I Don't Think Either of These Guys Know What They're Doing

Taking the GM's hint (although not in the way he may have expected)...

With Castille approaching, hands out in surrender, Kaspar begins to wonder if his comrade has either lost his mind or simply given up. The half-orc shakes his head in disgust and frustration, but forms a plan. It seems that both the teammates are trying to buy time for the other. But perhaps, Kaspar ponders, he can rely on his speed to maneuver out of danger.

Kaspar continues to empty his pockets, but as there isn't much within, he swings his pack off next. He is worried that the kobold won't buy any bluff and so proceeds as quickly as possible.

"Here you go. Take my pack as well. I'll even give you the couple of platinum pieces I have inside." An obvious lie, but Kaspar uses the opportunity to thrust his arm into the pack. He feels for a small roundish object and then pulls it out. Thunderstone in hand, Kaspar immediately hurls it at the kobold's feet. With any remaining time, he then dives for cover -- hands over his ears.

I'm standing right next to the thing. Do you still want a roll? If so, I'll leave the dice in your hands.

As to the wisdom of this new plan, it may cause his own ears to ring, but if it buys any time for Castille to work his magic, then Kaspar will call it damage well spent.
