Path of Exile 2 - Fire Summoner Witch vs. Act 3 Final Boss

This is my take on a fire summoner in PoE 2. It is a very comfy 1button playstyle (Firestorm) for clearing zones, while adding a 2nd button (Gas Arrow) to quickly nuke rare monsters and adding a 3rd button (Flammability) for even more damage against very tanky rare monsters or bosses. You can ofc. only stick to Firestorm to keep it a 1 button build but adding 1-2 more buttons adds a lot of extra damage.
