So as i said, i'm currently dming the tyranny of dragons campaing and my players are at chapter 3. They explored the dungeon backwards as they went trough the small tunnel in area 2 of the dragon hatchery, took care of the guards and continued in the sanctuary, where mondath joined forces with cyanwrath. They managed to defeat both of them and literraly took the chest in the room, activating the acid trap. They then ran to area 10 and encountered the hidden kobolds throwing bombs. The roper managed to grapple both healers (one is uncouncious) and talked a bit with the rest of the party, offering to trade fresh meat for the friends.

The ungrappled players went out of the room to get help from a militia (the flaming fist from Baldur's gate) they brought with them and to collect some meat.

The concious grappled player told me that his character will consider that his friends abandoned him, so he might turn evil. In game, he told the grappler that his friends might go get the militia to kill the monster and he offered to lure the militia into the grappler's den if he let him live.

I should also mention that they went to Baldur's gate instead of doing chapter 2 and they brought and they brought a part of the flaming fist with them.

The party consist of a wizard, a fighter, a monk, a druid (the unconcious grappled) and a cleric (the conscious).

What should i do as a dm to keep things fun for everyone.
