[MapleStory Reboot] Shadower Hard Darknell Solo

Nexon's implementation of a Bullet Hell, as a boss.
I cannot even begin to state how much of a difference it makes when you can solo this boss in 20 minutes or less, compared to something like a 25-30 minute solo. I noticed that it made such a big difference to my performance, both mentally and in actuality, when I got stronger and could clear this boss faster.
For some of my mini bursts, I tested out deactivating last resort as soon as I was no longer in range of the boss and could no longer safely attack the boss. I think this helped me prevent some deaths, as I would've otherwise gotten 1-2 shotted by projectiles and Darknell's attacks.
