James was surprised that his attack could only do that much, because even when he attacked the hippo earlier, he could penetrate its armor when his fire attribute was already at a disadvantage in the first place.
However, he assumed that it was probably due to its skill [Mutated Amor Vines] that made its defense hard to penetrate.
The bear roared loudly as its hands, reduced to ashes, and he immediately used its skill [regenerations] as its hands began regenerating rapidly.
James then decided to deplete the bear's mana, because if it still won't move from there, James was confident that he could kill it using his [Fire vortex] multiple times.
As James cast his [Fire vortex] skill again, the previous magic circle vanished as it was replaced instantly by another.
When the bear saw that James was about to cast the same skill as before, it immediately accelerated the regeneration of its arms.
