Burning Pitch

Burning Pitch is a Technology researched at the Fortress which does damage over time to any unit it hits. Burning pitch damage goes through all armor, making it particularly effective against units which have been upgraded in the Armory. 
The arrows cut trees so might be a risky idea if you are using a forest as natural defense in your base.
In the metagame, Burning Pitch is one of the strongest features of the Norse civilization. The community believe that it is over-powered and in need of a patch. As a result, it is currently not available in the Champion Mode tech tree in Project Celeste, the only technology to be outright removed from the mode rather than rebalanced.
