Table 2 presents average hazard hardness, dents, and damage by level. At 1st level, the average hazard will kill a low hp character class, but at high levels, is less of a threat. In addition, hazard hardness progresses so quickly that by the time a character can get Adamantine weapons, they aren't any good. To modify that, I would suggest that Hazard damage be scaled to a percentage of a (6+6) character's hit points, assuming Con increases each 5 levels. The following table is built to half a (6+6) character's hit points at each level, attempting to keep half of the average in bonus, and half in dice. It also lists hardness/dents to maintain hit points with lower hardnesses to let those expensive weapons do something for a little while.
