Magic Evasion Magic Evasion , also called M . Evade , MBlock % , and Magic def % , is a recurring statistic in the " Final Fantasy " series . It is similar to its counterpart stat Evasion , but instead of working against physical attacks , works against magical attacks , and at a much lesser rate in terms of avoiding damage . Appearances . " Final Fantasy IV " . Magic Evasion is an equipment statistic . In the pre - Nintendo DS versions there are two statistics which determine whether a spell will be a hit or a miss ; the spell hit rate , and the target ' s Magic Evasion . Each spell has its own base hit rate . Some spells have 100 % hit rate , such as curative spells , but some , especially the status effect inflicting spells , have lower hit rates . Spells cast via weapons / items ignore the spell ' s hit rate . There are ways to affect a spell ' s base hit rate . A bonus to hit rate is given to based on the stat the spell is powered by : If the caster is afflicted with Blind , the spell ' s base hit rate is halved . The spell ' s hit rate is boosted by 25 % if the caster is in " Slot 1 " . For the characters , it is the middle slot . For monsters , it is the front most spot , but can change as they are killed . Bosses by default are in the front most spot , so always get the boost . Another factor that affects whether a spell will hit or not is the Magic Evasion . The characters have a base Magic Evasion value , which is : In the Nintendo DS version , characters can no longer evade spells that deal damage , but is the rate the characters can evade being inflicted by a status . " Final Fantasy IV - Interlude - " . Magic Evasion returns in the sequel to " Final Fantasy IV " , and works the same way as it did in that game . Magic Evasion is calculated the same way as has its predecessors , meaning that magic evasion is determined by the armor the character has equipped . " Final Fantasy V " . Some spells always hit , and curative and buffing spells always hit when targeted at party members . Offensive spells ' accuracy is decided by the caster ' s Spell Hit % and the target ' s Magic Evasion % . When the player equips the Aegis Shield they have a random chance of evading a spell , which is separate from their actual Magic Evasion statistic . Hats and robes give Magic Evasion . Most shields don ' t have any Magic Evasion and the only helm with Magic Evasion is the Royal Crown . If the spell is multi - targeted the Spell Hit % is halved . Spells that are naturally multi - target do not suffer the penalty . If the target has Shell , the Spell Hit % is also halved , and if the target is a Toad its Evade % is reduced to 0 . The game generates two random numbers between 0 and 99 . In other words , even if the target does not evade the attack , the attacker can still miss . " Final Fantasy VI " . Magic Evasion was called MBlock % in the older translations . Due to a bug in the game coding , Magic Evasion affects both evasion to magical attacks and evasion to physical attacks , and the regular Evasion stat does nothing . Magic Evasion is an equipment statistic , but most equipment don ' t offer any Magic Evasion . The best equipment pieces for Magic Evasion are the Force Shield ( 50 % ) and the Force Armor ( 30 % ) . Most spells use the following formula to decide if a spell hits or not : The Evasion can be a value between 1 - 255 ; if , from the above formula , it comes to less or more , it is set to 1 or 255 , respectively . The spell hits if it meets the following formula : formula _ 6 However , Break , Doom , Gravity , Graviga and Banish use can be blocked by the target ' s high Stamina ; if formula _ 7 the attack misses .

Some spells are also unblockable , such as Quake , although the party can use Float to immunize themselves . If the target is afflicted with Sleep , Petrify , Freeze or Stop attacks always hit . Targets can be hit 100 % of the time with physical attacks when hit from the back , but this doesn ' t work for magical attacks . Spells auto - cast from weapons can ' t be evaded , such as how Ragnarok randomly casts Flare . " Final Fantasy VII " . A spell will hit its target 100 % of the time under any of the following conditions : If none of the above conditions apply , the party member ' s chance of evading a magical attack is simply the Magic def % listed on his or her armor . Even if the character does not evade the spell , the caster still has a chance to miss . " Final Fantasy IX " . Spells ' accuracy is decided by the spell itself , and the target ' s Magic Evasion . The spells that have a chance of missing are mainly all status spells , as well as Comet and Meteor , but Comet and Meteor ' s hit chance is random and unaffected by the target ' s Magic Evasion . The spells ' accuracy values are as follows : For Bio : " Final Fantasy XI " . Magic Evasion is a stat in " Final Fantasy XI " that can mainly be found on equipment pieces . However , the stat is " hidden " as there is no way for a player to display his current total magic evasion . This stat is used to determine two things - whether a spell effect lands on a target , and to what extent magic is resisted . Like evasion , magic evasion is used to determine whether a spell effect ( such as Sleep ) lands on a target , the outcome of which is either a hit or miss . If the effect lands , there is a possibility that its duration may be partially resisted due to magic evasion . For example , the Sleep spell lasts for 60 seconds if not resisted , but may instead last for 30 seconds due to a partial resist . However , for magical damage , which cannot outright miss , magic evasion is instead used to determine how much the magic is resisted . This is shown by fractional damage reduction . When magic damage is resisted , it is typically a half resist ( 1 / 2 damage taken ) , quarter resist ( 1 / 4 damage taken ) a 1 / 8th resist or the lowest which is a 1 / 16th resist . The opposing stat to magic evasion in " Final Fantasy XI " is Magic Accuracy . " Final Fantasy XII " . Magic Evasion is a shield statistic , however , only three shields in the game have any Magic Evasion . The evasion chance can be boosted further by purchasing Shield Block augments on the License Board ( each augment adds + 5 % to shield evasion ) and by equipping the Gauntlets accessory . The strongest bosses in the game , however , such as Zodiark and Yiazmat , ignore shield evasion . One can ' t evade attacks while fleeing . Magick Evasion does not block status effect spells , such as Poison . " Final Fantasy XIV " .

Resists may reduce damage by 25 , 50 or 75 % . With high enough MEVA in comparison to the enemy ' magic accuracy , it ' s possible to always resist spells by at least 25 % . It has been noted that notorious monsters usually have high magic accuracy and require very high MEVA for resists to happen . Certain abilities cannot be resisted at all . " Final Fantasy Tactics " . Magic Evasion is not affected by direction of any unit . Magic evasion is determined by this equation : This applies to most magic attacks , whether they are status - inducing or damage - causing . Also , a unit will not try to evade attacks that are curative or that add helpful status . However , these can still miss based on a target ' s Zodiac Compatibility , and on the Faith scores of the caster and target . " Final Fantasy Legend III " . The higher the number for M . Evade , the easier it is for the character to dodge against magic attacks .
