Plantera

"The jungle grows restless..."

Plantera is a Hardmode Boss that can be fought after all three Mechanical Bosses (The Destroyer, Skeletron Prime, and The Twins) have been defeated. In the and, only one Mechanical Boss must be defeated.

Summoning
After all three Mechanical Bosses have been defeated (only one required in Mobile version), one or more Plantera's Bulbs will appear somewhere in the Underground Jungle. Destroying one of these bulbs requires a Pickaxe or a Drill, and upon doing so, Plantera will spawn immediately with the message, "Plantera has awoken!"

Attacks
Plantera moves through blocks. It uses long vines to grapple foreground blocks, which cause 60 damage on contact.

First stage
Plantera creeps after the player, firing pink Seeds and eventually green Poison Seeds. These fire more rapidly as Plantera takes more damage. Plantera also begins to spit large, bouncing thorn balls after taking a certain amount of damage.

Second stage
Once Plantera is brought down to half of its original health, it changes to its second form, with its pink bud falling away to reveal a thorn-filled mouth. In this form, Plantera moves quicker, and primarily attempts to make physical contact rather than fire ranged attacks.

Additionally:
 * It sprouts mouths that are attached via additional vines (called "Plantera's Tentacles").
 * It begins releasing floating pink spore projectiles that drift toward the player, similar to the spores released by the Giant Fungi Bulb.

Enraged behavior
Plantera only becomes "enraged" if it follows the player out of the Underground Jungle, to the surface, for instance. This causes it to gain significantly more damage, defense and movement speed, as well as changing its attack patterns and directly rushing the player with its body.

Attack types

 * [[File:Plantera Seed.png]] [[File:Poison Seed.png]] Seeds (first stage): Similar to the stingers of the Hornets. As of 1.3.0.1 update, these now travel through blocks. The green Poison Seeds are more deadly than the more frequently fired pink Seeds.
 * Thorn Ball.png Thorn Balls (first stage): Thorn balls are similar to the Spiky Ball weapon. These bounce around erratically through the Jungle and can overwhelm the player if they stay in the same area for too long, as well as deal large amounts of damage on contact. Plantera will not begin releasing thorn balls until it drops below around 24000 life. It will stop releasing the thorn balls once it enters the second stage, although the thorn balls previously released may linger for a bit.
 * Plantera's Hook.png Plantera's Hooks: The ends of Plantera's tentacles, which cling to surfaces and deal 60 damage on contact.
 * Plantera's Tentacle.png Plantera's Tentacles (second stage): Gnawing minions on "leashes", akin to smaller versions of The Hungry. They deal 60 damage and get in the way of the player's attacks, making piercing weapons more valuable. Relatively weak and easily killed with proper equipment.
 * [[File:Spore.png]] Spores (second stage): Similar to the Fungi Spores fired by the Giant Fungi Bulb. Travels through blocks. Easily destroyed, but deal 70 damage if touched.

Expert Mode
In expert mode there are a few significant differences in Plantera's attacks, aside from the default increased health and damage.

Phase 1
Plantera's seeds, that originally didn't travel through blocks, now travel through them and do increased damage. The thorn balls are also more common.

Phase 2
Plantera's tentacles, originally only attached to the body, now are attached to the Hooks and have increased in number (considering there are 3 more for each hook, there appears to be 9 extra tentacles). They also have more health than usual (including the default increased health). Plantera's body also does more damage and is faster than normal.

Aftermath
When Plantera is defeated for the first time, it will always drop a Grenade Launcher with Rocket I for ammo, as well as the Temple Key. A Temple Key drops each time Plantera is defeated thereafter. The Temple Key allows access to the Jungle Temple and Golem. The Temple Key can also be combined with Biome Key Molds to craft Biome Keys for access to Biome Chests in the and.

A status message saying "Screams are echoing from the dungeon" will appear, signaling that new, more difficult enemy types will begin spawning in the Dungeon (see details). These drop new weapons, accessories, and other useful items. Dungeon Spirits will begin to appear when enemies with more than 100 health are slain in the dungeon, which drop Ectoplasm, a new crafting material that offers access to the Pumpkin Moon and Frost Moon events, as well as the Spectre Bars used to craft Spectre armor and tool sets.

Additionally:
 * Hardmode Crimson, Corruption, and Hallow spread will be slowed down to 1/3 (33%) of their previous speed.
 * The Cyborg NPC becomes available.
 * The Truffle begins selling the Autohammer, used to craft Shroomite Bars for Shroomite armor and other endgame items.
 * The Traveling Merchant will begin selling the Pulse Bow.
 * The Witch Doctor begins selling several items related to minion summoning.

Tips

 * Excavate a sizable area to allow easier dodging before summoning Plantera.
 * Using a Gravitation Potion can help you avoid any further damage from spiky balls laying on the ground, as the spiky balls obey gravity and fall to the floor.
 * Plantera's Bulb can spawn in player-made Jungle Biomes, which can provide a slightly easier way to fight Plantera.
 * Narrow passages slow Plantera as it takes more time for it to grip the surrounding terrain.
 * Plantera spawns off-screen and is quite easy to outrun, which means if you intend for it to chase you, you will need to stop periodically or move much more slowly than normal.
 * Widening a bee hive in the underground jungle is a fast and effective way of making an arena for fighting Plantera.

Trivia

 * The name "Plantera" is a play on the title of American metal band Pantera, which is Cenx's favorite band. Plantera drops "The Axe", which looks similar to the Washburn and Dean electric guitars often used by late Pantera guitarist Dimebag Darrell. Plantera's music also features electric guitars.
 * On the the saving icon is one of the spiked balls that Plantera fires.

History

 * Added Expert Mode drop, Spore Sac.
