Zach felt like there weren't enough hours in the day, eyes on his face, or limbs on his body to do all that he needed and wanted to do. He had to gather information for several separate goals. He had to train and learn how to stand on spikes.
He had made some progress on that front. He could practice by making spike-formed barriers. Unfortunately, they weren't as sharp or pointy as the spikes in the swamp Locale. There was something about a defensive barrier skill not making good weapons.
They were a good beginner step, but it wasn't enough to really get those chiseled foot muscles and the balance he needed.
