All living creatures (Creatures who are not constructs or undead) apart from the caster within the area of effect take 1d6 points of magic damage per caster level, to a maximum of 20d6.
Range is actually Medium, not Long, as the in-game description suggests.
This is a higher-level, magic-damage fireball-like spell. It fills a role, if you need it, of damaging many creatures with damage they cannot ever resist. It also never affects the caster, so can be used with impunity if the caster is the only one in range of its effects. In PvP, many players mistakenly believe that the spell uses negative energy or death magic to accomplish the effect and cast spells designed to protect them against those kinds of attacks. However, the damage is strictly magical and it is not a death spell - as evidenced by its description in the source books.
"This spell evaporates moisture from the body of each subject living creature, dealing 1d6 points of damage per caster level (maximum 20d6). This spell is especially devastating to water elementals and plant creatures, which instead take 1d8 points of damage per caster level (maximum 20d8)."
The damage is not the greatest, and it cannot be maximized due to it being level 8. It can however be empowered if one has 3 or more levels of Arcane Scholar of Candlekeep. If empowered, it does 30d6 points of damage, which is 5d6 points of damage more than Burst of Glacial Wrath and also has the benefit of being a damage type that the opponent probably cannot protect against. Hence, it is a far superior spell.
The spell is actually supposed to be especially devastating against creatures depending on water (water elementals, plants etc.), similar to the Dehydrate spell. This is however unimplemented.
