Walker felt that he needed to do more, while the water elemental arrow formed the ice he used his multi boost skill to improve the rate of attack and damage. He had been holding off for the right moment to optimize the time they had while boosted.
The water elemental mana was being pulled in faster and faster, Walker used his grand elemental manipulation and frost whips to push in even more. The mana was more than the wind arrow had just done and was already causing a significant amount of ice to form on the minimized slime.
With the additional boost of Walker's skill and the added water elemental mana the minimized slime struggles to shake free of the ice. It was constantly losing layers of its minimized slime body. The tentacles it tried to form to bring in anything it could use as food were also frozen and fell to the forest floor in shards.
