Temple Sacrifice (BTD5 generation)

"Temple Sacrifice" pop-up message in the desktop releases of BTD5

Upgrading a Super Monkey into a Temple Of The Monkey God sacrifices all towers within the Temple's range. The Temple unlocks additional attacks depending on the types of towers sacrificed and gains more powerful attacks depending on the total amount of cash spent on the sacrificed towers. Regardless of difficulty, creating a maxed-out Temple requires sacrificing at least $30,000 worth of each of the following:

• Bomb Shooters and/or Mortar Monkeys (cumulative)
• Ice Monkeys
• Glue Gunners
• Monkey Apprentices
• Any combination of other towers

It costs $150,000 total to max out all five tiers for all five sacrifice categories.

Mechanics

The enhancements a Temple gains from sacrificing depends on the types of towers sacrificed and the total amount of cash spent on those towers. When sacrificed, a tower adds its total cash value (the same metric that determines its sell value) to the sacrifice value of its corresponding category, which then determines the level of benefits gained from that category. There are five different categories of sacrifices, each with five tiers of sacrifices. Creating a maxed-out Temple requires having enough cash invested across all five categories of towers in order for each category to reach level 5.

Level	Total cost of sacrificed towers
1	$1–$1,499
2	$1,500–$3,999
3	$4,000–$9,999
4	$10,000–$29,999
5	$30,000+

In Bloons Monkey City, the Super Monkey's Monkey Knowledge multiplies the value of sacrificed towers by 10% starting at rank 5, effectively reducing the amount of cash required to meet each threshold. The multiplier increases to 20% at rank 10 and 30% at rank 15.

Tier	Total cost of sacrificed towers
	Ranks 1–4	Ranks 5–9	Ranks 10–14	Rank 15
1	$1–$1,499	$1–$1,349	$1–$1,199	$1–$1,049
2	$1,500–$3,999	$1,350–$3,599	$1,200–$3,199	$1,050–$2,799
3	$4,000–$9,999	$3,600–$8,999	$3,200–$7,999	$2,800–$5,999
4	$10,000–$29,999	$9,000–$26,999	$8,000–$24,999	$7,000–$20,999
5	$30,000+	$27,000+	$24,000+	$21,000+

Sacrifice effects

Unless otherwise stated, the effects of sacrifices are the same between all games of the same system. That is, the sacrifice effects in the Flash versions of Bloons TD 5, Bloons TD Battles, and Bloons Monkey City, as well as Bloons TD 5 Deluxe, are almost identical between each game, and the sacrifice effects in the mobile versions of Bloons TD 5, Bloons TD Battles, and Bloons Monkey City, as well as the console version of Bloons TD 5, are completely identical between each game. There are slight differences in sacrifice effects between the Flash games and mobile games.

Main attack

In the mobile games and the console version of BTD5, the Temple's main attack gains +1 damage per sacrifice level it has, up to a maximum of +25 damage with all 25 sacrifice levels (29 damage in total); however, the main attack's damage does not pass through layers, so the extra damage only applies to Ceramic Bloon and MOAB-Class Bloon layers. It has unlimited pierce at all levels.

In the Flash games, the Temple's main attack gains +5 pierce per sacrifice level and +1 damage per two sacrifice levels, up to a maximum of +125 pierce (175 total) and +12 damage (15 total) with all 25 sacrifice levels.

Missile attack

Sacrificing Bomb Shooters and/or Mortar Monkeys unlocks an attack that fires golden missiles every second, which can damage all Bloon types. At higher levels, the missiles have less pierce and a smaller blast radius, but it fires multiple missiles at a time.

Due to an oversight in the mobile games and the console version of BTD5, the level 4 and level 5 versions of the attack are identical to the level 3 version.

Tier	Effect (mobile / console)	Effect (Flash)
1	Fires 1 missile at a time with 1 damage, 200 pierce, and a blast radius of 200 units
2	Damage: 1 → 2
3	Pierce: 200 → 150 Blast radius: 200 → 150 Missile count: 1 → 3
4	No effect	Now deals +18 damage to MOAB-Class
5		Missile count: 3 → 6

Ice attack

Sacrificing Ice Monkeys unlocks an attack that fires exploding ice bombs that damage and freeze Bloons in an area. At all levels, it fires every 2 seconds, has 999 pierce, deals 1 damage, and can hit all Bloon types. At level 5, the Temple gains an Arctic Wind-like effect that passively slows all non-MOAB-Class Bloons within an area.

Tier	Effect (mobile / console)	Effect (Flash)
1	Blast radius of 200 units, freezes 1 layer for 1.5 seconds
2	Blast radius: 200 → 250 Freeze duration: 1.5s → 2s
3	Freeze layers: 1 → 2
4	Blast radius: 250 → 300	Blast radius: 250 → 300 Freeze duration: 2s → 2.5s
5	Arctic wind: slows up to 40 Bloons to 50% speed in radius of 60 units	Arctic wind: slows unlimited Bloons to 33% speed in radius of 105 units (BTD5) or 126 units (Battles / BMC)

Glue attack

Sacrificing Glue Gunners unlocks an attack that fires glue globs that splash on impact. At all levels, it fires every 0.5 seconds, glues up to 150 Bloons at a time, slows non-MOAB-Class Bloons to 50% speed, soaks through all layers, and lasts for 22.86 seconds. At higher levels, it also deals damage over time.

Due to an oversight in the Flash games, the level 4 and level 5 versions of the attack are identical to the level 3 version.

Tier	Effect (mobile / console)	Effect (Flash)
1	Splash radius of 30 units
2	Now deals 1 damage every 2.29 seconds
3	Damage interval: 2.29s → 1s	Damage interval: 2.29s → 1s Splash radius: 30 → 36
4	Damage interval: 1s → 0.5s	No effect
5	Now deals the first tick of damage after 0.1s instead of 0.5s

Whirlwind attack

Sacrificing Monkey Apprentices unlocks an attack that fires whirlwinds every 1.25 seconds that blow back non-MOAB-Class Bloons. At higher levels, it also deals damage to all Bloon types.

Due to an oversight in the mobile games and the console version of BTD5, the level 5 version of the attack is identical to the level 3 version, which makes the level 4 version stronger.

Tier	Effect (mobile / console)	Effect (Flash)
1	60 pierce, no damage
2	Pierce: 60 → 90
3	Pierce: 90 → 120 Now deals 1 damage
4	Pierce: 120 → 150
5	Pierce: 150 → 90	Damage: 1 → 2

Dart/blade attack

Sacrificing any other towers unlocks an attack that fires 16 blades in a ring around the Temple every 0.8 seconds. In the Flash games, the level 1 and level 2 versions of the attack use darts instead of blades.

Due to an oversight in the mobile games and the console version of BTD5, the level 4 and level 5 versions of the attack are identical to the level 3 version.

Tier	Effect (mobile / console)	Effect (Flash)
1	2 damage, 20 pierce, 0 radius, cannot pop Lead or frozen
2	Damage: 2 → 3 Pierce: 20 → 30
3	Damage: 3 → 4 Pierce: 30 → 40	Damage: 3 → 4 Pierce: 30 → 40 Projectile radius: 0 → 4
4	No effect	Changes the spread of the blades slightly
5		Blades can now pop all Bloon types

Strategy

Maxing out sacrifices is vital for optimal freeplay setups, but mostly just for the extra damage it grants to the main attack. In the Flash games, the missile attack is the only additional attack that has any meaningful impact on the Temple's damage output, and in the mobile and console games, none of the additional attacks have much significance.
