Four-tick auto-attacking, abbreviated as 4taa, is an exploitation of RuneScape's tick system which is possible due to differences between two-handed and dual wield weapon attack rates. An auto-attack is cast every 4 ticks (2.4 seconds) for a dual wield weapon with "Fastest" attack rate, whereas a two-handed weapon with "Average" attack rate is 6 ticks (3.6 seconds). Four-tick auto-attacking allows the player to auto-attack with the rate of a dual wield weapon, with the increased damage of the two-handed weapon.

A player demonstrating four-tick auto-attacking

A weapon auto-attack will always be based off the rate of the weapon used for the attack prior. For example: a wand is equipped and is auto casting every 4 game ticks, then a staff gets equipped, the staff's first auto-attack will be on the 4th tick, and every auto-attack following will be every 7 ticks.

With the introduction of the Evolution of Combat, a magic spell can be placed on the action bar. Due to the ability bar not cancelling most player actions, auto-attacks and abilities can be cast on the same tick, despite the 1 tick cooldown between auto-attacks and abilities. Auto-attacks and abilities paired together can be very powerful, and four-tick auto-attacking can be up to a 5-7% increase in damage per second if done with little error.

Jagex had planned to remove 4-tick auto-attacking by changing the way auto-attacks and ticks interact with abilities, and add a Magic threshold ability that temporarily allows the usage of auto-attacks in between dual-wielded magic abilities. Ranged and Melee were also planned to receive changes that increase combat's actions-per-minute in return for higher damage-per-second.[1] However, these plans were made low priority and made an option in May's Build-A-Backlog poll[2] following the removal of continuous four-tick auto-attacking.

Usage[edit | edit source]

It is recommended to have a mouse with extra buttons, which can be remapped to equip a wand, orb, and staff.

  • Place the desired spell on an action bar, and key-bind it.
  • It's suggested to key-bind the spell with a key that is easily accessible, such as V or C.
  • Use an ability with dual wield weapons.
  • In between the global cooldown swap to a staff.
  • After the global cooldown has finished, wait 1 game tick (0.6 seconds) and press the key-bound spell and an ability at the same time.
This can be done easier by spam pressing the spell and waiting for the white flash of the ability bar as a signal to use the next ability.

Usage with concentrated blast[edit | edit source]

4-tick auto-attacking can also be used alongside the concentrated blast ability, however doing so will require more input.

  • Place the desired spell on an action bar and key-bind it as you would normally.
  • Use an ability with dual wield weapons.
  • In between the global cooldown swap to a staff.
  • After the global cooldown has finished (Indicated by the flash on your action bar,) wait 1 game tick and press the key-bound spell and switch to dual wield magic (wand and off-hand) and then press concentrated blast. This is more difficult to do as it requires more inputs in a short space of time, all of which (from the spell onwards) must be done within a 0.6 second timeframe. To know if you are doing it correctly, the 1st hit of concentrated blast should land 1st, followed by your staff's auto-attack and then your 2nd concentrated blast hit after the staff auto-attack.

This can allow for a 4-tick auto-attack alongside sonic wave/concentrated blast after every magic ability if alternated like so:

Usage with magic/melee and magic/range hybrid[edit | edit source]

Similar to 4-tick auto-attacking with concentrated blast, this can be taken further by incorporating it into melee and ranged combat when hybriding.

Just like with 4-tick auto-attacking with concentrated blast, swap to melee/ ranged weapons (and armor unless using hybrid/all equipment.) followed by an ability with the combat style you have just switched to. This will cause you to use a magic auto-attack with your staff as well as a melee/ranged ability. One key use for this is allowing you to bridge the gap between you and your target when swapping from magic to melee by 4-tick auto-attacking with barge.

Tips[edit | edit source]

  • Select auto-cast spells with dual-wield weapons equipped, to ensure that an off-hand spell is selected as well. Not having an off-hand spell selected will effectively lower ability damage by 33.3% whenever using dual-wield weapons.
  • Have auto-retaliate disabled.
  • Using full manual rather than revolution mode will prevent abilities being triggered before the auto-attack is ready. It is possible to 4taa with revolution by queuing the key-bound spell during the GCD and then pressing it again while manually clicking an ability, but this is not widely done as most who use 4taa use full manual anyway.

Continuous 4taa[edit | edit source]

Continuous four-tick auto-attacking

Continuous four-tick auto-attacking, abbreviated as c4taa, could be done the same way as normal four-tick auto-attacking, but instead of using an ability with a staff, a wand and orb get equipped and an ability is used in the same tick. This allowed a staff auto-attack to be cast every 4-ticks instead of every 7 ticks, increasing damage per second even more, but requiring a lot more actions per ability.

The key action in continuous four-tick auto-attacking was the use of an ability with dual-wield weapons, which set the auto-attack delay back to 4 ticks instead of 6. This was determined to be a bug,[3] and was fixed in the update on 21 May 2018. Continuous four-tick auto-attacking is no longer possible.

Limitations[edit | edit source]

  • It is currently only possible to four-tick auto-attack with Magic, as there is no way to auto-attack from the ability bar with Melee or Ranged.

Update History[edit | edit source]

  • patch 29 November 2021 (Update):
    • Fixed an issue that caused ranged abilities to not correctly put the players auto attack on cooldown.
  • patch 21 May 2018 (Update):
    • With this update we’ve fixed a bug related to continuous four tick auto attacking (C4TAA) if you want to read about it in more detail please click here.[3]

Trivia[edit | edit source]

Though c4taa was patched on 21 May 2018, it was still possible to c4taa with a staff auto-attack and a Ranged ability. This interaction has been patched with an update on 29 November 2021.
