@Lyra and Kejak: Assuming the See Invisibility and Scent are always active on the items, please roll me Perception.
Forgot to add +1d8 from Inspiration. 34+=36
There is something or someone else here. You noticed a shadow moving through the door running towards the dwarf; as if someone small, in sturdy clothes, with an excellent stealth and invisible.
There is something or someone else here. You smelled it - the direction is something towards the door. You know whatever it is, knows how to hide its steps very well.
A hard "knock"-like sounds comes from the direction of the door, from outside, although it didn't exactly sounded like someone knocking at it. The dwarf turned his back to the group, looking again to the door and getting his weapon ready.
Well, gents, this is it. I'd tell ya to remember me, but I guess you will do it if ya can. As always, a pleasure fighting by yar side.
"You! Stop!" Lyra commands, towards the empty room - she barks a quick invocation and her hands glow pink for a second.
Sensing something amiss, though he does not hear or see anything, Nesipho quickly stands up from his sitting position, his rapier coming to his hand as he stands.
Initiative
Nesipho: 25
Nesipho feels something is amiss, and quickly stands up and draws his weapon. Kejak, connected to him, is even faster to act, casting Arcane Sight and entering his fighting style.
The monk feels a little delay on the onset of his spell, but finally his eyes shine and he sees himself surrounded by magic auras to every side. The dwarf might be the only one not shining at all, but there are auras around him.
He's shocked - as his companions - when the head of the dwarf flies. Kejak didn't see much of how it happened, neither Nesipho.
For Kyra, however, things are different. She sees the creature - a kobold - behind the dwarf, clearly now, as he swings his tail, equipped with some sort of weapon, across the humanoid's neck. The creature looked like either it perfectly studied the target, or had an inhuman level of precision. The kobold becomes immediately visible to the other party members.
He starts immediately laughing as Kyra's spell works. It's now prone and laughing maniacally. For her shock, however, she felt for a moment the spell could turn against herself, as if it had a chance to do so.
Kyra sees other figures - kobolds, she imagines - invading the room. There are five of them, besides the laughing one. One moves and positions himself around 10 feet behind her; the other two pairs surround Kejak and Nesipho. The kobols are probably all invisible as well, given the confusion of Kyra's companions. They're coming through the door as if the door wasn't there.
The entire thing happens so fast that, by the end of the round, the party members see themselves in the strangest of situations. The body of the dwarf stood there for some seconds in place, until it finally collapsed on the floor.
Some sort of muffled sound comes from a barrel on the far corner of the room, as if someone pushing at it.
<Guys! I see a lot of magic going on here! What's happening?>
Though he suspects there are more people in the room, Kejak is trying to receive feedback from his friends in order to act properly.
Nesipho, preparing to turn invisible himself has a change of plans at Kejak's thoughts invading his mind.
At a word, a brief burst of white light emanates outward from him.
