Alchemical Speed-Runner is a grandmaster combat achievement which requires the player to kill the Alchemical Hydra in under 1 minute and 20 seconds.
The achievement requires 1100 damage to be dealt in 133 ticks, requiring an average damage of 33 for 4-tick weapons such as Bow of Faerdhinen, and 41.35 for 5-tick weapons such as Twisted bow.
Strategy
The hydra's massive health pool and high Magic level make the Twisted bow the optimal weapon to complete the task, and Dragon claws are helpful in bursting down a phase. With good gear and enough luck, it is possible to complete with dragon hunter lance or even a toxic blowpipe.
To save time:
- Lure the hydra to each respective chemical pool as soon as possible, blue and red phases should start with hydra already standing on the respective pools to be de-buffed.
- The blue phase should be ended as fast as possible, as getting hit by one of the lightning strikes will bind and damage the player for ~25.
- Clearing the fire phase early avoids unnecessary damage to the player and lost time from the knockback.
- Avoid attack delays by using Guthix rests throughout the fight.
- 80 seconds allows for 4 optimal Vengeance hits, and requires high health at the start of enrage phase:
- Vengeance before entering, there's a 50% chance the first attack will be prayed correctly. If prayed correctly, hold until green phase acid pool removes damage reduction.
- Vengeance after first vengeance is consumed, pray correctly to hold and use in blue phase.
- Vengeance after second vengeance is consumed in blue phase, pray correctly to hold until enrage phase.
- Vengeance after third vengeance is consumed in enrage phase, player will take a second large hit and will need to avoid further damage or risk death.
