Avaryss, the Unceasing

Avaryss, the Unceasing is an Avernic demon and one of the generals of Zamorak's army in The Heart. Along with Nymora, the Vengeful, she is part of the Twin Furies.

During the God Wars, she and her sisters hunted and killed those who broke their oaths with Zamorak. After Zamorak returned, they led a pack of hellhounds to hunt down the remaining Dragon Riders loyal to Zaros, eventually finding Morvannon and tearing her apart, even though she had changed sides. Satisfied with their work, they continued their services to Zamorak, although they would eventually learn many years later that Morvannon may have had an egg, since they all knew and expected the Illujanka to be infertile.

At some point after the God Wars, Avaryss' and Nymora's sister was killed by Gregorovic. The duo have continued their service for Zamorak, while searching for Gregorovic at the same time so they could exact their revenge.

When Zamorak returned to Gielinor in the Sixth Age he pointed out that it was possible that Morvannon's dragon Gorvek could have escaped with an egg. Though the sisters desired revenge on Gregorovic for their sister's murder, Zamorak refused to let them do so until they had eliminated the Ilujanka child. This eventually led them to The Heart where they met both Gregorovic and the Dragon Rider Vindicta, who had survived their genocide millennia ago.

Avaryss yells at Helwyr after the latter attempts to have his revenge on Gregorovic for killing his clansmen, stating that she and Nymora will get their revenge on him for killing their sister. After a short but heated discussion, the two call upon the forces of Zamorak to claim the Heart in his name.

Combat
During the fight with the Twin Furies, Nymora focuses on ranged attacks while Avaryss focuses on melee. On Challenge Mode, two fireballs are added to the arena which bounce around randomly and deal damage to anyone at their impact zone (signified with green arrows similar to Detonate).

The Twin Furies use several abilities which follow the same order but may start up randomly in each kill: Charge, AoE ranged then channeled bomb.


 * Charge: Avaryss will jump onto the walls and surge across in a straight line. Getting caught will result in up to 2000 melee damage and a one second stun. The damage can be blocked/negated, but on challenge mode, this drops the player's overhead prayers. Players should attack Nymora while avoiding Avaryss' charges.
 * Ceiling Collapse: Nymora flies to one of the 4x4 tiles (there are 16 of these), where she starts flying overhead and smashes at the cavern ceiling, dropping stalactites from above for rapid ranged damage. It will hit everywhere on the field except the 4x4 tile Nymora is flying over. Players should focus on Avaryss as Nymora is unattackable while performing the ability.
 * Channeled bomb: Nymora and Avaryss will channel their powers, flying into the middle of the room and lighting the outer ring on fire for massive damage to anyone caught in it. They energy will send small fire blasts for some small damage while the ability is channeled. Both sisters will take extra damage while charging up, so Berserk is highly recommended to quickly drop their health. Once the bar fills blue, they will unleash an explosion covering the unlit part of the area for massive damage. As the bar nears blue, the outside fires will be extinguished, so run out when very little of the blue bar is left.
 * If the sisters are killed while the bar is near complete blue, the explosion will still occur. Players should either eat up or run to the outer ring to avoid taking unnecessary damage.

After the channeled bomb, they will repeat the same mechanics again until death.

Halberd-style weapons such as the noxious scythe or dragon rider lance are highly recommended when fighting the furies to deal extra damage, as both sisters share their health pool and are treated as separate NPCs.

Drops
Avaryss' drops can be increased by 25%, 50%, 75% or 100% if the player gains reputation with the Zamorakian faction.

Trivia

 * Her name is a play on the word "avarice".
 * Prior to a patch on 4 April 2016, players were able to receive duplicate drops of the same pet if they did not own both Ava and Nylessa pets. E.g. Avaryss' braid could be dropped multiple times after the user unlocked the pet, but before they have unlocked Nylessa pet.
 * Prior to 18 April 2016, killing both the Twin Furies only granted 1 message for the Adventurer's Log. Now they both have a separate message.
