bit complicated. How to control it depends on your auto-fire settings in the menu; the following is the default. Hold down X to begin absorbing incoming normal (red) projectiles. When fired by releasing X, its power comes from those projectiles. This makes it a very powerful weapon if used correctly, especially for enemies such as the Final Hunter on mission 27.
