I'd say the terrain/corridors aren't even or straight enough to run (though she can still hustle with a double move). Luckily this also means that the duergar won't be able to charge (though they could still get a charge off easier than Bremorel could get a 120 straight line to run).<br/><br/>This is the dramatic moment when the heroine flees and trips only to fall to the ground and look back over her shoulder to see the approaching villain...! Or maybe not.<br/><br/>Maybe I can change your mind about running away by mentioning that these guys can use<em>enlarge person</em>on themselves? ;)
