Deep Freeze is the Ice Monkey's path 2 tier 2 upgrade in Bloons TD 6. It increases the pierce of the Ice Monkey's ice attack from 40 to 45, increases the number of layers it freezes by 1, and increases its freeze duration from 1.75 seconds to 2.2 seconds.

Crosspath effects allow status effects to also carry over extra layers and last longer. These include:

• Permafrost's slowdown, increasing to 3 layers and duration to 2.2s.
• Ice Shards's "ice shards" status effect, increasing to 3 layers and duration to 2.2s.
• Embrittlement's debuffs to affect up to 3 layers, but not the debuff duration (still 2 seconds).
• Super Brittle's debuffs to affect up to 6 layers, but not the debuff duration (still 3 seconds).
• Icicles's "icicle" duration to 2.2s.

Strategy

Deep Freeze is only recommended as a crosspath, as its small pierce bonus, extra freeze layer, and extra freeze duration do not significantly improve on the capabilities of Enhanced Freeze. For crosspathing purposes, it is recommended for Ice Shards, since it does greatly improve the total numbers of shards, for Cryo Cannon and Icicles when innate Camo detection is not needed for them, and for Icicle Impale when both external Camo and Acidic Mixture Dip can be obtained. Embrittlement and Super Brittle do not benefit significantly from Deep Freeze, besides allowing self-sharding in the absence of external speed buffs, thus only crosspathing to Enhanced Freeze is generally adequate for them.

Version 2.0

•  Pierce increased ― 30 → 40

Version 8.0

•  Can now pop Lead Bloons when buffed by Acidic Mixture Dip (bug fix)

Version 34.0

“

Ice Monkey base pierce is too high, very easily countering large numbers of strong Bloons early, mid or late in the game for small investment, leading to very low tiers of ice monkey (below t3) being highly effective spam options over upgrading your ice. We are reworking some of this base pierce to require crosspath investment [...]
— Update notes

”

•  Upgrade cost increased ― $350 → $450
•  Now increases pierce by 10
  •  Overall pierce is unchanged (due to changes to previous tiers)

Version 37.0

“

Lowest tiers of ice monkey are far too effective for their cost against ceramics, with this scaling well all the way to round 100, we feel like ice duration against ceramics needs to be reduced to counter this but for now this reduction will only apply until T3.
— Update notes

”

•  Freeze duration for Ceramics is now reduced by 50%

Version 39.0

“

We’re happier with more recent freeze changes succeeding in some of the intentions of older nerfs, given the base tower value in races being hit far more than intended we’re going back over the pierce for Ice Monkey base & middle crosspath.
— Update notes

”

•  Pierce increased ― 40 → 45

Version 49.0

“

Ice Monkey value is limited at low levels where quick & spaced Bloons are the main trouble, so the cost for many low tier upgrades is moving up to higher tiers instead.
— Update notes

”

•  Upgrade cost reduced ― $450 → $300
  •  Overall cost reduced by $275 (due to cost changes for previous tiers)
•  Can now be placed on water

Version 52.2

0-2-4

•  No longer fails to damage the round 40 MOAB in Easy mode (bug fix)
