Credit: Zerggy tempo Exploderman Tips: *Headshots build up Afterburn much, much faster than body shots. *Spells refresh the full duration of Afterburn. Use Flame Dash after igniting someone to keep them burning, and try to save Napalm for extending the burn in a pinch. *Napalm damage amp also works against buildings & objectives; Infernus takes walkers very quickly. *Use the stun from Concussive Combustion to set up a free Afterburn. *Warp Stone can be used during Flame Dash to give vertical mobility.
