Skul The Hero Slayer - Playthrough Part 4

I've obtained a couple of pretty cool new skulls. One was the Great Warlock, who attacks with multiple projectiles and his skills are extremely powerful spells like a screen clearing meteor and some magical spikes. To gain the full potential of those spells you need to charge them for quite awhile, which leaves you vulnerable and that's not great against fast enemies and bosses. Next was the Rockstar, which looked cool, but it was hard to control. To realise its full potential you have to do solos (attack continuously) and you rarely get a chance to do that. I managed to upgrade the Ghost Rider skull, which looked even cooler and left a flaming trace wherever it walked. Next we have the Prisoner from Dead Cells. He has a pretty unique ability where when you collect 5 cells from defeated enemies you gain a temporary buff. Haven't played Dead Cells, so I don't know how accurate that is to the game. In the shop, where you can exchange one of your current skulls for a new one I discovered the Ninja. It's extremely fast, has great range with its special movies and can even teleport upwards when you are in a pinch. It can also dash 3 times, but the dash-distance is somewhat shorter. Using it, I managed to defeat one of the Leiana sisters, but unfortunately this enrages the other and she uses the Dark Quartz and her move set is completely altered including teleports, quick dashes and screen-covering slashes. At this point she quickly murdered me.
