Plantera's main body appears to be a massive pink flower bulb, much like the plant that it was summoned from. It uses 3 vines to grab onto solid terrain to move. The vines do not inflict damage while the "claws" on the ends do. If the player were to make it chase them into the daylight, it would move faster than normal in the open daylight than underground. It shoots sharp leaves that do relatively little damage, which fire faster as its HP drops. There is also an intermediate stage at around a quarter of its HP lost, where it starts shooting pink spiked balls that bounce off of walls, making it almost suicidal to fight in tight spaces. The fire rate of the spiked balls also gets faster as it approaches the second stage.
After losing half of its HP, Plantera loses its petals to reveal a carnivorous plant-like body and a multitude of tentacle-like vines (besides the 3 used for movement) which behave similarly to The Hungry. It stops shooting projectiles at this stage and increases its speed and decreases in defense. This is a perfect time to use Ichor based weapons (Which needs the Crimson to be loaded in the player's world or brought from another world with Crimson in it) to decrease its defense even more, in order to kill it faster.
There are significant differences in Plantera between normal and Expert Mode worlds.
- Plantera is now faster, more damage resistant, and does more damage.
- Plantera's leaf attacks pass through walls in Expert Mode.
- The Spiky Thorn Balls now attempt to home in on the player.
- In addition to the tentacles that sprout from the main body, three more tentacles sprout on each arm (for a total of 9 extra).
- The tentacles are more durable than before.
- Plantera continues to be faster and deal more damage.
It is highly inadvisable to fight Plantera on the surface or outside of the Underground Jungle since it enrages and deals far more damage than usual. When enraged, Plantera is capable of killing the player instantly when hit, even with projectiles. It may be possible to defeat it using a surface technique, or similarly kiting it to a different biome (such as the Underworld), however top tier equipment and weapons would be required. Take care to ensure the location Plantera is engaged at isn't at the edge of the Underground Jungle or above a depth of 0 (use a Depth Meter or the GPS to check). Both of these things can trigger an unexpected enraged boss, significantly lowering any chance of survival regardless of the strategy. The use of auto-healing weapons is recommended as well, such as vampire knives, or mage weapons while the Spectre Armor (With hood) is equipped. (This can only work for farming Plantera, as both the Spectre armor and Vampire knives are only obtainable after Plantera is defeated).
This method is executed by simply excavating a large area in which the player can fight Plantera. This method will work well with most gear load-outs and can be a simple yet effective way of defeating it. By digging out a large circular space (The Underground Jungle has a multitude of similar spaces that only require a little cleaning up) and placing rows of platforms across its diameter, it becomes possible to apply different kinds of boss strategies such as Kiting. For this strategy, it is advisable that the player uses buff potions and places health regeneration items such as Campfires and Heart Lanterns down around the arena. Another arena setup is to build a grid in which the player can go up down left and right without using flight and if the player uses speed boosting accessories, they can increase speed when running because the player is not constantly flying. A fast and efficient weapon to defeat Plantera is the Clockwork Assault Rifle, as it fires faster than the Megashark when reforged and the first shot does not consume ammo. It also fires three round bursts, effectively better at ammunition conservation.
This method is recommended if there is no access to powerful equipment (such as gear that is required to defeat Plantera) yet and need a reasonably easy way of challenging this boss with a good chance to win.
On a side note, another way to kill it using the open area arena strategy is to lure Plantera into the Lihzahrd Temple. The player would have to first destroy all of the traps and spikes and after doing so the player would then summon Plantera and run down a pre-excavated tunnel leading into the Lihzahrd Temple where the player would then have the vital space to defeat Plantera.
For this method, a vertical shaft (see Hellevator) at least 3 blocks wide will be dug from the top of the Underground Jungle down to where lava pools begin to appear. Make sure neither end of the shaft is outside the biome. This doesn't take too long as mud mines up fairly quickly and the biome usually contains many open areas to which excess water can drain. The ideal location for this shaft would be in the center of the Jungle so that it can be quickly reached from anywhere a Plantera's Bulb is found. It could also be placed between two major Jungle cave systems in which the Bulb might spawn.
Items necessary for this method are Wings or other flight & slow-fall item and a Grappling Hook or similar item. Weapons used for this method are the best damage ranged weapons or spells available to the player. The Hallowed Repeater paired with Chlorophyte Arrows is sufficient. High Armor ratings, the Cross Necklace, and the Philosopher's Stone are not required but make this method easier.
To begin the battle, destroy a Plantera's Bulb and kite the boss to the hellevator, taking care not to get too far away causing it to despawn. Then fall/fly slowly down the shaft while Plantera chases the player, constantly shooting it with ranged weapons or spells. If it begins to get too far away, attach to the wall with the grappling device until it catches up, then resume slow-falling, shooting all the while. When the bottom is reached, simply fly back up through the shaft and attach to the wall to shoot Plantera as it catches up. When the top is reached, fall/fly back down and continue as before. Plantera doesn't follow the player in straight lines, so many of its attacks will miss since they do not pass through the walls.
This method works very well for Plantera's second form if it is dealing too much damage for the player to keep up healing while using the Tank method without Vampire Knives.
Teleporter Tunnel Method
An easy but expensive way to beat Plantera is by digging a long horizontal tunnel in the jungle, and attaching two Teleporters on both sides. Then, using a Megashark with Crystal Bullets or, for end-game players, the Terra Blade is also recommended. Shoot it while it approaches and teleport to the other side when it gets too close. Repeat the process until it dies. Hallowed Armor or better should be used since this method does not guarantee complete safety. Also, any extra damage items will speed up the process. Otherwise, nothing else is needed for this method. Other viable weapons for this method would be the Golden Shower or Ichor Bullets paired with a Megashark or better. Beware, Plantera will despawn after teleporting if the tunnel is longer than 150 blocks.
Circle Spear Method
The player should make a giant circle, have wings and Hallowed Armor on or better, and have a Mushroom Spear. To implement the core function of this strategy, the player will have to rapidly jab at Plantera with the spear while flying circles around it, being careful to avoid getting hit. This method takes around 5-7 minutes to complete the battle with.
Vampire Knives Method
The player clears out a large slab of the underground jungle maybe 100x100 or, to be safe, 300x300. Have a lot of platforms so the player can jump or fly straight through the platforms then fall as fast. When the player has done this they can put heart lanterns and campfires around the arena (if they so wish, it is not needed because the vampire knives heal hp fast). Then the player is ready to go and beat Plantera with vampire knives.
(Please note that this method can only be accomplished after Plantera has been defeated once due to the crimson chest only being able to be unlocked legitimately in a hardmode dungeon).
Deathbox Strategy (Mobile/Old-Gen Console only)
Build a house near a Plantera bulb with a bed. Set the player's spawn point there. No matter how many times the player dies Plantera won't despawn.
- As of 22.214.171.124, hardmode Dungeon enemies now only spawn when Plantera is defeated at least once in the same world.
- Upon defeating Plantera for the first time in a world, the message will display:"Screams are echoing from the dungeon..." This tells the player that Hard Mode monsters will now spawn in the Dungeon.
- In addition to this, Rocket-Based weapons are now available, and the Cyborg NPC moves in to sell the player Rockets.
- Be cautious when replacing the Underground Jungle with another biome using the Clentaminator. This can also break any Plantera's Bulbs in the firing line, summoning Plantera, and causing it to enrage instantly upon entering the new biome.
- The bulb can only be destroyed by explosives, Pickaxes, and Drills, and the Clentaminator.
- When Mushroom Grass Seeds are used under one of the mud blocks under Plantera's Bulb, it can summon the boss.
- The first time Plantera is defeated in a world, it will always drop the grenade launcher. The only way to get the other special drops is to summon and defeat it again.
- Every time Plantera is defeated, she will always drop a Temple Key, which is used to enter the Temple, and on old versions of Terraria its also used as a part to craft Biome Keys.
- Defeating Plantera while she's enraged does not wield extra drops or increase the chances of other drops.
- If Plantera is spawned and has no surface to grapple onto, she will keep slowly floating up to the Space Layer until she finds a block to grapple onto.
- It has been stated that Plantera's name is a reference to one of Cenx's favorite metal band, Pantera, which is an explanation to why it drops The Axe, a guitar from the same band.
- Redigit stated on Twitter that Plantera's theme is the "most epic thing in game".
- In Swedish, the term "Plantera" means "Planting", as in planting a plant.
- On the console versions, the spiky ball projectiles that Plantera shoots are used in the loading screen/saving sprite.
- Cenx has stated that Plantera is a female.
- Plantera's Bulb may spawn very near the edge between Jungle and Underground Jungle, causing Plantera to enrage immediately when the bulb is broken, making it harder to kill. Therefore, if a bulb spawns in such location, try not to break it. More bulbs spawn in other areas anyways.
- Plantera may instantly despawn if a player moves away from the area they were was indirectly after breaking the bulb. To avoid this, the player must stay still until one of Plantera's hooks arrive on-screen.
- Sometimes Plantera can spawn enraged, even in the underground jungle, leading inexperienced players to believe this is the default mode of Plantera. It's unknown why this bug may happen.
- Plantera's Bulb may spawn in a Non-Jungle biome, making Plantera despawn instantly if the Bulb is broken.
- Sometimes when Plantera's Bulb is broken with a Bomb, Plantera may not spawn.Verify
- It is possible for some parts of the bulb to be missing, and when broken may or may not spawn Plantera.
- Fixed a bug where the "Plantera Beaten" flag would not set properly for non-English users.
- The Axe drop chance increased from 0.5% (1:200) to 2% (1:50).
- Biome Keys are now unable to be used until Plantera has been defeated.
- Now drops the Seedler.
- In Expert Mode, now drops the Spore Sac and Seed attacks will travel through blocks.
- Now despawns when all players have been killed.
