Forge, you find throwing the axe and manning (dwarfing?) the rope to be a challenge...
The axe disrupts the tendrils, but it is not enough to overcome the shifters own lack of spryness. Ghen is hit and pulled into the necrotic rain (15 dmg). His strong instincts coming into play, he then pushes back off the wall. (end round, those who need a save can make one). He's gone down about 15 feet.
