Lava Titan

The Lava Titan is a hardmode enemy located in the Obsidium biome which spawns after Ragnar is killed. It can pass through walls, and is immune to Lava and the On Fire! debuff. When it attacks, it becomes stationary then releases a ring of projectiles that rotate and expand outward.

Despite being similar to the counterpart elementals (Ice Golem and Sand Elemental), it does not need any atmospheric condition to spawn. It has a 100% chance to drop a Magmatic Cluster, useful in creating the Magmatic armor.
