Shake N' Bake (8) - Fire (/ Air), Light Armor
Occult (5) - Hidden Secrets Whisper, Spirit-Detecting Mirror Technique, Spirit-Grounding Shout, Spirit-Chaining Strike,
Terrestrial Circle Sorcery (Control Spell: Flight of the Brilliant Raptor)
Dodge (3) - Threshold Warding Stance, Flickering Candle Meditation, Hopping Firecracker Evasion
Merit - (Pact with an Ifrit Lord) The Burning Name
Uses: Your Occult charms help your team deal with spirits. The Burning Name lets you make attacks with (Intelligence + Occult), which is fun. Use Hopping Firecracker Evasion to stay out of range of melee enemies. When you have built up your withering, dump a Flight of the Brilliant Raptor on them. Consider taking the Merit Suzerain of Endless Flame.
Progression: At Essence 3 you want to pick up Dragon-Sorcerer Puissance to gain 3 sorcerous motes when you shape sorcery for Flight of the Brilliant Raptor. You can always grab additional Fire Charms like Ember-Amid-Smoke Misdirection and Unassailable Body of Fire.
Air (2) - Five Winds Rainment, Light-as-Clouds Method. If you want a bit more Defensive investment here, you can use Light-as-Clouds Method to keep your distance even more. Five Winds Raiment provides a bit more protection when shaping spells Definitely take the Unburnt Majesty merit if you aren't Fire aspected since you can expect it to spread.
I think we're nearing the end of the builds here.
