Behavior

The Magma Boss has 3 states: normal, split, and fleeing.

The normal state occurs when the Magma Boss is not in any other states. The split state occurs every time the boss has taken 32M Damage (at 128M , 96M , 64M , 32M ^[Confirm] and 0M ). The flee state occurs after the last split.

During the normal state, the Magma Boss can do the following:

Shoot a fireball at a nearby player every second, which deals Damage on hit.
Create a circle of fire particles on the ground.
Jump into the air and land in the circle of fire, crushing all players beneath.
- Before landing, the Magma Boss launches 3 projectiles towards the opposite side of the arena. Upon touching the ground, they create large areas of fire particles which deal Damage to players standing in them every 0.5 seconds. They disappear before the Magma Boss jumps again.

The "Damage Soaked" by the Magma Boss can be seen as a meter on the scoreboard. It can alter its damage increase per cycle if filled and can be filled multiple times over with different effects and thresholds:

Yellow is the basic requirement to enter the split phase. It increases the Magma Boss's damage by +20% Damage.
Orange is the second threshold. It increases damage by +25% Damage.
Red is the final threshold. It increases damage by +35% Damage.

The Magma Boss always jumps at least 3 times before entering its split state.

During the split state, the Magma Boss jumps to the center of the arena and splits into many Magma Glares and Unstable Magmas.

Magma Glares target the nearest player and shoots fireballs. They can also deal Damage on contact. Each Magma Glare targeting a player increases the damage taken from them and Unstable Magmas.
- This can be calculated with $DamageMultiplier = 2 * TargetingMagmaGlares$ . The maximum multiplier is 14.
Unstable Magmas jump towards the player to deal Damage on hit.

The scoreboard will have the "Kill the Magmas" meter showing the amount of mobs required to kill. Once filled, the Magma Boss will return to its normal state. It will announce in chat the amount of Damage increase as it reforms.

When the Magma Boss reaches a cumulative +100% Damage or more, it will enter its final flee state. During this state, the Magma Boss shrinks and is set to 10M Health. It runs away from players while shooting fireballs. As its Health decreases, it moves faster and continues to shrink.

Strategy

Ideally, multiple players should work together to efficiently defeat the boss. Since the player has a higher chance of receiving rare drops if they deal more damage than other players, many players attempt to maximize their DPS.

Bows are the best way to deal damage against the main boss, as well as being the safest. One of the most cost-effective setups to kill the Magma Boss consistently is using at least 2 pieces of Terror Armor and a Juju Shortbow as Hydra Strikes can damage the boss very effectively. The late game bow, the Terminator does an even better job and can consistently deal maximum damage per Normal phase to reach the max damage threshold. This allows a solo player to defeat the boss at the fastest time indistinguishable from cooperative play due to the aforementioned mandatory three jumps from the boss per cycle.

Note that Arrows can often bounce off the Magma Boss due to Minecraft mechanics.

Magic weapons can be used to deal damage during the Normal phase, but are not as effective as shortbows even if using a Hyperion with powerful armor. It is highly effective in clearing out mobs during the split and fleeing phase though.

Using a melee weapon is a much riskier strategy of damaging the boss, due to it being commonly guarded by the AOE attacks, and is harder to hit. Melee builds are also nearly useless during the Split phase as the magma cubes especially the Unstable Magma will certainly kill the player. It is not advised to undertake this strategy unless they have very effective armor such as Necron's Armor or Crimson Armor. If the player has a good bow, melee is not recommended outright.

When the boss splits into smaller cubes, players should go after the Glares, since they are the ones responsible for the massive multiplicative damage. If using the Hyperion, try using Wither Impact above them instead of directly towards them to reduce the chances of teleporting into them.

When entering its Fleeing phase, it will always first start moving diagonally towards negative-X and negative-Z (towards the Hellwisp area). Use the time when it's reforming to camp the spot as mage or to aim towards it as an archer to immediately kill it.

When the boss dies, each player gets separate drops. If a player quits the lobby, gets limboed, or exits the game when the items are dropped, they will not receive the items.

Trivia

The Magma Boss was the first boss added and revamped from an early-game boss to a late-game boss.
The Ember Rod used to be a drop from the Magma Boss but was later removed.
- Ember Fragments also used to drop from the Magma Boss, but have since been replaced with Rekindled Ember Fragments.
Contrary to popular belief, the player is not required to land the killing blow to have the Magma Boss count towards their Bestiary.
While an Aurora Staff does not work on the main boss, it does on Magma Glares and Unstable Magmas.
The Magma Boss is not affected by Derpy's double HP perk during its normal and fleeing states.
- The Magma Glares and Unstable Magmas, however, are.

Bugs

The Magma Boss occasionally gets stuck during the flee state, becoming immobile and invulnerable.
- This can possibly happen if the chunks are unloaded during the final split state.
- This can be fixed by pushing it into the lava so it goes through blocks to take suffocation damage.
- No loot will appear on its death if it stays in this bugged state for too long.
