"Now that you mention it, I hear giggling too."

Triäsa moves towards the area the sound is coming from. (Perception: 20)

Not taking any chances, Daventry quickly moves to keep pace with Triasa. She gives the other woman a nod, her free hand holding her belt buckle, close to her blade. 

Ludolf looks around but doesn't see anything that would be the source of the giggling and is unable to come up with an idea as to what might be making the noise. As he ponders this thought everyone sees a pink cloud of smoke with highlights of silver sparkles hit him straight in the face. Ludolf please make a wisdom saving throw (DC 11).

The rest of you hear a crashing come from behind you in the direction of the door. As you turn to look you see a large potted tree and planter was knocked over and now blocks the door back to the hallway.

Despite how much any of you squint or strain none of you can see anything that might be causing these disturbances. 

Ludolf Wis save:24 Ludolf takes a deep breath and chuckles. "Whatever this smoke is my mind is impervious to such simple tricks. I believe our giggler is invisible and is playing some trick on us." Ludolf says and grabs some soil and throws it in the direction the smoke came from, hoping to at least briefly expose this trickster. Throw soil (dex?) : 20

(OOC: Don´t know why I got the red flag, but the save was nat 20 and I think the throw was 9+2=11)

"What in the nine hells..."

Daventry looks at Ludolf. Does the wizened old man look like he took a blast of glitter right to the face?

The dust sprays Ludolf in the face and for a moment he has the oddest sensation, is this happiness? No surely not and he quickly rejects the silly emotion and willfully fights it off. As he throws the dirt in the air he feels a strong wind almost like the beating of wings as the dirt blows forcefully back into his face. If you were to look at Ludolf at this moment you would see a man whose face is now covered in mixture of pink sparkling glitter and dark brown, well fertilized soil. A mocking giggle erupts from high above, something seems very pleased.

As Klin jumps back startled from the vase he too his surprised by as a glitter bomb, this time blue, hits him in the face. Klin please make a Wisdom Save DC11.

(I will leave this out of initiative to keep things moving as it is not really combat but I will try to give you all chance to act before I do anything. I'll post any results of your actions as I see them though)

@Klin As the blue dust hits your face and you breath in the blue glitter you feel a sense of joy, no joy is not a strong enough word. You feel pure unadulterated euphoria. You have never imagined such happiness was even possible. You couldn't imagine ever harming anything with this feeling

(you can do anything you want as long as it is non-violent and fits your current euphoric mood. I will ask for further wis saves to break free of the effect but for now RP as you see fit; enjoy :) )

Daventry laughs at the beglittered Ludolf. "It's a good look for you, old timer! Some shine to the crags, y'know? You'd light up a room like the best of a Balduran brothel!"

Glancing around, she looks for signs of the creature. "Alright, ya wee sprite. You've had your fun, now come join us all for a laugh."

Perception: 22 (dunno if the +2 bonus applies to trying to spot these creatures, not added into that roll)

Seeing the room break out in multi-colored chaos, Pardot stands still in the middle and opens up his senses to the room in an attempt to figure out what is causing the wind that he feels ((perception 17; temp passive 18))

Triäsa gets a slight grin on her face as she sees the state that Ludolf is in.  And she seems a bit amused at Klin's antics.  She fruitlessly looks about, focusing up in the air above Ludolf where the mocking laughter came from.  Realizing though this is getting nowhere she pauses before unslinging her lute from her back.  "You seem to enjoy a bit of fun, whoever you are.  Perhaps you could show yourself in return for a little music?" 

She plays a few chords, hinting at the beginning of a light song.  She then repeats it again. "But you have to show yourself to get a song." 

Ludolf, steaming hot with anger now, uses his magic to swiftly clean himself up again (prestidigitation). "Yes, come out and play, it will be so much more fun for you if we can see eachother." He says as he regains his composure, trying to make the giggling creature to show itself. Persuasion:22 using Triäsa´s words as a help action if that´s ok :-)

(Yes. thst's fine to use my action as a HELP.)

Above you far towards the ceiling in both the north and the south you hear loud, satisfied laughter followed by a playful voices that only Pardot and Triäsa understand, "Oh these new visitors are tremendous fun!" Speaks a voice in sylvian from the north. A reply is heard from the south again in a chipper, amused voice, "Yes especially the old grumpy one. I wonder what he is saying? I bet he is thanking us for all of our funny pranks!"

Pardot, you think the wind was caused by the rapid beating of wings given how localized it was and how forceful it was for a brief moment.

Klin make and other wisdom save DC13

Triasa make a performance check

Daventry again you see nothing even though you feel like you can spot exactly where the sounds are coming from

"So, two small invisible winged mischieveous creatures. I think I have an idea of what we are dealing with." Ludolf says to no one in particular. He then turns to speaking draconic.  "Come out and play, it will be so much more fun for you if we can see eachother." New persuasion if needed: 19 rolled with advantage if someone gives help action, otherwise go with first roll.

While waiting for a reply he turns back to common. "See if you can find any books, otherwise we should perhaps just leave the arboretum while we can. And try to restrain Klin, he is acting a bit stranger than ususal." Ludolf says to the others, while scanning the room for books. Investigation: 17

(OOC: Hm, missed the help roll on the persuasion so here it is just in case:22)

Daventry shouts up at the creatures, attempting to focus their attention on her. "Oy, ya little scamps! Ya like surprises? How about THIS?!"

As she speaks, she summons forth the arcane energy... Causing the mage hand to appear precisely behind one of the creatures she's pinpointed and playfully ruffle it's hair. 

Triäsa continues to strum some chords on her lute. She now changes to speaking Sylvan. "You still haven't come out for is to see."

(Performance: 18)
