Tass collects and shoulders the four flasks of oil offered up by his fellows, while Flin chips away stubbornly with flint and steel to put a spark into the small bundle of tinder to light the lantern.
After what seems like an age he finally gets it smoldering, when Raislin leans over and points his Zippo finger at it and--with a guttural word--causes it to ignite hungrily. Humph. And thusly, the lantern is finally lit.
At last little Tass, burdened with four oil flasks and the bulky lantern, staggers off toward the supply yard, while the rest of the party wait...
Ever so less sneakily than usual, encumbered as he is, Tass makes his way quietly as he can around the site and to the supply yard.
So far, so good. He pauses for a breather; all these flasks of oil sloshing around are a bother.
Dabbing the sweat off his forehead, Tass mentally selects two good-sized timber piles as his targets, and makes his way through the supply yard to the nearer as sneakily as he can. Getting there, he plonks the shuttered lantern down then unslings and unspots two of the four flasks of oil. That done, he up-ends them--one in each hand-- into the heart of the wood pile.
Glug, glug, glug... goes the oil as it chugs out of its flasks.
Just as the flasks are emptied and Tass is about the dump them into the pile, a voice suddenly rings out:
"Oi!"
Tass instinctively looks up at one of the workers on the scaffolding peering right down at him. A bunch of other rooftop workers stop to look around too. "Whaddaya think YOUR doin??!"
(Back at the staging point, it's more muted, but the party hear something is afoot...).
There is the implication of action IC. I will assume it is so....
...
Does Tass elude the perimeter guard to reach the supply yard unseen? 1d6=6, yes he does.
Does Tass douse a timber-pile at either end of the supply yard with two flasks of oil without mishap? 1d6=2. Erk.
Is Tass surprised? 1d6=4, so no. He saw/sensed it coming in time, so he can react simultaneously with the NPCs.
What about the rest of the party? 1d6=3, so yes. They'll have to wait until after Tass' immediate reaction before doing anything.
So, what now Master Burglar? You have mere moments to react...
