You *could* start where you want the frag with the dremel and then you'll be more likely to snap off in that cut area. Then you don't have to cut through the whole thing. It's worked for me on montis before. Iodine or coral revive dip may or may not save it. If I were you, I'd frag at least 1/4" above/below the decay and hope for the best.
