The Arachyr/Firebats build doesn't use Hex angry chicken correctly, it only turns into a chicken then runs around till it ends/dies and doesn't ever force the explosion skill with monsters around 
Would be good if the chicken was implemented correctly for speed runs, I tried to look at it myself but I have no clue what to change.
