Atlas made quite a contribution in fighting against the snowman. Cutting off that trunk is one big move that is good enough to reduce the danger the snowman possess to us. To ensure that the snowman does not reattach that troublesome trunk back to its body, I launched a fireball at it and burned it to ashes. With Lucia's flames that I am using, the fireball is more than enough to burn the trunk to ashes in split seconds just like how a paper got caught in a fire.
There is still a possibility the snowman can find another way to restore the arm but in the meantime, it seems the monster is not doing anything that would do that, allowing us to continue the battle.
Due to the recent attack, the snowman wanted to switch target which is Atlas but as always, the snowman seems to have no chance of breaking off from Guts as he punched the snowman again, taking off the regenerated part of its head again.
