Just ran my first session last night .... 6 total PC's at first lvl
Caius - Human Ranger
Sneak - Human Rogue
Derrik - Dwarven Cleric of Clangedin Silverbeard
Tarin - Elven Warmage
Roxas - Human Silver Dragon Shaman
Corad - Human Wizard
I ran them through the Mining Camp side adventure posted here as written and they worked together well and with the exception of the sleep spell cast by Ugloop nobody dropped.
First encounter with the wolves I added a hungry wolf and they handled that encounter quite well.
THEN came the acid beetle swarm and Mad Slasher encounter. I added a swarm .... WELL by the end of the fight ... nobody was at full HP and the only people standing were Corad, Sneak, and Caius. Sneak saved the day with a couple of his molotov specials, thank god that character is a pyro.
They ended the session going back to the mining camp to lick their wounds.
