So normally armor comes from equipment! Armor subtracts from damage taken, so if you have 1 armor, you take 1 less damage from each hit. If you have 3 (like from Radja's giant boots and bracers) you take 3 less.<br/><br/>The Immolator/Branded doesn't have armor but DOES have this:<br/><br/>Fuel for the Pyre<br/>When you take damage while unarmoured,​ the flames within you<br/>come to your aid. Take 1 fuel. At any time, you may spend 1 fuel to:<br/>●Heal 1d4 HP<br/>●Take +1 forward to conjure your Firebrand<br/>●Take +1d4 forward to your next damage roll<br/>Your fuel is reset if you receive healing from any other source than<br/>your fuel.<br/><br/>So when you take damage, you build up Fuel! Fuel can be spent to heal yourself, improve chances on your core attack, or do more damage!
