I felt like there were too many knights to sneak past. Though to be fair some of them were rather predictable. I’m sorry if I sounded rude. It did make me a bit cranky though.
Regarding the boss, I liked how you gave him a Mega Aggron. Luckily I had Lucario and Excadrill.
Never mind, I figured it out myself. It took a bit of outside the box thinking, but it worked. I used a Fire Stone on my Cubone and now she's fiery. And spooky. I figured a female Marowak would be appropriate for this evolution.
