Attack: 25 Damage: 11

The zombies are being closed in on as their numbers are low. The mushrooms switch from defensive to offensive, pushing towards the zombies passage. They rout two more of the zombies as the press on to the rest of the mob. Rusty and Axon keeps up the pressure as they keep attacking with Shepard. Hari and Sylvester cut up a zombie, ending it. Sylvester's bolt does land on the creature, one of its flowers opening up at the sudden pierce. Kastor keeps pressure as he sends three rays towards it, only two landing. 

Zombies Turn-

 The creature comes down from the ceiling, crawling down from the wall over the zombies' passage. It crawls back in as it grabs the zombies that tries to go out. It stuffs them inside itself and retreats deeper into the passage. The zombies throw themselves once more at the two groups. With another swarm upon the spirit and only one getting a hit on Axon.

Nasaar sends a lance of cold at the retreating creature from the ceiling.

Hari makes a frustrated noise and does her best to reduce the horde in front of them.

Attack: 21 Damage: 9

With the tentacle creature retreating down the cave Sylvester returns his focus to the zombies.

With the Wildfire Spirit down to 1hp, both it and Kastor continue their assault on the tentacled creature (if still in sight?  otherwise, attacking the zombies).

Attack: 16 Damage: 7

As the creature retreats, the mushrooms shift their focus. The archers stay back and fire at the remaining zombies as their frontline goes to the entrance of the passage. The large mushrooms put their hands onto the cave's wall and start to close up the passage with a plant like fiber. The party is still engaged with the zombies as the few still fight. Hari cuts down into one's shoulder and deeper, practically cleaving it. The backline of the party still manages to hit their magic on the creature but it is hard to tell if the creature is dead or not as they close the passage.

 (Don't know if that kills the Wildfire)

The zombies flail at the party and the mushrooms once more, the party only taking a few light hits.

((Yeah, the Wildfire Spirit had AC13 and 1hp left, so it dissipates and fades away))

Kastor casts Shillelagh and charges into the Zombies, shouting to the mushrooms as he does so, "Don't leave! We would appreciate your help." (In common, so no idea if they understand)

Attack: 21 Damage: 7

nasaar turns to the nearest undead and hits it with his warhammer.

Attack: 24 Damage: 10

Irritated at being hit by a zombie, Rusty moves in on an engaged zed to put it down for good.

Critical Hit Damage 3 

Hari blows her horn, and sound erupts from it, blasting into the crowd of zombies.

Casting thunderwave at 2nd level, the zombies in range must make DC 13 Con STs for half of 12 damage. On fail, they're also pushed away.

 (Mushrooms)

 (The mushrooms aren't heading into the passage, they're sealing it.)

(Zombie saves)

Hari sounds her horn once more, getting the rest of the zombies in its spell. While most remain in the same spot, two of them were blown away. Then the remaining zombies were cut down by the party and the archers. A mix of beating, cutting, and piercing as the last four zombies fall. The mushrooms finish sealing up the passage with their fibers and start to pile rocks against it as well. The mushrooms stow their weapons but do look curiously at the party. The lack of mouths is a bit unsettling as the archers just stare.

Encounter Over.
