That's great, thanks for the feedback. It's definitely something I'll be thinking on.
I went back and forth on having abilities "cross over" into other classes' arcs, and considered, for instance, making the arena fights nullify non-physical damage.
I wasn't too happy with that though, so eventually decided an easy encounter was your reward that finding an "outside set" of abilities that blew open something like the arena. That said, it's obviously a bit anti-climatic when you can just march through each fight, so I'll continue thinking on ways to mix it up.
