Boss Bloon Event: Difference between revisions

'''Boss Bloon Events''', also called '''Boss Events''', are weekly events in ''[[Bloons TD 6]]'' introduced in [[Bloons TD 6 v27.0|version 27.0]] where players encounter [[Boss Bloon]]s in a modified version of a [[Boss Challenge]]. In each event, one of the Boss Bloons is selected to appear on a [[map]], possibly with some [[Challenge modifier|challenge modifiers]] such as tower and hero restrictions. Victory is achieved in a Boss Bloon Event by defeating all five tiers of the boss. The Elite version of the boss may not be attempted in single-player until tier 5 of the Normal boss is defeated.

The Boss Bloon Event usually runs weekly, starting {{hover|early Saturday|Saturday at 08:00:00 UTC}} and ending {{hover|early Thursday|Thursday at 03:00:00 UTC}}. There are sometimes exceptions to this schedule: for example, events typically end earlier right before a major update. Boss Bloon Events generally cycle between the six available bosses in the following order: [[Bloonarius (BTD6)|Bloonarius]], [[Lych (BTD6)|Lych]], [[Vortex (BTD6)|Vortex]], [[Dreadbloon (BTD6)|Dreadbloon]], [[Phayze]], and [[Blastapopoulos (BTD6)|Blastapopoulos]]. Directly after an update that releases a new boss, these events feature the new boss for 4 weeks before returning to the regular order.

Since [[Bloons TD 6 v31.0|version 31.0]], during the final hour of the event, players on Ranked Mode cannot start a new run and the those who are in the middle of a game will not be able to resume if they exit the game. This was done with the intention of preventing scores from being submitted past the ending time of the event.

Each Boss Bloon Event has a different ruleset, which determines many aspects of gameplay including the type of Boss encountered and the map it is played on. In addition, there are many modifiers which may be in place during each event. Possible modifiers include those available in the [[Challenge Editor]], plus some specific to Boss Bloon Events.

|Usually Medium, but [[Easy]], [[Hard]], and [[Impoppable (BTD6)|Impoppable]] have all been used before in Boss Bloon Events.

|Usually Standard. [[Half Cash]], [[Alternate Bloons Rounds]], and [[Reverse (BTD6)|Reverse]] have been used before in Boss Bloon Events.

|Has been set as high as 39, but never higher.

|In co-op mode, each player has their own monkey limit. For example if Max Monkeys is 10, each player may place up to 10 monkeys for a maximum of 40 monkeys on the screen in 4 player co-op.

|All [[Paragon|Paragons]] count toward this limit regardless of which player placed it.

|Usually 110% if the boss is Vortex. Does not affect the boss.

|Boss Bloon Events use a different system than regular games, allowing the player to go back to the previous checkpoint at any time, or retry the last round when they lose. A checkpoint is reached every 20 rounds.

Maps of all difficulties including the special [[Protect The Yacht]] map have been used in events, but [[Beginner]] maps are selected most often. The Elite version of the boss may feature different modifiers and restrictions than the Normal version, but is always played on the same map.

The tier 1 boss appears on round 40, and the successive tiers appear every 20 rounds until the final tier 5 boss spawns on round 120. A banner will be visible at the top of the screen indicating the number of rounds remaining until the boss appears and while it is on the screen, the banner is replaced by the boss' health bar. Players receive rewards after beating each tier, but if the boss reaches the exit or is not beaten after 20 rounds since spawning, a defeat will occur even if no lives are lost. While the boss is on the screen, there are no breaks between rounds even if Auto Start is disabled. All bosses feature a [[Bloonarius (BTD6)#Round changes|custom round]] on most of the rounds on which they spawn (Round 40, 60, 80 and 100). In addition to this, [[Lych#Round changes|Lych]], [[Vortex (BTD6)#Round changes|Vortex]] and [[Dreadbloon (BTD6)#Rounds|Dreadbloon]] feature changes on other rounds as well (see the page for each boss for details).

After round 20, the player can choose to restart the game at the last round multiple of 20 they have passed (Round 20, 40, 60, 80, 100 or 120) at the cost of some [[Monkey Money]]. The cost starts at {{BTD6 mm|100}} and increases by an additional {{BTD6 mm|100}} every 20 rounds. If the player is defeated they may also choose to restart the last round by paying twice the amount of the 20 round reset. Exiting the the game and returning only restarts the current round with no additional penalties.

Boss Bloon Events can also be played in Co-op mode with in public or private lobbies. The rules for cash sharing are the same as in regular Co-op modes. Unlike regular Co-op, no additional starting cash is granted, and the map split cannot be changed from the map's default split.

Before starting a game, players may check a box in the lower left part of the screen to play in Ranked Mode, in which players compete to place as high as possible on a leaderboard for additional prizes. This mode disables Insta Monkeys, Powers and in-app purchases to prevent pay-to-win scenarios. Everything else regarding to the event (Boss, Map, modifiers and restrictions) is the same as non-ranked mode.

* '''Least Cash''': A counter is increased by the amount of cash spent when a tower is placed or an upgrade is purchased. Paying cash to purchase items at [[Geraldo (BTD6)|Geraldo's Shop]] or using map features such as [[Removable|removing obstacles]] or [[Gizmo|gizmos]] also increase the score.

* '''Least Tiers''': A counter is increased by one every time a tower is placed or a upgrade is purchased including Hero levels and [[Paragon]] upgrades. Gizmos and [[Sub-towers]] such as Geraldo's shop items and the Marine deployed by the [[Special Poperations (BTD6)|Special Poperations]] ability do not increase the score.

There is also a penalty timer (shown in red below the boss banner/health bar) that penalizes players for taking too long to beat non-boss rounds. Every round, <code>10 + Round Number × 0.25</code> seconds after the last Bloon of a round enters the screen, a timer begins to count up until all Bloons from that round are popped.  At the end of the game, all accumulated time in the penalty timer is added to the regular Boss timer. The cooldown of cash-generating abilities is paused while the penalty timer is active, even in non-Ranked mode (where the timer does not appear), to prevent abuse and weaken strategies such as [[IMF Loan (BTD6)|IMF Loan]] farming.

Every week, one of the three scoring types is selected for Normal and Elite and all players who defeat the boss will be ranked according to it. The scores for Normal and Elite bosses are independent from each other, and since [[Bloons TD 6 v44.0|version 44.0]], they can have a different scoring type on the same week. Regardless of the type used, the timer described above will appear because it is used as the tie-breaker in Least Cash and Least Tiers rankings.

Ranked Mode can also be played in Co-op mode and the scores of each size of team is recorded in a independent leaderboard (there are different rankings for teams of 2, 3 or 4 players). If a player has scores in multiple leaderboards for the same Boss difficulty, only the highest prize will be earned.

In addition to the global ranking, players who defeat the boss in Ranked Mode are placed automatically in a Leaderboard with pool of up to 100 players known as the Mini-Boss. Players gain additional prizes based on their ranking within the Mini-Boss. Co-op and solo players may be placed in the same Mini-Boss.

Boss Bloon Events are usually harder than [[Boss Challenge|Boss Challenges]], due modifiers and restrictions that can be applied each week, but in general anything that works for Boss Challenge may also work in events.

The most important advice for defeating Bosses, especially Elite versions, is to generate additional [[Cash|income]] (a.k.a. farming) and start doing so as early as possible. Notice that Normal Bosses can sometimes be beaten without additional income and a proper defense strategy but Elite Bosses are just impossible without farming.

[[Benjamin (BTD6)|Benjamin]] or [[Geraldo (BTD6)|Geraldo]] are the most used [[Hero|Heroes]] in Boss Bloon Events thanks to having methods of generating extra income that can be used to accelerate early game farms. If they are not available the Hero choice falls into two categories: Heroes that can carry the early game on their own to focus on farming (ex. [[Quincy (BTD6)|Quincy]], [[Sauda (BTD6)|Sauda]]) or Heroes that have good synergy with towers which can defend the early and middle tiers (ex. [[Admiral Brickell (BTD6)|Admiral Brickell]] + [[Triple Guns (BTD6)|Triple Guns]] or [[Adora (BTD6)|Adora]] + [[Sun Avatar (BTD6)|Sun Avatars]]).

 

Early farming can be is usually done with strategies such as [[Marketplace (BTD6)|Marketplace]] spam or the ''Miniopolis'' ([[Monkeyopolis (BTD6)|Monkeyopolis]] with one farm sacrifice). The latter is more efficient but depends much more heavily on Monkey Knowledge, featuring a 2-3-0 [[Monkey Bank (BTD6)|Monkey Bank]] obtained early, collected when full, and upgraded to [[IMF Loan (BTD6)|IMF Loan]] with the rest of the money deposited. When the IMF Loan becomes nearly or completely full, it is collected, a [[Monkey Commerce (BTD6)|Monkey Commerce]] is purchased to discount a [[Monkey Town (BTD6)|Monkey Town]] near the IMF Loan, the Monkey Commerce is sold, and finally the IMF Loan's ability is used to upgrade the Monkey Town into Monkeyopolis. If using Geraldo, purchase [[Rare Quincy Action Figure]] early, spam 2-0-0 [[Greater Production (BTD6)|Greater Productions]], and sell the NFT and all farms after Round 30 ends to get a Monkeyopolis (discounted by 3 Monkey Commerces) absorbing a 0-0-0 [[Banana Farm (BTD6)|Banana Farm]]. Additional income generating towers like [[Bloon Trap (BTD6)|Bloon Trap]] and [[Rubber to Gold (BTD6)|Rubber to Gold]] are also useful in this stage of the game. The use of [[Fast Track Mode]] is discouraged as the player will have less rounds to farm.

 

 

 

Other towers that can be used for income generation are [[Bloon Trap (BTD6)|Bloon Trap]], [[Rubber to Gold (BTD6)|Rubber to Gold]], [[Merchantman (BTD6)|Merchantman]], [[Supply Drop (BTD6)|Supply Drop]], [[Support Chinook (BTD6)|Support Chinook]], [[Jungle's Bounty (BTD6)|Jungle's Bounty]] and [[Sun Temple (BTD6)|Sun Temple]] with support sacrifices. This is important to keep in mind in the case Banana Farms are restricted.

 

Listing specific towers to defend each boss tier is difficult because their success will depend a lot on which Boss, Map or modifiers are active but commonly used options for Elite bosses are:

 

* Tier 3: Several of the Tier 2 options, cheaper Paragons like [[Apex Plasma Master]] or [[Glaive Dominus]] (Degree 1 is usually enough but 20 is recommended), or even spamming some tier 3/4 towers with buffs from [[Call to Arms (BTD6)|Call to Arms]] / [[Homeland Defense (BTD6)|Homeland Defense]] and [[Permanent Brew (BTD6)|Permanent Brew]] that are intended to be sacrificed to a Paragon in the late game.
