Guide:Plantera strategies

Plantera is a boss that can be spawned after defeating all three Mechanical bosses.

Spawn Condition
Plantera can only be spawned by breaking a, by a Pickaxe, Drill, or various other means.

She must then be killed within the Underground Jungle, otherwise she will become enraged.

The Fight
Plantera will attempt to chase after the player, always trying to make her main bulb overlap the player's space. This results in a very linear kiting fight. She moves fairly slowly when compared to a player with speed-boosting equipment. This means a player in a large enough arena can easily keep a distance, assuming they just keep moving. As such, a good arena can make the fight much easier. Do keep in mind that if your arena gets too large, the middle of it may no longer be detected as Underground Jungle. This can be avoided while maintaining a comfortably large arena by making the space more long and narrow rather than square (or by simply somewhat widening a natural jungle cave then letting the jungle grass grow back over the surface). Also, cutting the edge of the arena with notches rather than a clean edge produces more jungle grass tiles on the perimeter and helps to maintain the jungle biome recognition.

The second stage begins when Plantera reaches 50% remaining health. The pink petals fall off to reveal a ferocious green maw and Plantera's speed is greatly increased.

Currently, Plantera will enrage and gain more defense, attack more frequently and deal massive amounts of contact and ranged damage if the player leaves the Underground Jungle (including to go to the surface), so surface-level arena strategies are impractical. One exception is taking advantage of Plantera's need to "grapple" to move by building a large enough space that Plantera cannot grapple up after you, and then firing down upon her. However, Plantera can grapple onto background walls, and since they extend down to the underworld, you would have to clear them out first.

The player will want to focus on dodging attacks while shooting constantly at Plantera. Once Plantera reaches her second form, the player should be very wary and attempt to dodge Plantera's lunges.

Ranged characters should try to kill tentacles as soon as they appear. Due to the generally low defense of Ranger sets, getting caught by tentacles often will kill the player very quickly.

Terrain Preparation
The actual shape of your arena depends on how you want to fight:


 * For a player who wants to have plenty of evasive space, excavating around a screen's worth of space inside the Underground Jungle and filling it with rows of Platforms can work well.
 * For more aggressive players, a smaller space excavated right next to a bulb can work too.
 * Others will just use a stack of bombs to excavate a large area for flying and grappling.
 * One fairly simple arena is simply widening a natural jungle cave enough to dodge and kite. The player can kite Plantera back and forth running a figure-8 pattern.

Regardless, mobility is normally key during her battle, but enough of a damage output can kill her fast enough to make evasion less important.

Plantera's spike balls do significant damage and are used frequently during Plantera's first phase, however, they can only bounce off solid surfaces. If you do not mind taking the extra time, consider digging a hole at least 2 times deeper than you would use for the fight and stick to the top half of your arena (that is, your actual arena has a large space beneath it for the spike balls to fall into and stay away from you). Without the added threat of Plantera's spike balls, she is much easier to defeat.

Make sure the arena is not too big and empty, as taking out too many Mud blocks might turn the Underground Jungle into just regular caverns, enraging Plantera and making the fight much more difficult. Honey can be used for its regeneration, so you can make little pools for the regeneration benefit. If you have the Party Girl, you can buy Bubble Blocks, and make a small pocket to put honey in. Bring a Hammer to remove the jungle walls so that in Plantera's second phase, the hooks can only grapple on to the blocks so she cannot reach you with her hooks, and thus you will not take damage from them.

Gearing up
It is recommended to increase your maximum life to 500 before trying to tackle Plantera and later challenges after her defeat. are very common if many days have passed after defeating one of the Mechanical bosses.

Using a  and enough health regeneration and defense, the player is capable of enduring Plantera's damage for the short duration of the fight. You can use a  to decrease the boss' defense and a  and  for maximum healing. A  is also preferable to increase the player's damage output.

Teleportation trick
Make a long hallway, and place a Teleporter with a pressure plate on each end.

When she is climbing down toward you on one side, jump on the pressure plate used to activate the Teleporter. You will teleport to the other side, and Plantera will need to climb back at you.

Boomerang-type weapons can fly indefinitely when using a teleportation trick, though there are not many hardmode-effective boomerangs available. Before the boomerang returns, the player can teleport to the other end of the hall, and the boomerang will change directions and pierce enemies along the way.

Note that if the hallway is too long, Plantera will despawn. This was observed in a hallway as small as 200 tiles. If you use the mobile version, you should make the hallway around 125-150 tiles long, as Plantera will despawn within a shorter range of the player.

This method is more difficult in Expert mode, as her seeds can pass through blocks, all of her projectiles are now homing, and her 'mouths' spawn on her legs, closer to the player.

Tank and Claw
Plantera can be trivially beaten with the Fetid Baghnakhs and the Star Veil/Cross necklace (even with the melee speed nerf).

For armor you will want either very high defense or use the Hallowed/Titanium armor's set bonus. For accessories forgo wings/boots and minions you want to load up on melee speed (like the mechanical glove) and damage reduction (worm scarf, brain of confusion).

The fight: use your hook to attach to a wall near the bulb this prevents knockback and locks you in place. Break the bulb. Plantera will come right to you and sit on top of you. Hold down the attack key until she dies. That's it, You might have to use a potion mid-fight particularly on PC where the Baghnakhs are less powerful. This works even on Expert.

Firework Rockets
Plantera is particularly easy to lure into the path of Firework Rockets, making them good options for defeating her quickly. This requires only a large sum of money, and can kill Plantera in a matter of seconds.

If each firework deals its full 150 damage, 200 fireworks will suffice to kill her in Classic mode, 280 in Expert, and 357 in Master.

Minecart tracks
If you can locate a Plantera's bulb nearby a row of minecart tracks, you can easily annihilate Plantera at a distance while riding the tracks. This was observed with a natural generated minecart track, where Plantera was stuck in blocks due to the narrow hall and the varying heights.

Plantera can then be dodged at the end of the rail by using a bumper and ramming through her, suffering minimal loss on health.

This was done using a Chlorophyte Shotbow, along with Frost Armor and an Endless Quiver.

The pros being miminal terrain preparation, cons being depends on chance and rails may lead out of the jungle, resulting in an enraged Plantera.

Circle and run
This is a technique used by several youtubers in Expert mode, including Gellot.

Make an arena in the underground jungle about 2 screens wide and high with platforms, making sure to have the bottom row by platforms, letting the spiky balls she fires fall to the ground harmlessly. Nearby, place a Bed at one end of a long tunnel.

In Phase 1 of the fight, circle around Plantera using Wings, firing at her with projectiles.

When Phase 2 begins, use a Magic Mirror to teleport to your spawn point (making sure you don't go so far away as to make Plantera despawn) and progress down the tunnel, firing behind you as you go.

Bee

Using bees a player may use invincibility frames to become invincible. If they mine bee hive blocks until they are surrounded taking 1 damage in honey they can survive long enough to defeat Plantera or golem. To attack they must use a flying knife or weapon that does not have to return to player so the bees do not die.
