Basic Spell Stats:

Power:
A spell's power determines how much damage the spell does, or much it heals. See damage calculation for exactly how a spell's power affects the damage done.

Hit Rate:
Hit Rate determines whether a spell hits or not. The higher the Hit Rate, the higher the chance to hit. See the chance to hit calculation for detailed info on how Hit Rate works.

Reflectable:
If a spell that is reflectable is cast against a target with reflect status, then the spell is reflected back against the casting party.

Absorbed by Runic:
If the Runic ability has been used by a character, and a spell is cast that can be absorbed by Runic, then the spell fails, and the MP needed to cast the spell is absorbed by the character that used Runic.

Physical Damage:
Most spells and skills do magical damage, however spells that do physical damage use the standard physical damage calculation algorithms. For damage purposes, the spell's power is considered to be the Battle Power of the attack. See the damage calculation algorithms for exact information on how physical and magical damage differ. If a spell does physical damage, it is considered in all ways a physical attack, and is affected by things like Clear, and Safe.

Ignores Defense
Spells that ignore defense treat the target as though it has 0 Magic Defense. They also ignore other parts of damage calculation (Step 5, Steps 6b to6f and Step 7 of the damage calculation algorithm are skipped).

Ignores MBlock
Spells that ignore MBlock treat the target as though it had 0 MBlock. and (almost) always hit. See Step 3 of the chance to hit algorithms.

Spell special abilities and effects:

Summons Golem to protect the party
This ability is used by the Golem Esper, and summons a Golem hand to protect the party from physical attacks. The Golem hand will block physical damage for all party members. Any physical attack that hits a character is blocked by Golem. The amount of damage it can block is equal to the HP of the caster when it was cast. Once it has blocked that much damage it will no longer block attacks for the rest of combat.

Morphs target into item
This ability is used by the Ragnarok Esper, and can turn a monster into an item. Each monster has 4 items that it can be morphed into with the Metamorphability. Each item has a 1 in 4 chance of being the item that the monster is morphed into. Check the Monsters page to see which items each monster can be morphed into, as well as the odds of successfully morphing the monster.

Heals entire party except caster
This is ability is used by Mantra, and heals every character except the caster. It heals an amount of HP equal to the caster's (current HP / (number of targets - 1). Sabin is considered to be a target for purposes of determining HP healed.

Caster is removed from battle, fully heals party
This is ability is used by Spiraler, and heals the HP of all characters except the caster. It also removes the caster from combat, killing them, and leaving them with 0 HP, and 0 MP.
Also removes the following statuses: Dark, Zombie, Poison, Imp, Petrify,Condemned, Mute, Berserk, Muddle, Seizure, Sleep, Slow, Stop, and Freeze.

Party runs from battle
This ability is used by Warp, and causes the party to run from a battle. When cast, the party automatically runs, unless a monster is present with the Can't Run ability. If used outside of combat it exits the dungeon you're in.

Damages all targets with level divisible by last digit of gold
This ability is used by L? Pearl, and only hits targets whose level is evenly divisible by the last digit of the amount of GP the party has. Ignores the automatic hit caused by Vanish at step 1 in the Hit Determination algorithms. Removes Vanish from the target whether it hits or not.

Halves the target's level
This ability is used by Dischord, and cuts the target's current level in half. This effect is only temporary and the level is restored at the end of combat. Note that no HP or stats gained from the level is lost, it only reduces your level for purposes of things like determining damage.

Exchanges all status effects between target and caster
This ability is used by Rippler, and exchanges status effects. Any status effects that the target has are given to the caster, and any status effects that the caster has are given to the target. Due to a bug, this exchange all status effects, including things like Life 3, Rage, and Morph. It will also exchange Shadow's Dog Block ability.

Deals damage based on target's level
This ability is used by Flare Star, and ignores all normal steps in damage calculation (except step 9 - elemental resistance) and instead damage is calculated as follows: Damage = 80 * (level of a random character that is hit) / Number of characters hit.

Target will block physical attacks aimed at caster
This ability is used by Love Token, and when used gives the target and "invisible Love Token status". While under the effect of Love Token, a character will step in and take damage from any physical attacks that hit the monster that used Love Token. This "status" can only be removed by killer the character affected, or the monster who used the ability.

Captures the target and slowly drains their HP
This ability is used by Seize, which is used by the Tentacles in Figaro Castle basement. When used the character hit is grabbed by the Tentacle and can't move or act. The character slowly takes damage (see seizure status). After a short period of time, Discard is used to release the character.

Targets a character
This ability is used by Targetting, and has no real effect when used. However, when Doom uses it, that means that the next time Doom uses it's special attack, Demon Rage, it will always target the character effected by Targetting.

Nullifies one random element
This ability is used by Forcefield, and when used will nullify at element at random. If an element has been nullified then any attack of the elemental type does 0 damage for the rest of the combat. When used, it will always nullify an element that hasn't already been nullified, so after 8 uses all elements will be nullified.

Drains HP and MP from the target
This ability is used by Empowerer, and drains HP and MP from the target hit to the user. The amount of HP drained uses the standard damage calculation algorithms to determine damage. For purposes of determining the amount of MP drained, the Spell Power is considered to be 1/4 of its normal value.

Gives target a 20 count, after that becomes a Zombie
This ability is used by Overcast, and when used gives the target a countdown the same as Condemned status . Any time a character affected by Overcast dies (including when the counter runs out), they become a zombie. This affect wears off at the end of combat.

Possesses target until they die
This ability is used by Zinger, which WrexSoul uses. When used WrexSoul disappears and possesses a random character. When the character that is possessed dies , then WrexSoul reappears.

Next time caster is hit with a physical attack, counters with Retort
This ability is used by Retort Swdtech, and when used gives the user an "invisible Retort status" which lasts until the character's next action or until the character is hit with a physical attack. If the character is hit with a physical attack, then Retort is used. Due to a bug, if the character has died and been brought back this combat, then any physical attack is countered with Retort, whether it hits the user of Retort or not.

Slowly drains target's HP
This ability is used by Phantasm, and when used gives the target an "invisible Phantasm status", which slowly drains the HP of the target. The damage from HP loss is the same as from Seizure status. However, it is not Seizure and effects that remove Seizure will not remove the effect. Only dying or wining the fight will remove this effect.

Discards a seized character
This ability is used by Discard, and when used ends the effect of Seize.

Damages all targets with level divisible by X
Abilities with this effect only hit targets whose level is evenly divisible by a certain number (3, 4, or 5). It Ignores the automatic hit caused by Vanish at step 1 in the Hit Determination algorithms. Removes Vanish from the target whether it hits or not.

Deals extra damage if target's level equals caster's level
This ability is used by Stone, and when used adds 6 to the damage multiplier (see step 7 of damage calculation algorithms) if the caster and target hit are the same level.

Randomly misses targets
This ability is used by N. Cross. Spells with this ability determine which characters are hit normally, but then has an additional step as follows:
After determining which characters are hit, it randomly makes N. Cross not hit 0, 1, 2, 3, or all 4 characters. Which character(s) it sets as not hit is completely random.

Misses if target is immune to instant death attacks
Spells with this ability will automatically miss if the target is immune to instant death attacks (see the Monsters page to see which monsters are immune to instant death attacks). This is checked at Step 2 of the hit determination algorithms, which is after Vanish checks, so if the monster is Vanished it stills gets hit even if immune to instant death attacks.

Does not split damage when hitting multiple targets
Spells with this ability skip step 3 of the damage calculation algorithms, and do full damage when hitting more than one target.

High Stamina increases chance of missing
Spells with this ability have an increased chance of missing based on the target's Stamina. See Step 5 of the chance to hit algorithms for exact details.

Misses if target is immune to all statuses of spells
Spells with this ability will automatically miss if the target is immune to all status effects set or removed by the spell. This miss is checked at Step 2 of the hit determination algorithms.
