In my party I've got
Human cleric
human Rogue
human paladin
human paladin-holy gun
I've already had to fug the dice several time to keep the cleric alive. Right after the paladin fell the last 20 ft of a pit on top of the rouge because of having a -2 to clime do to armor and being in his Medium load. The cleric followed in scale mail in a Medium load with a 10 Strength so he had a -7 clime. The funny thing is this is my player that made a vole to always put points into clime after the party in a old campane almost got killed by a dragon after only half the party could make the clime check to get into his lair. Then the Rogue died when they got to the last culpable rooms when he rolled a 4 on his Disable Device and the party had a bad habit of standing 30-50 ft behind him.
