The Forgotten Temple

Live name: Plane of Earth B

Igneo, Metamorphos, Sedimentus
Igneo, Metamorphos, and Sedimentus is the first raid encounter within the Forgotten Temple. They are found at the 3-temple area just past the zone-in. At certain percentages one boss checks the other's hitpoints. If its hitpoints are more than 1% out of range (for example, Igneo is at 65% and checks Metamorphos. Metamorphos can be at 64%, 65%, or 66% HP) the checker will emote Target's form cracks as it loses its balance with the earth! and explode, causing 3255 damage to the raid. Most importantly, the boss will despawn (strikes itself for 1000000) and an earth elemental ("a powerless core") will spawn in its place. The core's HP does not matter throughout the fight, but they also do not drop loot.

Igneo checks Metamorphos at 95%, 65%, 35%, and 15%. (emote: Igneo assesses its balance with Metamorphos)

Metamorphos checks Sedimentus at 85%, 55%, 25%, and 10% (emote: Metamorphos assesses its balance with Sedimentus)

Sedimentus checks Igneo at 75%, 45%, 20%, and 5% (emote: Sedimentus assesses its balance with Igneo)
