For the BTD3-BTD5 counterpart, see Permafrost (BTD3-BTD5).
Bloons move slowly even after thawing out.
~ BTD6 description

Permafrost is the Tier 1 upgrade of Path 1 for the Ice Monkey in Bloons TD 6. Like previous versions of Permafrost, frozen bloons move 50% slower after unfreezing, but this only lasts for one layer (2 with Deep Freeze, 4 with Absolute Zero). When crosspathed with any Tier 5 upgrade, including upgrading to Super Brittle, the Permafrost applies to blimps upon damaging, but with only a 25% slowdown instead of 50%. The Permafrost can also affect White Bloons and Zebra Bloons even though it does not freeze or damage them.

It costs $85 on Easy, $100 on Medium, $110 on Hard, and $120 on Impoppable.

Strategy[]

Summary[]

Permafrost is cheap but somewhat unreliable way of slowing down bloons. As long as bloons pass by and are not hit by other towers, the Permafrost slowdown effect will last forever. This upgrade sees the most use in its effectiveness at slowing down Ceramics, especially Super Ceramics. When given to higher-tier Ice Monkeys, the Permafrost effect on MOAB-class bloons in effect clumps them up, slowing each affected blimp down permanently when hit.

Tips[]

  • Permafrost is a cheap upgrade to get to slightly boost the Ice Monkey's stalling potential. This has been utilized on harder maps for cheaply handling mid-game rushes such as Round 63.
  • Unlike Glue Gunner glue, the Permafrost effect lasts permanently but lasts for only 1 layer (more with middle path upgrades) instead of the default 3 for glues.
  • Permafrost can be added to Absolute Zero to clump up MOAB-class bloons.
  • Generally speaking, this upgrade is not very useful for Icicle Impale because blimps currently hit reduce to a halt anyway, unless no longer hit after a while.
  • The slowdown to MOAB-class bloons via any Tier 5 Ice Monkey's Permafrost effects is equal to the amount that MOAB Glue would slow down them by. The slowdown is specifically 25%.

Verion History[]

Mostly interactions when interacting with higher-level upgrades.

17.0
Buff Tier 5 upgrades now apply Permafrost effect to MOAB-class bloons, although half the slowdown will be applied.

Trivia[]

  • Buying the Permafrost upgrade adds a snowflake symbol on the monkey's head.
  • The official artwork for Permafrost depicts the Ice Monkey blowing cold air, similar to its BTD5 artworks.
