Evading an enemy can be nearly as good as defeating it, so against enemies that have a high combat stat but low health, this can be a way to get a low-difficulty test to deal with them. Also doesn't have the drawback of dealing damage to your teammate if you miss an attack while they are engaged, or damage to yourself if you miss an attack against an enemy with Retaliate. And getting a clue to boot is a nice bonus!

Also potentially handy against Aloof enemies, as you don't have to engage them first. Make the Whippoorwills sing a happy tune for once!

Note that this does not have a "non-elite" clause, so if you're able to crank your high enough or otherwise automatically succeed (e.g. Scrape By), you can use this to make anything, even a Great Old One, dance to your tune. Or rather, sing you a tune, I suppose :)
