The fire was a mental strain, but it WAS keeping them from simply ignoring the wall, causing the smarter ones to let the more frenzied ones go first, which was stalling the charge a fraction. Then he heard the sound of the oil canisters going, and let go of the wall, and touched the spreading oil, easily found by its affinity with his personal element, fire. He brushed his power against each spreading stain of oil, and grinned as the oil ignited right in the middle of the army, and only continued to spread. "AGAIN! AGAIN AND AGAIN, UNTIL OUR LINE HOLDS!"<br/><br/>He could ignite more puddles, but at this point, he was exhausted, and had little left but his reserves for the boss. And if that was more difficult than he expected, he might not even have enough for that. He did a quick calculation as he took the head off a landing troll, the flaming blade easily killing it as the most important piece went flying off into the storm.<em>Enough for close combat enhancements, at least an hour, all the remaining oil jars... and just barely enough left over to ignite the kegs if I need them. I think I cut this one rather fine. Time to start working on magical stamina and efficiency, me thinks.</em>
