Gulphagor is feasting on BBQ tonight! Here is a quick guide on how to use the Infernum Augment to spam Brimstone. Required Mods: Duration Shards Duration mods like Primed Continuity Arcane Concentration Archon Intensify Step 1: Cast Brimstone Step 2: Find a rune. Step 3: Cast Uriel’s 3. (This procs arcane concentration AND damages your demons.) Step 4: Pick up the rune. (The fireball buff will now last 8 seconds because of arcane concentration.) Step 5: Fly around and rain down fire until brimstone is charged. Step 6: Land Step 7: Cast Uriel’s 2. (This procs arcane concentration AND archon intensify. Remember how we damaged our little demon buddies at the beginning of the cycle?) Step 7: Cast Brimstone. (Mine lasts about 24 seconds.) (Arcane Concentration will give an extra 60% duration. Archon Intensify will give an extra 30% strength.) Begin the loop again. If you see a big group of enemies you can also yeet the grimoire orb into it to get even more duration!
