all leveling the ground does is HELP her to get at you when she lands for melee. Uneven terrain borks her up so you can avoid that phase if you want to shoot. With better armor, if you want to melee, that is fine and the flat terrain helps you both.

I built a good size trench around the spawn pedestal so that I could shoot her from below her and if I needed more food or stamina got low I could just run around the circle and be safe for a few seconds. It took a while, like all day in game, and the closest I came to death was due to a few wolves that ganked me, but I got her. Because it will take so long, solo at least, best to have a near by base with a portal so you can get there early with full rest and food buffs, as if you didn't know that, right?
I wonder how a few ballistas would help...
