Diminishing returns function by a multiplicative factor - they are indeed the effect of multiplication. If something lowers armor by 75%, it multiplies the armor by a factor of 0.75 each time it's applied. This means it will have diminishing returns, because while the first dash grants an entire 75% reduction of base, subsequent dashes will scale the armor down by the same factor relative to remaining armor, rather than by a flat subtraction of a set amount of armor or by removing a percentage of the base armor.

If an enemy starts with 1000 armor, one dash drops it to 250, which is a reduction of 750 armor. A second dash will drop its armor to 187.5, which is a reduction of 62.5 armor, which is far less of a reduction than the first dash, while still being a 75% reduction of armor relative to its current armor, rather than its base starting armor. This is a diminishing return due to a multiplicative effect.

Unless I'm misunderstanding what you mean here. "Diminishing returns" just means that the flat amount of armor removed is less with each reapplication, but given how armor works in this game, "diminishing" certainly doesn't mean it's not still really effective and totally worth doing, especially at higher levels!
