Invisible Weakening of a Drained Power

It's up to the GM how he wants to describe it. But at the very least it should be obvious to the character that his attack had no effect. What information the GM provides, and how the player interprets that information (wrong SFX, too much Power Defense, he's secretly Desolidified, whatever), is something the rules have no control over.
This was in response to whether an Adjustment Power, such as Drain, obviously had no effect on a target.

My question is, what should a character take to make it look like his power is unaffected by an Adjustment Power, even if it really has been affected? Is this a form of Invisible Power Effects?

That's up to how the GM wants to interpret special effects. Some people would be content to use that explanation for Power Defense. Others might want the character to buy some sort of Images construct. Start a thread on the "Discussion" board and you'd probably get plenty of other ideas. It's not IPE, though; that has to do with making powers unperceivable, not with changing their appearance in the face of outside effects.
