## Component summary

This component brings all Mephits in the game closer to their PnP counterparts. Legitimately missing abilities are restored and spuriously granted benefits are removed. For this purpose, the AD&D Planescape Monstrous Compendium Appendix was used as reference. The Mephits' AI has been improved as well, and it now allows them to act in accordance to the behavior described in the source books. In effect, these changes may slightly increase the difficulty of dealing with Mephit opponents.

## Mephits by type

Mephits are nasty messengers created by powerful planar creatures to perform evil missions. All known types of mephit draw their substance from the Elemental, Paraelemental, and Quasielemental Planes. Their faces have exaggerated features, including hooked noses, pointed ears, wide eyes, and protruding chins. Their skin continually oozes the stuff of their home plane. Mephits regenerate in contact with the stuff of their substance, or an appropriate environment (i.e. fire mephits in open flame, ice mephits in cold, and so on). They cannot heal by other means.

## Mephit breath weapons, spell-like abilities and special traits

As per PnP rules, Mephits cannot be interrupted while using their spell-like abilities, all of which have a casting time of 1. In all other aspects, spell-like abilities function exactly like the spells which they mimic. On the other hand, the mephits' breath weapons are treated as supernatural abilities and are therefore not subject to magic resistance and bypass spell protections such as a Minor Globe of Invulnerability.

Breathe Grit
To use its breath weapon, an Air Mephit inhales sand, dirt, or other particles in the vicinity and then blows the grit at high velocity towards a single target within 10 feet dealing 1d6 points of missile damage.
Boiling Rain Storm
Once per day a steam mephit can create a rainstorm of boiling water over a 20'x20' area. This storm inflicts 2d6 points of fire damage to all victims in the area of effect.
Chilling Touch
Whenever an Ice Mephit strikes a target in melee with its claws, the victim suffers a 1 point THAC0 penalty per each hit. These effects are cumulative and last for three turns.
Color Spray
Upon the casting of this spell, a vivid, fan-shaped spray of clashing colors spring forth in front of the caster. All creatures in the area of effect are entitled a saving throw vs. spell to avoid the effects, if they are above the 6th level or above the level of the caster. Blind or unseeing creatures are not affected. Creatures that are not allowed a saving throw, or that fail their saving throw, and whose level is below or equal to the level of the caster are struck unconscious for 4 rounds; those whose level is 1 or 2 greater than the level of the caster are struck blind for 2 rounds; those that are 3 or more levels above the level of the caster are disoriented and unable to think or act coherently for 1 round.
Extraplanar Traits
Extraplanar creatures are immune to Death Spell and are unaffected by all Cure and Cause Wound spells.
Flame Fan
A Fire Mephit may employ its breath weapon as a fan of flame which covers a 120 degree arc in front of the mephit to a distance of five feet. Any creature in the arc suffers 4 points of fire damage (no save).
Flame Jet
A Fire Mephit may employ its breath weapon as a flame jet 15' long and 1' wide which automatically hits one chosen target dealing 1d8+ 1 points of fire damage. A successful save vs. breath reduces the damage by half. Other creatures who cross the path of the flame jet will also take damage as long as they stand in the flame.
Flash of Flame
When a smoke mephit dies, it disappears in a flash of flame. This flash causes 1 point of fire damage to all creatures within 10 feet.
Gaseous Form
Once per day a Mist Mephit can assume gaseous form for 6 rounds. In this state, the creature becomes transparent and insubstantial. Fire and electrical damage can harm it normally. All other attacks are ineffective. A successful dispel magic can revert the creature to its natural state. While in gaseous form, a Mist Mephit regenerates 3 hit points per round.
Glass Dust
Dust Mephits can breathe a 15' radius cloud of irritating glassy dust three times per day. Humanoids who fail to save vs. breath weapon suffer a 4 point Armor Class penalty and a 2 point THAC0 penalty for three rounds. Mephits, elementals, undead and other non-humanoid creatures with thick or insensitive skins are immune to this effect.
Grow
Once per day, an Earth Mephit can grow to a height of 10' for one turn. The mephit's fists do 2d6 damage at this size.
Gust of Wind
A strong blast of air originates from the caster and moves in the direction he is facing. It disperses any gas-based spells in the vicinity.
Heat Aura
A Fire Mephit is constantly surrounded by an aura of heat. Anyone attempting to strike a Fire Mephit in melee suffers 1 point of fire damage.
Heat Emission
Magma Mephits emanate waves of extreme heat. Anyone standing within 30 feet of the Magma Mephit takes 1 point of fire damage each round.
Hover
This ability is available to a creature that can fly with either perfect or near perfect maneuverability. The creature can halt its movement while flying, allowing it to hover. This effectively prevents ground-based spells such as Earthquake, Entangle, Grease and Web from affecting the creature. Furthermore, creatures with this ability can cross lava and acid pools without taking damage by hovering above them.
Ice Shard
Ice Mephits can breathe a volley of ice shards every other melee round, up to three times per day. This volley automatically hits a single victim within 15 feet dealing 1d6 points of cold damage (save vs. breath weapon for half).
Lightning Bolt
A Lightning Mephit's breath weapon is similar to the Lightning Bolt spell, except that it always does 3d6 damage (no save) and only affects a single target. Since Lightning Mephits are fully healed when hit by electrical damage, they may occasionally use their breath weapons on each other when severely wounded.
Lightning Discharge
A Lightning Mephit's torso and limbs are thin, jagged bolts of lightning. Anyone attempting to strike a Fire Mephit in melee suffers 1d3 points of electrical damage (save vs. paralysis to avoid).
Magma Ball
Once for every three rounds, a Magma Mephit can use its breath weapon hitting a single target within 10 feet with a blob of lava and dealing 1d6 points of fire damage. Magma Mephits can use their breath weapon up to eight times per day.
Mist Ball
Mist Mephits can breathe a sickly-green ball of mist every other round, up to three times an hour. The mist ball automatically envelops one victim within 10 feet who must save vs. poison or take 1d4+1 points of poison damage and become blinded for 2 rounds.
Salt Crystals
The Salt Mephit's breath weapon is a shower of salt crystals. It can be used once per round against a single enemy within 15 feet dealing 1d4 points of missile damage. Furthermore, the target must save vs. petrification or become stunned for 1 round.
Sooty Ball
A Smoke Mephit's breath weapon consists of a sooty ball usable every other melee round, an unlimited number of times per day. This sooty ball automatically strikes one creature of the mephit's choice within 20 feet dealing 1d4 points of poison damage and blinding the target for 1 round (no save).
Stone Spit
Three times per day, an Earth Mephit can spit a rock at a single target within 15 feet dealing 1d6 points of missile damage.
Taunt
Once per day, a Salt Mephit may attempt to taunt a single humanoid creature. The target must save vs. spell or become berserk for one round, rushing forth to attack the mephit in melee. If the victim cannot reach the mephit during a single round, it attacks the nearest creature instead.
Wall of Fog
By using this spell, the caster creates a billowing wall of misty vapors in any area within the spell range. The wall of fog obscures all sight, normal and infravision, beyond 2 feet. The misty vapors persist for 1 turn. A Gust of Wind or a Zone of Sweet Air spell will disperse the vapors.
Water Jet
Steam mephits can breathe a scalding jet of water every other round. The jet automatically hits one target within 20 feet and deals 1d3 points of fire damage. There is also a 50% chance that the target will be stunned for 1 round (no save).

## Mephit Gating

Once per hour, a mephit may attempt to gate in other mephits, albeit with a 25% chance of success. The number and type of the gated mephits varies and is summarized at the bottom of the main statistical block for each mephit type. ;Only mephits which were not themselves gated may open gates. Note: Mephit gating can be disabled at any time with the following console command: CLUAConsole:SetGlobal("RR#MNOGT","GLOBAL",1) It can also be re-enabled with the following command: CLUAConsole:SetGlobal("RR#MNOGT","GLOBAL",0)

## More sensible mephit encounters

In the original game, the grouping of different mephit types in the gameworld was fairly random. For example, the original designers routinely paired up Ice and Fire Mephits together thereby ensuring that they would wipe each other out using their breath weapons. Per PnP rules, mephits of opposing elements don't really like to associate and avoid working together if possible. In an attempt to rectify this, a small number of changes were made to the placement of mephits within certain areas. Here's the full list:

- AR0315 (Rayic Gethras' home, ground floor) - Ice Mephits replaced with Steam Mephits
- AR0601 (Irenicus' dungeon, air room) - Fire Mephits replaced with Smoke Mephits, one of the Mist Mephits is replaced with a Steam Mephit
- AR1512 (Spellhold maze) - Ice and Smoke Mephits replaced with Mineral Mephits
- Watcher's Keep (several areas) - Air Mephits replaced with Lightning Mephits, Ice Mephits replaced with Salt Mephits, Smoke Mephits replaced with Steam Mephits

## Compatibility

- The PnP Mephits component uses Detectable Spells and is therefore incompatible with the Improved Anvil mod
- In order to achieve optimal compatibility with Sword Coast Stratagems I & II, Spell Revisions, Tactics and Big Picture, you should install aTweaks after those mods.

## Known Issues

- None
