Zombot Frost Wanderer

Zombot Frost Wanderer is the boss in Blizzard Peaks and the third corrupted boss in Plants vs. Zombies: Lost World, appearing on Level 4B. The Zombot Frost Wanderer can slowly grow a mini-whirlwind at their position before they release a flurry of ice shards from the whirlwind and down the two lanes that are adjacent to each other that the Zombot occupies, annihilating all plants and zombies there (similar to how the Zombots in Plants vs. Zombies 2 are able to defeat all plants and zombies in the lanes they occupy). The Zombot Frost Wanderer is able to exhale special chilling winds that don't have any freezing or chilling effects, but can form ice armour that is randomly given to zombies (any zombie can get this armour, including the non-basic variants, albeit the armour's appearance may vary between different zombies). This armour can absorb 480 DPS, but Gargantuars and Giga-Gargantuars, this armour absorbs 960 DPS instead, and, additionally, this armour can also be melted by Hot Potato and deal an additional 100 DPS of damage to the zombie who was equipping it. The Zombot Frost Wanderer can also pierce the ground with their ice claws to cause 3 to 5 ice spikes to emerge from the ground to impale random plants on the lawn and defeat them. These ice spikes will remain permanently on the lawn and can block attacks, and are able to absorb as much damage as those ice blocks that contain frozen plants (Hot Potato can also be placed on these ice spikes to melt them). Like other corrupted Zombots, Zombot Frost Wanderer can bend reality and create rifts similarly to how this occurs during levels in level path E's (more about level paths here). See more about the possible reality rifts Zombot Frost Wanderer can create in the Reality rifts section of this page. Due to the difficulty of the fight against this Zombot, the conveyor belt in the boss level will supply seed packets somewhat faster than usual.

Zombot Frost Wanderer was not actually the first name Dr. Zomboss wanted to give to this Zombot. Being the final 'guardian' left to get past before reaching the area where The Sanctuary was hidden, Dr. Zomboss knew he had to make something big. After initially coming up with the name Zombot Frost Walker, Dr. Zomboss got to work. After hours of putting his knowledge of Zombotics and corrupted energy to the test, the Zombot had finally come to life. What prompted the name change? Well... why would a Zombot called a Walker have no feet?
==Reality rifts==
Zombot Frost Wanderer can use their corrupted energy to create reality rifts. These rifts, unlike those from levels in level path E, are temporary, and each will only take place during certain phases of the boss fight (see the Phases section of this page for this). The following are the possible rifts Zombot Frost Wanderer can create:
*Avalanche rift - Avalanches now shuffle plant and zombie positions on the lawn rather than wiping them out (plants and zombies that are not caught in the same avalanche section will not swap positions with each other, where one section consists of adjacent columns occupied by the avalanche).
*Blizzard rift - Blizzards are more frequent, but blow in random directions (either from the left as normally, or from the right, from upwards or from downwards), pushing zombies one tile towards the direction they blow in.
*Sun rift - Sun now falls from the sky very rapidly and seed packets now require sun to plant, disabling the conveyor belt.
==Phases==
The Zombot Frost Wanderer is able to perform one of the following actions:
*It will create a portal using corrupted energy to summon zombies. The types of zombies that come out from the portal depend on the phase.
*It can pierce the ground with their claws to impale random plants on the lawn with ice spikes. These ice spikes will remain permanently on the lawn to block attacks, and can absorb the same amount of damage as ice blocks (that contain frozen plants) before they are destroyed. Hot Potato can also melt these ice spikes to get rid of them.
*It can exhale a special chilling wind that covers a random area of the lawn, randomly giving zombies ice armour that can absorb an extra 480 DPS (Gargantuars and Giga-Gargantuars get an extra 960 DPS instead). Any zombie in the level can gain ice armour, with the appearance of said armour varying between different zombies. Hot Potato can also melt this armour while damaging the zombie that was equipping said armour for 100 DPS.
*The Zombot can slowly form a small whirlwind of ice before they cause a flurry of ice shards to be released from said whirlwind down the two lanes it occupies, annihilating all plants and zombies present in those lanes.
**Most Plant Food effects can stop the Zombot while they are forming their whirlwind.
*The Zombot can use its corrupted energy to create reality rifts that last for the duration of one or more phases (refer to the table and the Reality rifts section of this page to know the details).

==Strategies==
Just like most Zombots from PvZ2, Zombot Frost Wanderer has the ability to take out two whole lanes of plants. As the Zombot will take time to do this by growing a small whirlwind, during this duration, use a plant's Plant Food power to damage the Zombot to prevent them from releasing their ice shards from their whirlwind. Due to Plant Food being the only way to stop this attack, it is recommended to save up Plant Food for situations like these, but, however, even if you don’t happen to have Plant Food, the damage can still be compensated for, since the zombies in the same lanes will also get taken out. Plus, with a conveyor belt supplying seeds, you can repair the damage done quickly. The Zombot Frost Wanderer's ability to give random zombies ice armour through their special chilling winds and as well as their ability to create permanent ice spikes can be tricky to deal with, as it puts more pressure on your defenses as they have to use more firepower in order to get rid of the spikes and the armour. Although Hot Potato can help a lot in these situations by melting the spikes and the armour, you'll need to remember that the conveyor belt can only supply so many Hot Potatoes at once, so using them too frequently may consequently be burdening for you if you need to use them again in an emergency situation, so make sure to conserve your Hot Potatoes as much as possible and only use them when you really need to. As mentioned previously, in order to handle the spikes and the armour that the Zombot creates, you'll need to try to use more firepower to get rid of them, so making sure you effectively use the plants provided to you in the level is needed. Usage of Ice Sage and Loudspeaker in this boss level is key, as Ice Sage needs to harness energy from nearby ice plants to make him stronger, and Loudspeaker can also help to speed up adjacent plants, and so the placements of these two plants in your defenses can make a really big difference. As a side note regarding the importance of these two plants, try to keep at least some of them away from the columns which would be affected by avalanches if they arrive so you won't need to wait for the conveyor belt to re-supply all of them (Living Stone is not given in this boss fight). As a corrupted Zombot, you'll also need to beware of Zombot Frost Wanderer's reality rifts. The avalanche rift may end up making your defenses really messy by shuffling the positions of your plants, potentially making it worse in fighting the oncoming zombies. One thing you can do is to try to limit most of your important plants to be planted only within the columns that are not affected by avalanches (e.g. Ice Sage and Loudspeaker whose positionings can make a difference, and Treeze who is important for being the frontline of your defense), while using the other avalanche-affected columns (mostly) only for the less important plants. For the blizzard rift, you just need to make sure your defense is prepared to counter zombies if they come too close to your defenses or if they switch lanes (so having a strong defensive frontline and having plants prepared to take zombies down on all lanes), which is something you can build up during the first phase of the fight. Additionally, because of the more frequent blizzards, you'll need to make sure that you've given Bur Coats to most of the plants that need it in your defense (or have at least placed the vulnerable plants next to ice plants to "warm" them), prioritising the ones that are not located in avalanche columns, as the avalanche rift is not activated alongside these rifts so any plants you've placed in avalanche columns will most likely get wiped out sooner or later. The sun rift in the final phase may probably be the most dangerous rift out of the others, as this rift will take away your conveyor belt and force you to use seed packets like in regular levels. Although sun drops much faster, you'll still need to make sure you spend your sun wisely and, additionally, you will also now need to wait for your seed packets to recharge rather than waiting for them to arrive in the conveyor belt. Because of this, your defense will also need to be very prepared before these rifts activate, so try to make sure that any plants engulfed by avalanches in the previous phase are replaced as soon as possible before the final phase starts. The avalanche rift that is also activated during the final phase should also help to make it less punishing when any of your plants get engulfed by avalanches, as you won't necessarily have to replant them with your seed packets (but, of course, keep in mind the strategy of dealing with this rift like during the first phase of the boss fight).
