Difficulty modifiers

Difficulty modifiers are properties of maps that buff Bloons on them. Each map has different difficulty modifiers for each level of difficulty. In Collection Events, challenge maps have their difficulty modifiers replaced with modifiers from other maps, including any unique properties of those maps' modifiers (such as Crown Capers and Chamber Of The Frozen Blades' unique Camo modifiers).

Unless otherwise noted, all chance-based modifiers use these probabilities depending on the round:

• 5–14: 10%
• 15–29: 30%
• 30–44: 40%
• 45–60: 50%
• 61+: 75%

All Bloons within each round have the same chance of being modified, except on Apple Forest, Ice King's Throne Room, Flame Kitchen, Behind the Scenes, and Showtime, where only one Bloon group each round can be modified. The group is the first Bloon group according to the round's internal ordering of groups, which is not always the first group that spawns.

Icon	Description	Effect
	More camo bloons.	Non-MOAB-Class Bloons have a chance to be granted the Camo property. On Hard Crown Capers and Hard Chamber Of The Frozen Blades, the probabilities are slightly different: 6–15: 10% 15–30: 20% 31–45: 30%
	Some bloons are 1 layer stronger.	Bloons have a chance to have one extra layer. Does not affect Ceramic Bloons or MOAB-Class Bloons.
	More regrow bloons.	Non-MOAB-Class Bloons have a chance to be granted the Regrow property.
	Regrow bloons grow back faster.	Regrow Bloons regenerate layers twice as fast, except on the following map and difficulty combinations: Hard Candy Fountain: ×1.5 Extreme Bridge And Tower, Hard Desert Of Wonder, and Extreme Desert Of Wonder: 6–15: ×0.1 16–30: ×0.3 31–45: ×0.4 46–60: ×0.5 61+: ×0.7 For Bridge And Tower and Desert Of Wonder, this means the regeneration rate is reduced instead of increased, and it depends on the round. These maps do not display the icon.
	More bloons are fortified.	Lead, Ceramic, and MOAB-Class Bloons have a chance to gain the Fortified property.
	Some bloons have shields.	Non-MOAB-Class Bloons have a chance to gain the Shield property.
	Bloons move <amount>x faster.	Increases the speed of all Bloons within the round by the amount shown in the in-game tooltip. Tree Trunks' House, Apple Forest, Snow Plains, Ice King's Throne Room, and Sinking reduce the speed instead, which is not shown in-game.
	Contains zombie bloons.	Non-MOAB-Class Bloons have a chance to gain the Zombie property depending on the round: 6–15: 10% 15–30: 20% 31–45: 25% 46+: 30%
	Contains ghost bloons.	Non-MOAB-Class Bloons have a chance to gain the Ghost property depending on the round: 6–15: 5% 15–30: 10% 31–45: 15% 46–60: 25% 61+: 45% On Extreme and Impoppable on Forest Home, Floating, Parking Lot, and Lumpy House, MOAB-Class Bloons also have a chance to gain the Ghost property depending on the round: 42–45: 1% 46–60: 5% 61+: 10%
