'''Erosion''' is an [[Advanced]] [[map]] in ''[[Bloons TD 6]]'', introduced in [[Bloons TD 6 ~~v37~~.0|version 37.0]]. It takes place at an ice floe which gradually melts as rounds progress. A polar bear is present on the map, which moves to stay on solid ice every time a piece melts. The polar bear does not interact with towers or Bloons.

'''Erosion''' is an [[Advanced]] [[map]] in ''[[Bloons TD 6]]'', introduced in [[Update history:Bloons TD 6/Version 37.0|version 37.0]]. It takes place at an ice floe which gradually melts as rounds progress. A polar bear is present on the map, which moves to stay on solid ice every time a piece melts. The polar bear does not interact with towers or Bloons.

This map's concept [https://reddit.com/r/btd6/comments/suxvmx/btd6_map_concept_erosion/ was designed by /u/TheWiseTroll], for the "200k Map Contest Competition" held on /r/btd6, and it was selected as a winner along with [[Dark Dungeons]] and [[Covered Garden]].<ref>[https://old.reddit.com/r/btd6/comments/u0yyrg/part_2_of_the_200k_map_concept_competition/ https://reddit.com/r/btd6/comments/u0yyrg/part_2_of_the_200k_map_concept_competition/]</ref>

==Layout==

Erosion has 6 different paths, only one of which is active at a time. ~~At first~~, the ~~active~~ path ~~is the one at~~ the bottom left ~~corner~~.

Erosion has 6 different paths, with only one of which being active at a time. On round 1, this starts with the path in the bottom-left.

~~Starting on~~ round 18 and every 18 rounds after, the land between the current track and the next tracks will collapse , selling all land towers on the ice and changing the path to the next lane. [[Pat Fusty (BTD6)|Pat Fusty]], [[Ice Monkey (BTD6)|Ice Monkeys]], [[Mermonkey (BTD6)|Mermonkeys]], [[Sun Temple (BTD6)|Sun Temples]], and [[True Sun God (BTD6)|True Sun Gods]] are not sold and transform into water towers when the land under them erodes. The map reaches the top-right lane and stops eroding on round 90, and the round 90+ lane is the shortest lane out of any lane in any map that gives rewards in ''BTD6'' (only [[Blons]] has a shorter lane). [[Heli Pilot (BTD6)|Heli Pilots]] cannot be placed on the top-right section of this map ~~while~~ [[Banana Farm (BTD6)|Banana ~~Farms~~]] ~~could~~, ~~despite Heli Pilots having the smaller~~ footprint ~~out of the two~~.

At the end of round 17 and every 18 rounds after (35, 53, 71, 89), the land between the current track and the next tracks will collapse, selling all land towers on the ice and changing the path to the next lane. [[Pat Fusty (BTD6)|Pat Fusty]], [[Ice Monkey (BTD6)|Ice Monkeys]], [[Mermonkey (BTD6)|Mermonkeys]], [[Sun Temple (BTD6)|Sun Temples]], and [[True Sun God (BTD6)|True Sun Gods]] are not sold and transform into water towers when the land under them erodes. Additionally, any towers in range of an [[Arctic Wind (BTD6)|Arctic Wind]] or above's ice platforms will also not be sold. The map reaches the top-right lane and stops eroding on round 90, and the round 90+ lane is the shortest lane out of any lane in any map that gives rewards in ''BTD6'' (only [[Blons]] has a shorter lane). [[Heli Pilot (BTD6)|Heli Pilots]] cannot be placed on the top-right section of this map, despite having enough space to do so (can be observed by placing a [[Banana Farm (BTD6)|Banana Farm]], which has a larger footprint and can be placed).

[[Boss Bloon|Boss Bloons]] always appear on the third path, regardless of the round number.

==Strategy==

Erosion is not particularly difficult outside of [[CHIMPS]] mode~~, as~~ towers sold by the eroding mechanic give back cash, though ~~care must still~~ be ~~taken to avoid placing heroes~~ on ~~eroding~~ land. ~~This is not~~ the ~~case in CHIMPS. The~~ eroding mechanic, along with the extremely short length of the ~~round 90+~~ track, ~~make~~ Erosion ~~generally considered as an [[Expert]]-level, mis-categorized~~ map ~~that is only bested by [[X Factor]] in terms of the difficulty of Advanced maps~~. ~~Attempt to place~~ as few towers as possible outside of the ~~top-right~~ in CHIMPS, as they ~~will be sold for no money before the hardest rounds come~~. For the early game and mid-game, use global towers placed on the top-right or towers able to be teleported.

Erosion is not particularly difficult outside of [[CHIMPS]] mode since towers sold by the eroding mechanic give back cash, though Heroes shouldn't be placed on temporary land unless they can teleport away. However, the eroding mechanic, along with the extremely short length of the final track, makes Erosion a difficult Advanced map. Place as few towers as possible outside of the permanent platform in CHIMPS, as they don't give cash back once they sink. For the early game and mid-game, use global towers placed on the top-right or towers able to be teleported. Alternatively, Arctic Wind and its ice platforms can be used, now that itself is allowed to be placed on water.

===Recommended towers and upgrades===

Line 45:

Line 46:

|[[File:BTD6 CorvusPortrait.png|x50px]]

|His Spirit can pop Bloons from anywhere, and his Spear spell is very powerful throughout the early game. At level 7, he can use Spirit Walk to move to a new lane away from collapsing ice and constantly gain mana. During the mid-game, his Spellbook can save up titanic amounts of money for a solid tower that defeats the late-game, such as [[Carpet of Spikes (BTD6)|Carpet of Spikes]] and [[Bloon Exclusion Zone (BTD6)|Bloon Exclusion Zone]]. In the late-game, Corvus still has solid utility with Ancestral Might and Overload.

|-

|[[Dan D'Monke (BTD6)|Dan D'Monke]]

|[[File:BTD6 DanDMonkePortrait.png|x50px]]

|Similar to Corvus, Dan can use Reposition or Volant Strike at level 7 to teleport himself before the ice under him collapses, though he can't reach level 7 before the first ice platform collapses, and his short range prevents him from reaching the first path from the second ice platform even when transformed into the Masqued Macaque (though [[Aerial Attunement]] can alleviate this in the earlygame). His main strength on this map is that Reposition can also teleport other towers, allowing shorter-range towers that excel on single-lane maps (such as [[Spike Factory (BTD6)|Spike Factories]]) to last for the whole game without a [[Support Chinook (BTD6)|Support Chinook]].

|-

|[[Psi (BTD6)|Psi]]

|[[File:BTD6 PsiPortrait.png|x50px]]

|Psi's global ranged attacks and abilities make them useful starting in the early game onwards and provides a good source of support DPS that can make saving up for expensive win conditions easier.

|-

|[[Bloon Exclusion Zone (BTD6)|Bloon Exclusion Zone]]

|[[File:BTD6 005-DartlingGunner.png|x50px]]

|Bloon Exclusion Zone has a reasonable save-up because of the long length of the mid game tracks. Once afforded it easily beats the late game rounds with a source of lead popping.

|-

|[[Carpet of Spikes (BTD6)|Carpet of Spikes]]

Line 53:

Line 66:

|[[File:BTD6 200-MonkeySub.png|x50px]]

|This upgrade allows Monkey Subs to adapt to lane changes by attacking within the range of other towers. It is primarily used for the early game, with Airburst Darts coupled with this upgrade contributing significantly throughout.

|-

|[[Arctic Wind (BTD6)|Arctic Wind]]

|[[File:BTD6 030-IceMonkey.png|x50px]]

|Arctic Wind platforms are important if wanting to salvage land towers, especially for Round 90 and above, which offers little space, and opens room for larger towers including [[Heli Pilot (BTD6)|Heli Pilot]] (which artificially cannot be placed on the top-right island). Additionally, Arctic Wind offers Ceramic slowdown for a decently low cost.
