  • The choice between this mod and Mod TT 20px.png Point Strike depends greatly on the weapon.
    • If the fire rate penalty is offset by using fire rate increasing mods such as Mod TT 20px.png Speed Trigger, the resulting gain in fire rate (or net loss in fire rate, if Mod TT 20px.png Shred is used) may be enough to justify the opportunity cost of two mod slots because of the increased critical chance bonus, particularly so if no fire rate increasing mod would have been used in the absence of this mod.
    • The fire rate penalty is most severe on weapons with a charge trigger such as CorpusSniperRifle.png Lanka (both lengthening charge time and interval between shots), and bows (on which the negative property of the mod is doubled).
    • The fire rate penalty is fairly severe on automatic weapons, leading to less of a DPS increase than offered by Mod TT 20px.png Point Strike, even on those weapons which the most benefit from the critical chance bonus: U10InfPrimary.png Synapse, ChainLightningGunEdit.png Amprex.
    • The fire rate penalty is least severe on non-charge trigger weapons with a magazine size of 1, where it is practically unnoticeable (e.g. GrnGrenadeLauncher.png Tonkor), and is experienced as being relatively mild on weapons which normally require adjusting aim between shots (e.g. DEVectis.png Vectis, Vulkar.png Vulkar, DexSybaris.png Dex Sybaris).
      • On such weapons, players may try using this mod alongside other critical chance mods to maximize critical chance, while practically ignoring the fire rate penalty. By doing this, users can increase the reliability of critical hits and/or gain a chance to score critical hits of a higher order.
  • The true utility of this mod is observed indirectly: it increases ammo efficiency and uptime (interval between reloading), especially on weapons with a high rate of fire, during the use of which ammo is regularly wasted in the time between the target dying and the release of the trigger.
    • Most notably, users may discover that equipping this mod on GrineerAssaultRifle.png Grakata is reasonably beneficial, as the reduction in fire rate lessens the effects of recoil, leading to greater hit probability, and together with increased uptime and critical chance, to a possible increase in sustained damage potential. However, as it's possible to reduce recoil directly, while preserving fire rate, this still to suboptimal results in most respects.
  • The fire rate penalty supports Mod TT 20px.png Internal Bleeding's low fire rate bonus.
    • Assuming no other fire rate penalty, weapons with a fire rate of 3.12 or lower will activate Mod TT 20px.png Internal Bleeding with this mod equipped.


Patch History[]

Update 30.5 (2021-07-06)

  • Critical Delay - Critical Chance from 187% to 200% -36% fire rate to -20% fire rate

Update 29.10 (2021-03-19)

  • Critical Delay has been given a buff to their Critical Chance from +48% to +187%.
    • These new Mods (Mod TT 20px.png Internal Bleeding and Mod TT 20px.png Hemorrhage) have a greater effect if Fire Rate is below 2.5, and this buff brings a synergy between these Mods. As a result, Critical Delay can no longer be equipped with Point Strike.

Hotfix 11.3.3 (2013-12-13)

  • Fixed in-game stats for weapons that fire continuously (Flux, Synapse etc). Made fire-rate mods actually increase damage output and ammo consumption rate for these weapons (not only is this intuitively what you would expect it's important to maintain the balance for corrupted mods like Critical Delay).

Hotfix 10.7.1 (2013-11-08)

  • Fixed corrupted mods not accounting for Conclave Values.

Update 10.3 (2013-10-09)

  • Introduced.
