Hari blows into her horn, but no sound comes from it. Instead, sound erupts from a point in the midst of the zombies.

(Casting shatter in the middle of the horde, affecting as many as you deem fit, Virst)

Those affected, must make a DC 13 Con ST for half of 13 thunder damage.

Sylvester will continue to help the group of mushroom men, using his halfling nimbleness to move between their legs.

 Nasaar Con Save, DC 14, on fail take 11 poison damage

(Nasaar, please do save or I'll roll for you.)

Con save: 23

Does Nasaar take poison damage if he actually has not been hurt by the tentacles?  It only hit his ward, even at 19 damage...  Just want to make sure before I deduct the actual 10 points of damage he will take out of the 30 damage from that attack.

(Yes, while it is poison damage, the power originated from necromancy.)

Axon bot -

Attack: 20 Damage: 13

Zombie Saves - (Shatter would get most of them, only sparing about 2)

The two groups fight back against the zombie horde. The frontline consisting of mushroom warriors, Sylvester, Axon, Hari, and the newly joined Rusty as he drops he handbow and joins the melee. They cut and slash at the undead horde, routing 3 more of their numbers. While the backline still focuses on the creature above, this time the archers getting their mark as five of them land upon the creature as it attacks Nasaar and Kastor. But the tides suddenly turn as Hari sounds her horn.

After a moment, there seems to be nothing, then a shrilling sound comes from the horde. The zombies start to convulse and twitch to it. Then one of them implodes, then another and another. A total of 7 of them implode from the sound, leaving the rest of them just in not much better shape. Their passage collapses a bit, giving the emerging zombies a harder time to come out from there.

Zombies' Turn

 Although half of their mob was gone, the dead still mindlessly attack. A few go for the mushrooms once more while the rest try to swarm the wildfire spirit. The tentacles stop their attack as the creature is silent for a moment. Then they reappear once more, above the horde. But instead of attacking, it places more zombies into the horde.
