Blue Bear Fury, similar to the Barbarian's Berserk, is an intrinsic attribute enhancement. Its flaw coincides with that of the Barbarian's Berserk, rendering one unable to cast spells. That said, when this ability is being used, it typically means one is already in close combat, where there is little chance to cast spells. Furthermore, there's a possibility of falling into the previously encountered state where magical abilities are sealed, which eliminates concern in this regard.
Unlike Berserk, this ability can be applied not only to oneself, but also to others, albeit exclusively to Blue Bear Worshippers. This is a feature of totem spells; not only does Blue Bear Fury possess this feature, but so does the Blue Bear Totem Pillar. Clearly, they are designed for those Barbarians and Berserkers of the Beast Worship Sect, to further enhance their physical strength, making them invincible in this aspect.
