While Marcus and his team, and James and his were stuck dealing with a multitude of challenges, the only group composed completely of beast companions was having a different type of trial.
Currently Inten, Blitz, and Eirwen were stuck in a room with a large bookshelf in one corner and having to learn and practice new skills.
For them there was no time limit and they all simply needed to learn knew staple skills that most people would have had by their levels but as beasts they had never picked up.
These included staples like mana body, mana barrier, speed burst, and other such skills.
Normally beasts just typically had heightened physical abilities and were not intelligent enough to pick up skills like these that required training.
