So you want to beat Titan HM

This is how I avoid plumes 99% (no one can guarantee 100%) of the time in p5. Right after first Mountain Buster, he will start stomping, this is followed by plumes. I start moving just before they show up to eliminate any potential lag spike (can dodge 90% of the time anyway). He will use bombs soon after, after they are dodged, Mountain Buster will soon follow. After MB, it takes about 3 seconds for the next set of plumes, start moving just before they show up. After he uses rock, MB is used shortly after, followed by stomps, followed by plumes. Rinse and repeat.

You don't need to remember his whole pattern for p5, only a few things that tell what's coming up.
