They Grow Up Too Fast is a hard combat achievement requiring the player to kill the Abyssal Sire before any spawns mature into a scion.

This is considered one of the more difficult of the hard combat achievements.

Spawns can appear during each phase of the fight, have 15 hitpoints and mature after 12 seconds. These will appear throughout the fight.

In phase 1, spawns will appear if the Sire is within attack range (~10 spaces), though it tends to frequently launch miasma pools. This should not be an issue as players should be using shadow spells to disorient it.

In phase 2, spawns will appear rather infrequently, but will have a much greater chance of being launched if the player is out of melee distance. As such, stay within melee distance to minimise the chances of spawns appearing.

In phase 3, part 1, four spawns will appear immediately once the Sire roots itself to the ground and becomes attackable again. These spawns must be killed immediately, and can be stacked by moving a few tiles back. After these spawns are killed, the player can take a short breather, as no further spawns will appear until the next part begins. A slow but rather guaranteed method is to let the Sire increase its hitpoints regeneration and spam Bandos godsword special attacks to drain its Defence completely to 0.

Once the Sire reaches 140 or lower health, it will begin the second part of the phase, summoning a large cluster of spawns directly underneath it while more appear from both it and the surrounding area. These spawns will need to be ignored, as they appear rapidly until the cap of 15 is hit. The spawns are also linked to the phase's miasma pools; if the minion cap is not reached, then the Sire will continually launch miasma pools until the cap is met. Enough damage must be dealt in 12 seconds; using the tips below can also be helpful in obtaining the achievement.

Advanced tips:

• Without access to chinchompas or barrage spells it is still possible to kill all 4 spawns in phase 3 via ranged or magic, with some luck. With access, try to target the central spawn of the pack. Some ways to kill the spawns are using Venator bow or Dinh's bulwarks special attack.
• After the 4 spawns are killed, no more will appear until after the teleport, giving an opportunity to prepare.
• The teleport will occur when the Sire goes down to 139 hitpoints, and the following explosion can hit the player for up to 96 damage.
• If using Vengeance, overheal with an anglerfish and cast Vengeance right before reducing the Sire below 139 hitpoints. If the explosion reduces you to low health beware of dying from the spawns and miasma pools.
• After the explosion run back to the Sire and dump specs while continuing to run 2 tiles back and forth to avoid the miasma pools. The best special attack weapons for this in order are dragon claws, Voidwaker, burning claws, crystal halberd (final attack only), and dragon dagger.
• It is not completely necessary to kill the spawns in phase 3-1. Reduce his defence to 0 during phase 2, resetting spec energy with a home teleport if needed. Bring him to phase 3 and continue attacking him as he walks forward and roots. The animation is long enough that he will likely enter phase 3-2 as soon as the spawns appear. At this point, avoid the explosion and dump specs, which will likely all hit as his defence is still 0.
