Asha watches her companions attack the shambling pile of leaves. She reaches out and summons the shadowy hand to rake across the mount of rotting plants.
A volly of attacks strike the unsuspecting creature at it is assailed by arrows and magic alike, Hrgach appears to be more interested in starting forest fires than actual combat.
The shambling mound of rotting vegetation increases its pace and begins to increase its pace as it lurches towards the party the dear horn scraping and thudding as it does. You are unsure how as this thing has no eyes but you get the feeling it now knows where you are .
GM:
So apparently I lied and it moves at 20ft just for full disclosure, it is now 40ft away from you all and will reach you next round of this pace keeps up.
Hrgach summons a flame then hurls it at the mass which seems to smother the flame with its mass causing it to be less effective than the hobgoblin would hope. Hrgach companions prove to be even less useful as there attacks seem to bounce harmlessly off the creature as it continues to bound towards you.
GM:
The mound is now in melee high Hrgach but unable to attack this round. It also has resistance to fire attacks.
