Arena Ferox is new to me since I only had the WiiU version of Smash 4. It’s actually based on a location in Fire Emblem: Awakening on 3DS. It’s where Chrom fights Lucina (disguised as Marth) for the first time.
It doesn’t stay a flat stage for long.
As the mini-platforms will constantly change every now and then.
Which makes it a little difficult to predict. But I do like the stage, but it’s far from my favorite one.
