Knowing what direction to travel in was a benefit, but also not knowing how safe the route would be put the entire party on edge. They had been working on improving Genesis for a while now without major battles, however, their habits had not died off.
Everyone was still alert and prepared to handle whatever came at them.
There was a lot of preparation for this trip, some of which allowed them to better use their strongest elemental affinity skills in the singular elemental plane. Alice for one was able to bring out more light mana from light mana crystals and mana gems stored with dense light mana.
This removed worries that Alice wouldn't be able to maintain her buffs or songs. It was the same for when they left the fire elemental plane and Remey would need fire mana. It applied to the others as well but matching the manas they might need.
