While Adrian and the others took care of the preparations for the approaching primordial beasts, Frey managed to almost reach the summit of the mountain that she was climbing. It is not just the sudden snowstorm that impeded her on the way but also the terrain becoming unforgiving. The winds that blew on the mountain became harsher and harsher as she came near the summit.
If she did not stab her spear on the ground for stability, then she would have been blown away by the fierce winter winds. She even got some stab and cuts due to sharp blades of ice hitting her as hail became frequent as well. The hail that hit her was not normal as the shape of the ice projectiles was not even circular but looked like sharp bullets. Frey had to actively use her own mana to make her skin tougher in order to reduce the effects of the hail.
