Storm of Vengeance

Storm of Vengeance is a High-level class ability available to Cleric, Druid, and Shaman classes as a selectable ability option, but it may only be taken once.
The ability is selectable from the priest's level 7 spellbook.
== Gameplay ==
The caster designates a point on the area map using the targeting cursor and clicks/selects the desired center of the storm.
When the spell casting is finished a projectile speeds to the designated point and rapidly expands into a 15-feet radius Storm of Vengeance zone, which is a fixed area of effect lasting three rounds in duration - the storm overlays a unique 3D graphic effect on the area of effect, a reddish-pink cumulous cloud formation with crackling lightning strikes directed downwards.
The storm only affects enemy creatures that are in the storm's radius - it won't affect neutral or friendly/controlled/allies/party members. 
The storm applies several harmful effects:
* When the storm first manifests on the area map, a one-time instant slay effect is applied to any enemy creature with less than or equal to 8 hit dice/experience levels, killing them with a Finger of Death animation.
*The storm lasts 3 rounds, and at the beginning of each round it inflicts 1D6 Acid damage, 1D6 Electricity damage and 1D6 Fire damage (save vs spell for half) to all enemies caught in it.
*Additionally, at the outset of the storm each enemy creature is allowed a save vs. death to avoid getting a Poison status effect applied - if the save is failed, then the victim suffers 4 Poison damage per second, for 18-seconds (total of 72 damage unless dispelled/cured). If the creature succeeds with their saving throw, then the poison effect isn't applied - the following round the creature is exposed to the effect again, and another save is allowed to resist it, if failed the poison effect is applied, and so forth.
If an unfortunate exposed creature fails more than one saving throw, the poison effects will "stack", resulting in significant poison damage - note that each instance of poisoning has a 3 round duration, so even when the storm's duration expires, the poisoning effect can continue beyond the storm's life.
All of the storm's effects can be potentially blocked by magic resistance.
A creature under the Poison effect can be cured of it, or any applicable Dispel Magic effect might remove it.
== Notes ==
* The description mentions 270 ft. range, yet 50 ft. is the range according to game files.
* The spell has no assigned school of magic, and so Spell Immunity is not effective and a dual classed Evoker/Cleric get no benefit.
* Golems, undead and creatures with at least 100% resistance to Poison damage are exempted from all poison effects and survive even when level 8 or below.
== Trivia ==
The Advanced Dungeons and Dragons 2nd Edition ruleset has no Storm of Vengeance priest spell - other D&D Editions may add it as a 9th level spell.
The BG video game version is a creation/adaptation by the game developers.
