I'm better with crystal powers than Crystal Guardian and he's just mad about it. Sometimes he acts all mean and exploits my one weakness of ordinary walls. However, the cool part happens at 1:46. Most importantly, I finally used Heavy Blow.
My friend Gnagghi from HK Discord suggested killing a boss using crystal dash with Brooding Mawlek. I learned it is possible, with pixel perfect positioning, to damage critters with crystal dash and not be hurt (ordinarily, if the measly 10 damage from crystal dash doesn't kill something when you fly into them you'll be hurt). However, doing this 105 times on radiant difficulty was not happening. It also took a very long time to kill it with crystal dash on attuned which would make for a boring video.
So instead I switched it to a crystal dash killing blow with only dashing otherwise for damage on a boss who has a crystal theme right near where you get crystal heart in the first place. It's like all the pieces of the puzzle fit together.
