Lina Arcana is the Fiery Soul of the Slayer in Dota 2, and this cosplayer has taken the fiery part of that description to heart. Táy Máy Tò Mò appears to have fashioned a budget costume with Coca-Cola labels and the like, but then he sets his hands and his head on fire. The flames burn and he looks to be completely unharmed.
After the break you’ll find a video of the Lina Arcana cosplay along with another video that explains the secret behind the trick. Apparently, the flame effect was produced using a concoction of dishwasher soap and Axe body spray. This is definitely in the “don’t try this at home” zone.
