Temple Sacrifice (BTD5 generation)

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 sacrificing enough towers with enough cash value 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 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 25 sacrifice levels.

In the mobile and console games, the Temple's main attack gains +1 damage per sacrifice level it has, up to a maximum of +25 damage (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.

Missile attack

Sacrificing Bomb Shooters and/or Mortar Monkeys unlocks an attack that fires seeking missiles that deal extra damage to MOAB-Class Bloons.

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 (Flash)	Effect (mobile)
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 Freeze duration: 2s → 2.5s	Blast radius: 250 → 300
5	Arctic wind: slows to 33% speed in radius of 105 units (BTD5) or 126 units (Battles / BMC)	Arctic wind: slows to 50% speed in radius of 240 units

Dart/blade attack

Sacrificing any other tower unlocks
