Acheron mammoth

Acheron mammoths are level 96 Slayer monsters. 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 make the level 99 Summoning pack mammoth Beast of Burden pouch.

Location
Several Acheron mammoths inhabit an iceberg that has been separated from Acheron, far north of the Fremennik Province. This can be accessed by using the large boat north-east of Rellekka, near the rock crabs.

Mechanics
Acheron mammoths have adrenaline and can use abilities. They also use simple melee abilities such as Smash, Sever, Freedom, and Pulverise. When using freedom, mammoths will announce it by shouting "Freedom!" Unlike the ability, the mammoth's freedom cannot clear bleed effects.

They have a ranged attack where they will grab a chunk of ice from the ground and launch it at the player's last location. If the player moves just as the ice chunk falls to the player's last position was thrown, they will take damage. The mammoth can still attack while preparing this attack so players should be wary of this.

They will stomp challengers that get under them for upwards of 3800 damage, with a bright red message in the game box stating that they have stomped you. Attempting to safe spot them will disable your prayers and deal up to 1500 damage. This is accompanied by the message "Your dishonourable conduct during the duel has angered the gods, who refuse to listen to your prayers any longer."

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 does work against this freeze.

Charge attack
Occasionally, the mammoths will stop attacking and have a charge-like animation. In addition, a blue bar will appear over the standard one and fill up within 5 seconds. As the info bar may block the view of the blue bar, it is advised to move it away from the screen and put somewhere that can be easily seen but not affect your interface. When the blue bar is filled, the mammoth will charge at your last position up to three times in a row, dealing up to 8000 damage per charge.

The mammoth is still vulnerable to attacks so if its health is low enough, players can kill the mammoth before it can charge again. The charge attack does melee damage, so it has a chance of missing, and is affected by protection prayers/curses.


 * Running
 * The charge is a simple area of effect attack. Moving out of the mammoth's path when it charges will avoid all damage. A simple way to avoid this is run perpendicular to its path as it is about to charge. The mammoth's initial location does not appear to be part of the charge path.


 * Devotion
 * Activating protect from or deflect melee and using the devotion ability will reduce damage from the attack completely. The 10 second timer of devotion is long enough to last 3 consecutive charges.


 * Tanking and healing
 * With a shield available, the first charge can be tanked as a normal attack, and equipping your shield, resonance can be used to provide high heals to restore lost life points. This method has its downsides, however. There is no lower limit to the damage the charge can deal, so it possible, for example, to take a 6,000 damage hit and then heal for only 500 life points.
 * If a mammoth performs a third charge, this will need to be avoided another way, advisably by simply running out of its path. If after the second charge you have full life points, you can also opt to simply endure this third hit; this may be risky if the attack hits too high.

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?

Trivia

 * Acheron mammoths were first mentioned in 2004 in a Behind the Scenes article as a future update, alongside the Lizardmen and many other updates, most of which made it into the game. A model was nevertheless made for them, although it was ultimately unused, only eventually appearing as a monster as part of Old School RuneScape's Wilderness Rejuvenation and first birthday celebration.
 * 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 .
