Save vs Death Ray or Poison

This Save is broad and may be interpreted as "General Hazard" either environmental or from a creature or enemy.

"The megaweapon charges its crystals with thaumic flux before discharging a heat beam at you!" Is the type of death ray we're talking about, a magic death ray wand would fall under magic wands, the spell disintegrate would fall under spells. These are for big room fixtures, contraptions or other traps along with choking gas, radiation and the like.

In addition to actual machines of death and destruction, you'll often roll this save while avoiding pit traps, spikes and other room hazards.
