Kelvin is up, then I'll do a summar

Kelvin steps forward, a picture of tranquility amid the strange environment. After 15', he turns and flicks a sticky glob wrapped in paper behind him. The ground under Glim turns slippery as a layer of fatty oils spread underneath.

(Grease: Need a DEX save from Glim, DC 16, or fall prone. The ground around him is Difficult Terrain.)

 As the grease spreads out under him, Glim is caught off guard, not expecting this even from Kelvin, but, having cast this spell himself many times, is able to anticipate the way the grease spreads and keeps his footing.

"What... are... you...," he seethes, before pausing, as if making a mental calculation, and turning to Fi and Klong, "I think Kelvin's charmed! Minerva and I are going to look for what did this. Fi, maybe your raven can look too if we can't spot it?"

He then steps out of the grease puddle and walks toward where Kelvin had been standing, narrowing his eyes to search for the presumed hidden threat. Jumping out of his pocket and scurrying off at a right angle from Glim, Minerva does the same.

Glim casts Web, ensnaring both of the near Shambling Mounds in spider silk.  Fionula connects with two well targeted Eldritch Blasts as the nearest plant sizzles.  Klong smashes away ferociously and leaves some pretty visible cuts and damage to the tangle of leaves and branches.

Fil, stuck on the bridge calls upon his Druidic powers to bring down a powerful Moonbeam.  Somewhat surprisingly, Kelvin casts Grease underneath Glim's feet, causing Glim to suspect something is controlling his friend. A quick scan of the area provided no clue however.

Glim: 18 -->23

Fionula: 23

Fil: 19

Klong: 19

Kelvin: 16

??? : 14

Far Plants: 12 (-0, -0) 40 feet from end of bridge roughly 170' away from main group, 100 or so from Fil)

Near Plants: 5 (-0, -63) damaged plant needs Moonbeam save next turn, both plants restrained

Fionula

"Well that's just peachy. Seriously, pratfall is the best he can come up with? Maybe we leave him this way! Swifty," she shouts, "Find!"

Swifty looks for a hidden attacker while flying back towards this side of the bridge. Perception: 14

Then Fionula casts Dispel Magic on Kelvin while backing away another 10 feet.

Range is 120', so no worries there. She is casting it at 5th level, so it dispels anything of 5th level or lower, and if it is higher, here is her spell casting ability check vs a DC of 10+the spell level of whatever she is trying to dispel: 9

Edit: It is quite possible that Swifty didn't bother actually looking. :)

Swifty flies around and comes back with a worm. You see the glaze on Kelvin's eyes disappear as you Dispel whatever was controlling him

Kelvin smilea at Glim, "Wasn't my fault there, but that was a bit funny. Just told 'stop him'."

Klong, realizing that there's something else out there, understands that it's imperative to cut down the number of attacks. He continues to hit the injured mound with his hammer, and gives inspiration to the grey skinned gnome. "Greyskin, you can do anything you want do when you put mind to it!"

"I've never been more grateful for your ability to interpret people's words in the most favorable way possible to your own purposes," Glim replies dryly to Kelvin.

Then hearing Klong he swivels his head, and with a puzzled expression, says, "Like I needed you to tell me that." Though he somehows feels (even?) more confident, nonetheless.

Fil doesn't want to get in close to these mounds, so he is going to cast Faerie Fire in the area on the nearby plants and then move back toward the beginning of the bridge. 

Once again the far Mounds will dash 40 feet in (now 80' feet in almost at middle of the 200 foot bridge). 

The damaged Mound attempts it's save vs Moonbeam: 14 for 28 damage (1/2 if save succeeds)

Gah, need to retcon the near Mounds actions as I realized the 'unseen thing' may impact it.  The rolls for Moonbeam did not change.  Should the Mounds have to make a strength check (if Glim maintains concentration) they will and will fail (rolls of 11 and 4)

There is some rustling in the trees and you hear some muttered words.  Suddenly the earth erupts (Erupting Earth 6th level) all around Glim, Fionula, and Kelvin, as if a major earth quake had occurred, sending dirt and muck flying everywhere. 

I need DC 16 dex saves from Glim, Fionula, and Kelvin (and Gargosh). On a failed save you take 41 damage, half if you succeed. I also need a concentration check from Glim

Gargosh save: 18

You know the source is in the bushes near the bridge about 60' away.  A DC 14 perception check will reveal his exact location.

Map coming soon

Fionula's dex save: 4

Ouch. I shall take my 41 hp of damage.

Are we also prone?  I see the spell description says nothing about that.

Counterspellers: For future rounds (since he will certainly be spotted by his next turn) I will let you know before casting if he is and if you know the spell what it is so you can decide to counterspell or not

Nope, but it's difficult terrain in a 20 foot cube centred on Glim

Glim DEX save: 25

Glim Concentration save: 27

Matisse would be proud

Map question: If Fi were to back up to the left, directly away from the ???, how far away from ??? could she get before she is in danger of getting swallowed by the swamp? And how much of that movement would be in difficult terrain?

Faerie Fire would kill the concentration on Moonbeam. Do you want to do something else or kill Moonbeam?
