In D&D, it can be tempting to try and do everything. You want to have all these spells, and these prestige classes, and these feats, and even these various skill ranks... yes, it can be tricky to fit everything that catches your eyes into a single build. But what if you were able to sub in what you want when you want it now and then? You might not be able to trade out class levels on the fly, but whenever you see someone using a cool feat, do you not think to yourself "I wish I could try that"?
Well if you're willing to look way back to a dubious little corner of an unofficial web article, you just might be able to try that.
Mirror move is a 2nd level bard/wizard spell that allows you to make like Taskmaster and copy any physically demonstrable feat that you see. If you're wondering why you haven't seen nor heard of this admittedly funky spell, it's because it's from a somewhat dubious source - a web article published in 2001 that was never subsequently included in a book, updated for 3.5, or otherwise mentioned again. Yes, the same source as guidance of the avatar and other suspect tidbits. Still, it was published by Wizards, so if your DM doesn't mind you can have some fun with this one.
If it wasn't obvious already, I have a deep love for open-ended feats and spells. Having a single option that can be tooled to the current situation rewards creativity and inventiveness without demanding perfect foresight or having an overabundance of niche options prepared "just in case." After all, you can rarely be certain of what you'll come across in any given day of your adventuring career, let alone while adventuring in general, so having a multi-tool can keep you from being caught with your pants down. Unlike a lot of the usual "cast this and pick what you want" sorts of spells, though, mirror move functions a little differently.
