Lawrance is not stealthy. He will hang back in the second wave, stay about 5-700 feet away. He will then cast Arcane Eye and scout the area until the lair is found, reporting back. The undetectable eye then will enter and discover as much of the lair as possible until it expires.
Cratol is still on the ramparts of the castle looking down at the vast forest wondering where his companions are headed and if the castle could be of any use to them. Not knowing what is going on he keeps looking for any flying dragons.
Velon will stay back a ways from the lead scouts, using his silence stone only for a second or two here and there to move himself and his bulky armor and gear quickly before stopping to listen once more. He doesn’t want to keep the stone active for too long and miss a call from one of his friends nor miss hearing an enemy approach. He always keeps the lead scouts within view however, likely within 100 ft.
Taking Lawrance's lead here it would be remiss of me not to also include die roll's for stealth, and (Active)perception for Amabalis, the pseudodragon.
Will do that here, three rounds, he has natural darkvision to 60 feet, and blindsight to 10 feet, included. Likewise going from branch to branch, taking shelter in foliage.
Tazskan, using the command (Previous) to the glam leather, to change to camo leather with advantage. To stealth (Dexterity). Dai's discretion on mod here. Tazskan has no mod for Dexterity (Raw).
Has goggle's of "The night" draped around his neck, for ease in putting on later. Will not advance directly, into the waterfall area, until scouting report has concluded.
Most likely, would move in the second wave, with Lawrence after successful scouting by familiars, have reported.
Out of Character: Tazskan, now considerably lighter, with glam leather, is less noisy than previously thought. But because he is a relatively bulky, creature will still need to move more cautiously, and slowly.
I just had a decent idea, but how it could be used it depends on one thing. Daishain, since Poljen used used his ritual to speak and see through Trammet's eyes, we traveled to where we met the elven patrol, then to where we met the hybsils (Or whatever they are called), and are now moving towards the waterfall. Has Poljen gotten that ritual back? Because an eagle attacking a hawk might be great cover for us to move closer.... It might work better if Poljen controls Trammet right up until the eagle strikes…
