15-20 (Good)

You expertly go through the motions, the words flowing from your memory, as you feel the magic surging through your fingers.

You hear the drow shout a word in an unfamiliar language. One of the spiders shoots something from it's abdomen, and gags you with a web of spider silk, making you unable to finish the spell.

"Looks like I'll need to watch out for this one", the drow mutters to herself, eyeing you with something between surprise and annoyance.

Without your superior magical capabilities, your comrades are quickly overwhelmed.

If only Paladin and Fighter had done their jobs right and covered for your casting, they'll get an earful when you arrive at whatever camp this barely dressed harlot will take you. To your dismay, you and the others are being stripped of your weapons and items, and down to your undergarments. You try to balk at the indignation, but a glare from the drow silences you completely. She fastens a purple ballgag around your mouth, no doubt to keep you from casting any more dangerous spells... but then why would that moron gag the others as well? With your hands bound together with spider silk, you and your group are then being led deeper into the Underdark.
