Immunobreak, Negative status ranks drafting



Immunobreak

Overview

The Immunobreak system is a mechanic that was introduced in the July 24, 2012 (JST) Version Update which allows the player to lower a monster's magic evasion to certain negative status effects through the successive casting of Enfeebling Magic. When a monster resists an Enfeebling Magic spell, there is a chance an Immunobreak may occur. This is indicated by a message that appears in the chat log. The following is an example:

Player casts Sleep on the Huge Hornet.
→The Huge Hornet resists the spell.
→Immunobreak!

Mechanics

An Immunobreak occurs when certain Enfeebling Magic spells are resisted which results in the monster's resistance rank to the negative status effect that triggered it to lower by one rank. This reduction results in the lowering of the monster's magic evasion to subsequent casts of the same negative status effect. Any Immunobreaks triggered afterwards by the same Enfeebling Magic will stack in a cumulative fashion and further lower the monster's negative status resistance rank. This rank will stay at its modified level until the corresponding negative status effect successfully lands.

This is beneficial not only to the Enfeebling Magic used to lower the monster's negative status resistance rank, but also to any source capable of applying the same effect such as Blue Magic or certain avatar Blood Pacts.

  • Example: A player casts Silence on a monster. The spell is resisted, but an Immunobreak occurs. Not only will the monster's magic evasion be reduced for subsequent casts of Silence, but spells such as Silent Storm can take advantage of this reduction as well.

A monster's resistance rank is reset to its original value when a corresponding negative status effect is successfully inflicted upon it. The more times a monster's resistance rank is reset, the more difficult it will progressively become to trigger subsequent Immunobreaks.

  • Note that it is the monster's resistance to Immunobreak itself that increases and not its resistance to the negative status effect.

There is a limit to the number of times a monster's resistance rank can be modified and then reset as a cycle. The number of Immunobreak cycles possible depends on the monster's starting negative status resistance rank. Once this limit is reached, it will no longer be possible to trigger an Immunobreak on the monster for that particular negative status effect.

  • One Immunobreak cycle consists of any number of Immunobreaks triggered, the successful landing of the status effect and subsequent reset of the monster's resistance rank to its original value.
  • Any corresponding negative status effects that land at the monster's starting resistance rank without any Immunobreaks will not count towards the maximum number of Immunobreak cycles allowed.

Immunobreaks can only be triggered when the starting negative status resistance rank of a monster is rank 30% or higher.

  • If a monster's starting rank is C (40%) or lower it will not be possible to elicit an Immunobreak.

During an Immunobreak cycle, negative status resistance ranks may be reduced at most to a rank of 50%.

  • If a monster is completely immune to a negative status effect, it will not be possible to trigger an Immunobreak and the chat log will display a "completely resists" message. The following is an example:
Player casts Sleep on the Huge Hornet.
→The Huge Hornet completely resists the spell.
    • Starting with the implementation of the Immunobreak mechanic in 2012, many monsters released prior had their resistances changed in the following months to reduce the amount of foes that have complete immunities. That being said, there are still many monsters that have been introduced since then that possess immunities to certain status effects throughout various content.

The chance for an Immunobreak to occur varies from monster to monster, and can even vary between the different Immunobreakable negative status effects of a single monster. It is possible to increase the chances of one occurring in the following ways:

  • Enfeebling Magic skill: The higher your Enfeebling Magic skill is, the higher your chances of triggering an Immunobreak are.
  • Resisted Spells: The more times a spell is resisted, the higher the probability of an triggering an Immunobreak.
  • Saboteur: this job ability increases the chance of an Immunobreak occurring for Enfeebling Magic spells cast while under its effect.
  • Immunobreak Chance Merit Point category: Each merit placed into this Group 2 category will increase your Immunobreak rate by 3% up to a total of 15%.
  • Immunobreak Chance equipment augment: The Red Mage relic boots starting with the Duelist's Boots +2 up to the fully upgraded Vitiation Boots +3 are augmented with an additional 1% chance to trigger an Immunobreak per 1 point invested in the Red Mage Group 2 "Immunobreak Chance" merit point category, up to a maximum increase of 5%.

Currently, there is only one piece of armor in the game with the "Immunobreak +1" stat: Chironic Hose

  • This stat allows the player to reduce a monster's resistance rank by two ranks per Immunobreak instead of the usual one while equipped.

Negative Status Resistance Ranks & Immunobreak

Monsters use separate negative status resistance ranks for hit rate calculations and resist states.

  • The following status effects rely on these ranks: Amnesia, Bind, Blindness, Charm, Dark based sleep (such as Sleepga), Elegy, Gravity, Light based sleep (such as Repose), Paralysis, Petrification, Poison, Silence, Slow, Stun and Terror.
  • These negative status resistance ranks operate separately from elemental resistance ranks and have their own characteristics.
    • Example: When the spell Paralyze is cast on a monster, this spell does not refer to its Ice elemental resistance rank for hit rate calculations despite Paralyze being an Ice-based spell. There is a separate Paralysis resistance rank that is used instead (this only applies to player to monster interactions).
      • While it is common for the negative status ranks of normal monsters to match the element of the spell being cast, there are many instances where this is not the case. This is especially true for countless Notorious Monsters.
  • Monster negative status ranks use the same magic evasion table as elemental ranks for hit rate calculations.
    • For example, a monster with a matching Ice elemental rank and paralysis rank of 60% will require the same amount of magic accuracy to reach the 95% hit rate cap for both ranks.
  • Negative status resistance ranks cannot be lowered by the job ability Rayke.
  • Performing a Skillchain will not lower a monster's negative status rank, however, performing a Magic Burst with spells that can Immunobreak will still grant a Magic Accuracy bonus.
  • Spells that lower elemental resistance such as Threnody do not affect the magic accuracy of spells that rely on negative status ranks.

Within the chart below is a comparison of how elemental resistance ranks compare to negative status ranks. Immunobreak's interaction with negative status ranks is shown as well.

  • At rank 5%, both elemental and negative status ranks are guaranteed a full resist.
    • Any Enfeebling Magic that lands in conjunction with the job ability Stymie at this rank can bypass this resist state, but will only last for half duration.
  • At rank 10%, this is where elemental and negative status ranks begin to diverge in behavior. Negative status ranks, like elemental resistance ranks, are capped at a 5% hit rate. However, negative status ranks do not have a guaranteed 1/2 resist at ranks 50% and higher.
    • This means that it is still possible to land a full duration spell at ranks 10% and below.
