Detects Camo Bloons and all Bloons hit become brittle, take extra damage while frozen, and lose Camo properties.
~ BTD6 Description

Embrittlement is the fourth upgrade of Path 1 for the Ice Monkey. This upgrade causes bloons frozen by this Ice Monkey to take extra damage from all attacks (+1 damage to be exact) for a duration of up to 2.0s, including sharp objects. As the embrittlement effect is applied before freezing, every ice blast also deals 2 damage per attack, although embrittlement effects cannot stack on top of each other. In addition, this upgrade allows the Ice Monkey to detect camo as well as strip off camo and regrow properties from bloons that are hit by its freeze attack.

It costs $2,550 on Easy, $3,000 on Medium, $3,240 on Hard, and $3,600 on Impoppable.

Strategy[edit | edit source]

Summary[edit | edit source]

Embrittlement's main role is to weaken groups of bloons. When placed along a bend, and grouped with many towers, it can help reduce the strength of large groups of bloons, although its rather slow attack speed may cause it to occasionally miss a few bloons. The fact that bloons frozen by the Embrittlement no longer temporarily gain immunity to sharp objects, any tower can be placed nearby without negatively impacting nearby defenses. Embrittlement is also a viable option to countering Camo and/or Regrow rounds, although not the most reliable.

Tips[edit | edit source]

  • Since Version 17.0, Embrittlement grants camo detection and camo stripping to the Ice Monkey. It is the only Primary Monkey to decamo bloons, which ends up being extremely useful in many situations, such as against Round 78.
  • Additionally, since it detects camo now, it can be a useful form of camo detection. However, due to its high price it will likely be afforded much later.
  • Embrittlement is not reliable enough camo detection against Round 47, with spaced Camo Pinks, because of its relatively slow attack speed and limited range.
  • With Embrittlement, there is no downside to placing towers that shoot sharp-based projectiles, because bloons frozen by Embrittlement are not affected by the frozen immunity. In fact, adding any other tower beside the Embrittlement is beneficial, because it allows the shards to activate more often.
  • As with most Ice Monkeys, place Embrittlement along a bend to take the greatest advantage of all of its freezing effects, especially for the benefits of decamo and degrowth.

Version History (BTD6)[edit | edit source]

17.0
  • Buff.png Embrittlement range increased (20 --> 25)
  • Buff.png Embrittlement now grants the Ice Monkey to detect camo
  • Buff.png Embrittlement now also removes camo & regrow properties from anything hit
20.0
  • Change balloon.png 4xx Embrittlement description updated to mention camo & property removal*
    • Changed from "Bloons become brittle and take extra damage while frozen." to "Detects Camo Bloons and all Bloons hit become brittle, take extra damage while frozen, and lose Camo properties."
    • The description technically remains erroneous as it does not mention the removal of regrow properties despite the intention to include it in the patch notes.
21.0

Buff.png Embrittlement now (correctly) allows all projectiles to damage bloons frozen by Embrittlement

Trivia[edit | edit source]

  • This upgrade is the only upgrade of the Ice Monkey where the skin color of the monkey is not a cold color (i.e. greens, blues, purples). Instead, Embrittlement's skin color is red.
  • "Embrittlement" is an actual word used within the material science study field that describes a decreased toughness of a material, thereby a loss of ductility, in turn rendering the material to become brittle. Objects that suffer from embrittlement become easier to rupture when forced under pressure, similar to what the Ice Monkey's Embrittlement upgrade does to bloons.
  • Unlike actual embrittlement, lowering the temperature of a material only temporarily renders a material to become brittle, until the temperature returns to the original amount. This is similar to what happens with the Ice Monkey's Embrittlement upgrade, as bloons will only temporarily gain the embrittlement vulnerability including after thawing.
  • The phenomenon called embrittlement also alters the properties of a material, which makes sense for both the Embrittlement upgrade setting a +1 damage vulnerability to all affected bloons and stripping off Camo and Regrow properties.
  • The Version 17.0 buff to Embrittlement whereby it can strip camo is based upon the Tier-4 Ice Fortress upgrade, exclusive to BTD5 Mobile and BTD5 Steam.
  • This upgrade (alongside Super Brittle, its leading upgrade) is the first upgrade in BTD6 to receive a camo detection buff.
  • Despite the buffs on Version 17.0, the description for Embrittlement was not changed to accommodate the new buff functionality until Version 20.0. The description still does not mention the removal of Regrow properties, however.
  • Although Embrittlement cannot specifically target DDTs, Embrittlement is able to decamo DDTs with the ice shards. This is probably a bug.
