Railsplitter

Railsplitter is an ax obtained by Magnus Burnsides from the Fantasy Gashapon in Episode 9. The ax offers +1 to attack and damage rolls, as well as the ability to fell any tree once per day. In Episode 18, Magnus uses Railsplitter to cleave through Trent the Treant "like a hot knife through butter." In Episode 25, Griffin clarifies that the object must be a tree, and not a log or pole, as Magnus tries to chop through the beam connecting a giant boar to a chariot.
