Patch V2.04 is out, signifying another step in Izo's development. Some changes have been made to tone down his powers, along with straightening some lore too.
 * Because of how "A Merchant's Rescue" became a story of an encounter with Izo by a merchant who does not get rescued, the story has been renamed with the suggestion given by Double Slap. Thank you to him once again.
 * Quotes have been added to give more life to his speech lines.
 * Seeing how the Northern Gale's name is close to "the Northern Winds," I took some liberties and made them the primary Iceborn inventors of True Ice weapons. This is only an experimental thought, so if anyone are displeased with this addition, just say so.
 * Many nerfs have been made to Izo's abilities, such as scaling down certain values. Some were for the sake of toning down Izo's powers in the late game, but some, such as the grounding duration, were made because they were made too strong. Some minor buffs may have been made, but overall, there's been stat nerfs.
 * The rooting effects on Field of Rime has been nerfed so that it now only affects in a smaller radius with lesser effect to those on the outer edge of it. This gives reason to have his ult.
