Radiance help (spoilers)

[Violet-111]

I've been working on beating the Radiance on and off for a little while and I'm not getting any farther, I always die at the second phase.

A few of the charm builds I've tried:
Quick Focus, Shape of Unn, Dreamshield, Carefree Melody
Quick Focus, Shape of Unn, UB Strength, Shaman Stone
Quick Focus, Shape of Unn, UB Strength, UB Heart, Grubsong

I have all charms, notches, masks, soul vessels, and nail arts.

I can find times to heal but she either deals too much damage at once or I don't have enough soul. I'm not getting rid of Quick Focus and Shape of Unn since I wouldn't last a second without healing, but that leaves only 6 notches for damage and defense. Do I just need to git gud?

I tried to take a video of me dying to the Radiance and ended up beating her. so that didn't go as expected. Maybe this thread gave me luck

Nice job, i personally prefer to use an all spell build against radiance, shaman stone, spell twister, soul catcher, and soul eater

Quick Focus is good, but I probably wouldn't have bothered with Shape of Unn, especially since you were low on soul anyway. On that note, when you're low on soul against a boss, Quickl Slash becomes better than Unbreakable Strength; you can often do similar damage with it, but get soul more quickly.

try quick focus and deep focus, it slows your heal to normal speed, but you heal two mask of damage in the time it would take to heal one

I actually prefer using Lifeblood Heart and Joni's Blessing with the Shaman Stone and Longnail/Soul Catcher. Trying to find spots to heal fighting the Radiance only lead to me taking more damage, so it was more beneficial to me to focus on dodging and attacking without having to worry about healing.
