Acheron mammoth icon

Acheron mammoths are monsters that require level 96 Slayer to kill. They were first revealed at RuneFest 2015, after being pitched on RuneLabs and being one of the November poll winners. They drop mammoth tusks, which can be used to summon the pack mammoth at level 99 Summoning.

Location

Several Acheron mammoths inhabit an iceberg that has been separated from Acheron, far north of the Fremennik Province. This can be reached by using the large Fremennik ship on the pier north-east of Rellekka. Do not confuse the ship with the other one nearby; the smaller ship takes you to the iceberg during Cold War.

Mechanics

Mammoths have especially high defence against non-stabbing weapons; for this reason, the Drygore rapier and the Khopesh of Tumeken are the most effective weapons to use against mammoths.

Acheron mammoths slowly gain adrenaline and can use the abilities Smash (disabling the player's protection prayers/curses), Sever, Freedom, and Pulverise along with a basic melee autoattack, which can deal around 2000 damage at maximum. When using Freedom, mammoths announce it by shouting "Freedom!". Unlike the player's Freedom, the one the mammoths use simply frees them from stuns and binds; it does not clear any bleeds.

The mammoths have a ranged attack where they grab a chunk of ice from the ground with their trunk before tossing it into the air, landing at the player's position when the mammoth started preparing the attack. This attack can be avoided by moving away from the tile the player was on when the mammoth first picked up the rock. It is best to dodge or Resonance the ice chunk, as it can deal over 4000 ranged damage with a 100% hit chance regardless of armour. They can use melee attacks during the ranged attack's animation.

They have a unique prayer deactivation mechanic they use if the player performs "dishonourable" conduct during the battle, which is performed by continuously running away from the mammoth and staying out of reach of its melee attacks. If such conduct is performed, the mammoth will throw 3 ice chunks at the player's position instead of one. If any of these ice chunks hit the player, a message will appear stating that "Your dishonourable conduct angers the gods, who refuse to listen to your prayers any longer.", disabling all prayers currently active (including Protect Item and Turmoil) and dealing heavy ranged damage.

Prayers can be immediately reactivated after being hit by the "dishonour" attack. However, it is possible for all 3 ice chunks to simultaneously deal damage to the player, potentially resulting in an instant death. Furthermore, players using weapons augmented with the Aftershock perk should be careful not to hit any other mammoths besides their current target with it; doing so can result in being attacked by the other mammoth's "dishonourable conduct" attack.

When fighting using Ranged or Magic attacks, mammoths will continuously use a ranged stunning attack. This will cause your run energy to be depleted, along with the deactivation of your prayers and a 5 second freeze. Freedom and Anticipation work against this freeze. It is recommended to fight them with melee so this attack does not occur.

Charge attack

Occasionally, the mammoths will stop attacking and have a charge-like animation. In addition, a blue bar will appear above the mammoth and fill up within 5 seconds.

Once the bar fills, the mammoth will charge up to 3 times in a row. Each charge can deal up to 8000 melee damage, and if Berserk or the Berserker aura is used, it is possible for the mammoth to instantly kill the player with one charge if it is not protected against.

The most effective way to reduce damage from the charge attack is to activate Resonance, which will heal the player to nearly full life points. The player should still be wary of any ranged attacks the mammoth may perform, since the charge animation will override their ranged animation. Protect from Melee or Deflect Melee. This will reduce the mammoth's damage to around 2000 per hit, and can be stacked with Devotion or Debilitate to further reduce damage.

The heavy damage of the ranged attack can severely harm or kill the player in conjunction with the charge attack, especially if the mammoth used the triple rock prayer deactivating attack or Smash. The mammoths can still be killed during their charge-up, preventing all damage from the charge.

Starting a fight

When initiating a fight with an Acheron mammoth, the player automatically says one of the following lines:

  • CHAAAAARGE!
  • En garde!
  • Good sir, I challenge you to a duel.
  • I challenge thee to a duel.
  • I mock your ancestors!
  • I'd throw down my gloves, but they're rather pricey.
  • Let's do this!
  • Mammoth! I challenge you!
  • Manners maketh man
  • Round one: FIGHT!

The mammoth will then respond with one of their lines respective to what the player said:

  • That's my job!
  • Ahaa as you wish.
  • I accept your challenge! or My name is...
  • I'm sorry you feel the need to throw your life away.
  • Yours are not even worthy of that.
  • You're going to need them to defeat me!
  • I trust you have a good note about how your remains will be handled?
  • Prepare to join your ancestors!
  • Are we going to stand here talking, or are we going to fight?
  • Erm... yes?

Named mammoths

If the "Mammoth! I challenge you!" option is said, the mammoth may say "My name is <name>!". When this happens, it will also change their name label to the name they said.

Known names include:

  • Anthony
  • Ashley
  • Daniel
  • Henrik
  • James
  • Liam
  • Luke
  • Nils
  • Thomas
  • Wing

Trivia

Mammoth Unused Model

The original, unused model of the mammoth from 2004.

Elite Mobs concept art - Mammoth

Concept art for an Acheron mammoth and its elite version. The elite version never made it into the game.

  • Acheron mammoths were first mentioned in 2004 in a Behind the Scenes article as a future update. A model was made for them, although it was ultimately unused.
  • They make small appearance in player-owned ports, as a Mammoth Head can be built at an icon hotspot.
  • The Mammoth was an option in a guaranteed content poll on 28 April 2008. It was a possibility for one of the future summoning familiars, although it was outvoted by the phoenix.
  • "Manners maketh man" and the reply "Are we going to stand here talking, or are we going to fight?" are a reference to the film Kingsman: The Secret Service.
  • "Round One: FIGHT!" may possibly be a reference to the Mortal Kombat series. It may also possibly be a reference to Street Fighter.
  • Before 28 November 2016, mammoths had a stomp attack used against players who moved under them that dealt over 3,000 typeless damage. The blue adrenaline bar that signifies their charge attack was also made more visible, as sometimes it would not appear until the attack actually commenced.
  • Mammoth tusks previously had a 1/25 drop rate.[2] This was changed to a guaranteed drop on 3 July 2017.
  • The mammoth name "Henrik" is likely a reference to Mod Shogun, who helped create them.
  • As of 1 February 2018, the highest kill count for this monster was 6,668 kills.[3]
    • This had increased to 10,321 by 6 May 2018.[4]
