Pull Carefully, Raid Safely
After the victory over Magmadar (thanks to fear protection from the dwarf priests, no danger) continues into the Molten Core, the raid will have to deal with numerous fire elementals, giants, and patrolling lava wogs as well as core hounds.
Typically, one does not want to defeat all enemies but rather clear a corridor up to Gehennas. However, this only succeeds if the raid stays together and pulls the trash packs one at a time into a safe area.
At the latest with Gehennas, one should then clean the area a bit more broadly without forgetting any of the patrols. Due to the ongoing rain of fire, players must constantly move during that boss fight. An additionally pulled core hound or a giant duo makes the seemingly easy fight significantly more dangerous.
Pull carefully and remove all trash generously; this applies throughout the entire instance. Many raids pull the next trash enemies into the cleared area after defeating Garr to avoid an early pull from Baron Geddon. Boss number 5 continuously moves in the next room.
