Summoning
To summon Igneothorn, the player must find one of the Igneothorn Bulbs scattered throughout the second fourth of the Hellish Dungeon (once the world has entered War Mode). Once the bulb has been broken with a hammer, Igneothorn will appear and the fight will begin.

Fight
Igneothorn's fight is very akin to that of Plantera, but with a more defense-based Earth-theme. There are 2 stages plus an Expert-Mode only stage 3.

Stage 1:
Igneothorn is rather aggressive in stage 1, moving slowly but surely, spitting large boulders at the player. The boulders, after 5 seconds, explode into several high-velocity rock shards. It will relocate its hooks often and regularly rush the player, attempting to deal melee damage.

Stage 2:
Once the boss has reached 1/2 health, it will enter stage 2. In stage 2, the boss gains a speed boost, loses defense, and gains a new attack. It now has the ability to spew a thick stream of gravel at the player. In addition, its hooks will now grow a root system wherever they land, raising rocky spikes from the ground that are capable of damaging any player that stands on them.

Stage 3 (Expert Mode Only):
In Expert Mode, the boss, once it reaches 0 HP, will regenerate 400,000 HP back and begin to fight with a renewed vigor.
