Kingdom Rush Alliance - Navira boss fight (Impossible difficulty)

I recorded myself playing through the entire stage but for some reason errors keep occurring while I upload, so I have to stick with the boss fight…
Kingdom Rush Alliance’s recent Undying Fury update has a new boss: Navira, who is actually Arivan possessed. He’s definitely much tougher than the main campaign bosses, no kidding about that!
Navira can disable up to 3 towers at a time and transform into a tornado, making himself unblockable temporarily. In addition, he has a massive amount of HP and deals very high damage. My strategy was to weaken him with the Arborean Emissaries and have the Arcane Wizards use the powerful “Disintegrate” ability to crush him, but they went for the weaker enemies instead. That didn’t work out the way I wanted it to, but I still beat Navira! Barely though however, that was such a close victory. Maybe Royal Arches or would’ve worked out better? Aw well. A win’s a win!
