Rita rarely had such an uninterrupted block of time to study magic potions. Nivalis, finding these quiet days boring, transformed into a small spider to accompany Rita for a few days before returning to her pet space to sleep and play games. They had tested it out—time in the pet space was the same as outside the tower. What felt like an extremely long period for Rita was just the time it took Nivalis to play a game.
During this time, Rita had planned to run the Soul Catcher game once a month, but she discovered there was a limit: no more than three skills could exist at the same time. After unlocking Backlash from a previous run, she already had the skills A Lie and A Prank filled up, meaning she couldn't add anything new.
Fortunately, she could still use the Moon Cut ability.
