Demonic Pacts League/Echo bosses and echo equipment

Echo bosses are a returning system from Raging Echoes League that grant players the opportunity to fight challenging variants of existing bosses, targeting difficulty levels more suited to the power level that players attain during Leagues.

In order to access an echo boss, the player must acquire the region's echo orb from the non-echo variant of the boss and have it in their inventory while entering the boss area. Unlike Awakener's orbs, echo orbs are not consumed upon entry, and only one orb is needed for access to the boss for the entire League.

The regular bosses are guaranteed to drop echo orbs after exceeding 1x the nominal drop rate, and echo bosses are guaranteed to drop echo equipment after 2x the drop rate.

An echo of the Amoxliatl boss can be found in the Ruins of Tapoyauik. Infernal tecpatl can be obtained at a rate of 1/30 from Echo Amoxliatl. The tecpatl is a two handed weapon with 70 melee strength that can attack in all melee styles and hits twice. It also has 10% demonbane, providing increased accuracy and damage against demons. The special attack costs 50% energy and hits 4 times in quick succession with 25% increased max hit and accuracy. Damage is split depending on which hits pass accuracy.

Echo Cerberus returns with a new unique, the fang of the hound. Each hit of with the dagger has a 5% chance to cast Flames of Cerberus at the target. Flames of Cerberus is a fire elemental spell with a base max hit of 10 which can be increased with elemental weakness and magic strength. When the effect is triggered, the magic damage is dealt without needing to pass a second accuracy check. The effect also benefits from pacts and a creature's elemental fire weakness. The special attack costs 50% energy and performs an instant-hit with a guaranteed chance to cast Flames of Cerberus.

The echo variant of the thermonuclear smoke devil returns from Raging Echoes League. It requires 93 Slayer and a smoke devil slayer task. The echo variant does not require a slayer task once the Kandarin echo orb is obtained.

The devil's element returns as a unique drop and is a shield slot item that benefits elemental spells by adding a 30% elemental weakness against all elements in addition to any existing weaknesses.

The shadowflame quadrant can also be obtained by defeating the Echo thermonuclear smoke devil. It is a staff that, when on the standard spellbook, fires an additional spell attack that deals 40% of the damage of the first attack. The staff also acts as an infinite source of air, water, earth, and fire runes. When wielding the staff, spells treat all of a target's elemental weaknesses as equal to their highest weakness.

Can auto-cast spells from all spellbooks.

The echo variant of Hespori returns from Raging Echoes League with a new unique drop, the nature's recurve short bow. Upon a successful hit with nature's recurve, there is a 50% chance that the player's hitpoints and prayer points are restored by 10% of the damage dealt, rounded up. The bow can shoot all arrows.

The echo variant of the Dagannoth Kings returns from Raging Echoes League with a new unique drop, V's helm. When hit directly with 1 or more damage, the helmet provides a 5% chance to reduce that damage to 0. When the effect triggers, the player's next special attack within 60 seconds will cost no special attack energy. V's helm also counts as an imbued slayer helm.

The echo variant of the King Black Dragon returns from Raging Echoes League with a new unique drop, a crossbow called king's barrage. The crossbow always shoots 2 bolts at once. The first bolt counts as a crossbow attack, while the other counts as an ice attack which will always freeze the current target in place for 24 ticks (14.4 seconds). The freeze effect can be toggled on and off with the weapon.

The echo variant of the Grotesque Guardians returns from the Raging Echoes League with a new unique drop, the lithic sceptre. The sceptre gains up to 14 stacks of shatter every hit that lands on an enemy. The shatter stacks can be consumed with the special attack, dealing large damage. It is charged with earth and body runes.

The echo variant of the Kalphite Queen returns from the Raging Echoes League with the same unique, drygore blowpipe. The drygore retains its previous stats and passive, but also gained a 25% chance to burn targets on hit.

The echo variant of the Corrupted Hunllef returns from the Raging Echoes League with the same unique drop, the crystal blessing. The blessing provides increased damage and accuracy to melee and magic powered weapons along with an equipment bonus when combined with pieces of the crystal armour set.
