This tunnel is getting a little hot. I'll press on - I've got a LUCK of 11. Oh, what, surviving a hot tunnel is a test of SKILL? But I rolled a 1 at CharGen!
I didn't learn very much from this read of Deathtrap Dungeon, but every time I think about Fang and the Trial of the Champions I am reminded of the way in which I can solve the 'Ierendi problem'. You can keep much of that Gazeteer's zaniness - a key part of Classic D&D - if you add a dash of the Deathtrap Dungeon/Port Blacksand flavour to spice it up a little.
