Investigation check 'nat 1'

Clear the dungeon down below
Facing challenges we don't know
Scrolls and potions there were a few
Swords, shield and armour brand new

Studied and searched all the lore
To find the way to the next floor
We even got a high ranked thief
So no trap will give us grief

We left no prep undone
Why is it that we must run
As fast as we can down the hall
To escape this unseen fireball
