Activated Ability

Icons of many Activated Abilities on Bloons TD 6, abilities that are not currently available are shown in a darker color and with an orange circle that indicates remaining cooldown.

Activated Abilities are a game mechanic introduced in Bloons TD 5. These are special attacks or powerful effects that certain towers can perform after obtaining a certain upgrade and must be activated manually. After being used, the abilities go into a period of time where they cannot be used again known as ability cooldown (to differentiate it from attack cooldown), and once this time expires, the ability can be used again.

Mechanics

In most Bloons TD games where they appear, Activated Abilities share a common set of mechanics with very few exceptions, for particulars on a specific game check their corresponding section below.

• All tower types have at least one Activated Ability, but is usually restricted to a specific upgrade, for example in games from the BTD5 generation, they are obtained from a path 2, tier 4 upgrade, meanwhile Heroes in the BTD6 generation gain an ability at Levels 3 and 10.
• After purchasing the upgrade, the game will show an icon on the screen with an image corresponding to the ability, and to activate it, the player must click on the icon.
• If the player has multiples of a tower which has an ability, each individual tower will be able to perform it independently from the rest, and the icon on the screen will show a number indicating the amount of uses that the player has available across all towers on the map.
• After using an ability, the tower it belonged to will start a timer where it cannot be used again, this is known as an ability cooldown and its duration might be different for each individual ability. In the user interface, the icon will change slightly to indicate that it is not available and present some sort of graphic to indicate the remaining time until it is recharged.
• When the upgrade is purchased, the ability may be instantly available or start in cooldown for game balance reasons, also they may or may not be used in breaks between rounds.
• Certain towers or game mechanics can provide buffs to decrease the amount of time needed to recharge an ability, but these are independent from the usual attack speed buffs.

Bloons TD 4

Although abilities were not formally introduced until the next main entry of the series, a precursor of this mechanic is found by upgrading a Monkey Beacon into a Monkey Storm Beacon, which allows it to call a Super Monkey Storm on command by paying some cash.

Bloons TD 5

Activated Abilities were formally introduced in BTD5, and are obtained by upgrading towers to their path 2 tier 4 upgrade, with the exception of the Banana Farm. Certain Special Agents can also have an ability.

Bloons TD 6

Upgrade screen of the Dart Monkey in BTD6, upgrades that concede Activated Abilities are highlighted by a orange thunder symbol in the top right of the upgrade icon. In this case it only applies to the middle path on tiers 4 and 5.

In Bloons TD 6, activated abilities are usually obtained by upgrading towers into their middle path, usually on tiers 4 and 5, but some tier 3 upgrades can also have abilities. Heroes on the other hand gain their abilities when they reach Level 3 and Level 10, but some of them also have a third ability at Level 7.

For balance reasons, specially in competitive modes, some abilities may have restrictions on how often they can be used:

• Have a limited amount of activations per round, this is specially evident on Cash-generating abilities.
• Can only be activated in 3 minutes from the round start.
• Needs to pay lives as a cost.
• Cannot be used during the break between rounds.
• Disabled during the penalty timer of Boss Bloon Events and Contested Territory Boss tiles.

Buffs that reduce the ability cooldowns stack additively, including the penalty from Blastapopoulos's passive abilities, but the cooldown can only be decreased by up to 70% from its normal amount (excluding challenge modifiers).
