"YOU DO NOT LIKE MY GARDEN?" asked the voice, but the party carried on determinedly.
A large shape moved in the darkness, and there was an odd spitting sound. Several dragon's teeth fell onto the ground, and were sucked in.
"I don't like the look of this!" said Halk, worried. "I have a thing about dragon spit! It's disgusting! Think of all the adventurers' bodies rotting in it's mouth. Eew."
"Umm, I think the other stuff that comes from its mouth should be more worrying!" said Chani, rolling her eyes.
"Like skeletons?" asked Daroou.
Chani had to choke off a sarcastic comment when the skeleton breaking from the ground almost sliced her head off. A fireball did not seem to kill it.
"They're magical!" said Chani, throwing Daroou in the way of one for being quite so smug.
"Quick, use the heroic weapons!" said Halk, grabbing the weapons from where Alex had hidden them, ready to sell later when the party forgot about them.
Which is actually a good idea, and possibly why you needed to have the party take them with you.
Toss two coins in the air. If you want to actually catch them again and look at which face came up, even better. A head is a '1' and a tail is a '0'. Add up the total. If your heroic weapons have any bonus/penalty, use it now.
