A guide to Crimson Guardian killing

Well, you could use it to ensure that they aren't close enough to start their attack in the first place.

Well, DB isn't fool-proof. Not by any means. Not to mention that I'd really like to my mob of 4 or less Crimson Guardians with an attack other than DB, in between DB's. DB -> Pupput behind -> RUN RUN RUN THROUGH THE GUARDIAN sounds like a sound strategy, though.

I think I'll try it once I have a few more charms or whatnot.
