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.

While Plantera is alive, its exclusive Music will play.

Summoning
After all three Mechanical Bosses have been defeated, Plantera's Bulbs will randomly spawn in the Underground Jungle. Destroying one of these bulbs requires a Pickaxe, Drill or the Clentaminator (with dark blue solution), and upon doing so, Plantera will spawn immediately. Plantera will also summon when using actuators under the bulb.

Attacks
Plantera moves through blocks slowly, using long vines to grapple foreground blocks, in the second phase Plantera grabs Background Walls.

First form
Plantera creeps after the player, firing pink Seeds and eventually green Poison Seeds, firing them more rapidly as it takes more damage. When its health nears the value at which it would change to its second form, it begins dispensing bouncing thorn balls.

Although Plantera emphasises its range, contact can still occur if it gets too close, causing 50 / damage.

Second form
Once Plantera is brought down to half of its original health, it changes to its second form: Its pink petals fall away to reveal a thorn-filled mouth. In this form, Plantera moves more aggressively and attempts to make contact. It also sprouts additional mouths that are attached via vines (called "Plantera's Tentacles"). Once all of the tentacles have been killed, they will never regrow, making Plantera much easier to fight.

Plantera will also release floating pink spore projectiles that drift towards 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, whether it be to the surface, to the Underworld, to a corrupted or hallowed part of the Underground Jungle, or to a completely different biome. This causes it to obtain double damage (quadruple in the second form), double defense and increased movement speed, as well as changing its attack patterns and directly rushing the player. Plantera's behavior returns to normal upon re-entry of the Underground Jungle biome.

Attack types

 * Plantera's Hook.png Plantera's Hooks: The ends of Plantera's tentacles, which cling to surfaces and deal 60 / damage on contact.
 * Plantera Seed (animated).gif Poison Seed (animated).gif Seeds (first stage): Similar to the stingers of the Hornets and Flower Pow. In expert mode, these can travel through blocks. The green Poison Seeds are more deadly than the more frequently fired Pink Seeds, but are not fired until Plantera's health depletes past 24000 / . Pink and Green seeds deal 22 / and 27 /  damage respectively.
 * 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 dealing 62 / damage on contact. Plantera will not begin releasing thorn balls until it drops below 80% of its 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 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. With 1000 /  HP they are relatively weak and easily killed with proper equipment.
 * 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 can and with increased damage. They also have limited homing capabilities.

The thorn balls are also more common and home in on the player.

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 appear 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
Plantera always drops a Temple Key, which grants access to the Jungle Temple and the Golem boss. In the, Temple Keys can also be combined with Biome Key Molds to craft Biome Keys; but in the , Biome Keys drop in their respective biomes and no longer require molds.

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 powerful new weapons, accessories, and other items. Dungeon Spirits will begin to appear when Dungeon enemies with more than 100 health are slain, which drop Ectoplasm, a new crafting material that offers access to the Pumpkin Moon and Frost Moon events, as well as.

For players on the, it is a good idea to keep the Jungle Key for crafting Biome Keys and enter the temple with actuators.

Additionally:
 * Hardmode Crimson, Corruption, and Hallow spread is slowed to 1/3 (33%) of their previous speed.
 * Biome Keys can now be used to open Biome Chests in the Dungeon (they can unlock Chests pre-Plantera on ).
 * The Cyborg NPC becomes available.
 * The Truffle begins selling the Autohammer, used to craft Shroomite Bars.
 * The Traveling Merchant begins selling the Pulse Bow.
 * The Witch Doctor begins selling several items related to Minion summoning (requires Pygmy Staff), as well as the Vial of Venom.
 * Butcher, Nailhead, Deadly Sphere, Psycho and Dr. Man Fly will start spawning during the Solar Eclipse.

Tips

 * Excavate a sizable area to allow easier dodging before summoning Plantera.
 * Using a Gravitation Potion can help the player avoid any further damage from spiky balls laying on the ground, as the spiky balls obey gravity and fall to the floor. Alternatively, the player can use an arena which has a large empty area at the bottom for spiky balls to bounce in, well below the player and out of harm's way.
 * 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 the player intends for Plantera to chase them, they 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 (but watch out for the Larva unless you want to intentionally summon Queen Bee).
 * If you have already beat Plantera, hooking up onto a block and use Vampire Knives can do continuous damage on it, but not doing any damage or knockback on the player even if it gets too close.This is only recommended on the first form and wearing heavy armor.
 * The Flamethrower could be considered for fighting Plantera due to the continuous stream of projectiles emitted, and is a pre-Plantera weapon which can easily be crafted after defeating Skeletron Prime.
 * A recommendation is Chlorophyte Arrow, as they bounce off walls, allowing the player to get multiple hits on Plantera.
 * Equipping a Cobalt Shield will help with melee attacks because Plantera won't knock the player away, but the player may receive more damage since Plantera can get closer.
 * Using Golden Shower to lower Plantera's defense is sure to make the fight less difficult. In addition, the Ichor debuff also allows you to make Plantera more visible, as it gives it a bright yellow shading.
 * Using a Cross Necklace may also help as it increases your time of invincibility after being hit.
 * Fighting Plantera on the surface may be easier than fighting it underground if you have a good ranged weapon and a long set of Minecart Tracks.
 * Summoning Queen Bee during the fight is a very easy way to gain a 200 HP heal that can be "left alone" until needed.
 * Using the Chlorophyte Shotbow with the Holy Arrow is quite effective.
 * Using Teleporters and a Death Sickle can be an easy way to beat Plantera. Be aware of Plantera's hooks.
 * On the Old-gen Console versions, if all players die while Plantera is alive, it will stay where the player died, so try to stay around a spawn point, player made or not.

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 is a tribute to the late Guitarist for Pantera, Dimebag Darrell. Also, the achievement for defeating Plantera is called "The Great Southern Plantkill" in reference to the Pantera album "The Great Southern Trendkill".
 * Plantera's music is a rock-and-roll/metal theme, likely because Plantera itself is a reference to the band Pantera. Parts of its music have a similar sound to the end of Pantera's song Domination.

 * On the the saving icon is one of the Thorn Balls that Plantera fires.
