The Herald of Everfrost is the Ice Monkey's Paragon in Bloons TD 6, introduced in version 52.0. It is a combination of Super Brittle, Absolute Zero, and Icicle Impale.

The Herald of Everfrost's attacks alternate between four Ice Lance Beams and one Snowstorm Roar; either attack is only used when Bloons are in range. It also has an Arctic Wind-like aura that greatly slows Bloons and MOAB-Class Bloons within its radius. The Paragon creates ice platforms for the water placement of land towers globally.

• Ice Lance Beam: The Paragon launches an ice beam attack with very high pierce which travels in a straight line and freezes all damaged Bloons for 10 seconds, leaving a trail of groups of 6 giant ice shards as it travels. Bloons that survive the attack grow icicles that damage other Bloons.
• Snowstorm Roar: The Paragon freezes all Bloons on screen, applying permafrost to Bloons below a BAD, removing Camo and Regrow properties, removing Lead and Frozen immunities, and inflicting a debuff that causes Bloons to take +8 damage from all attacks with an additional +40 damage from attacks that deal Cold, Frigid, or Glacier-type damage. This debuff overrides both Embrittlement and Super Brittle. BADs and Boss Bloons also receive the damage debuff with the visual effect, but they are not slowed.

Additionally, it has an Activated Ability called Eclipse of Fimbulwinter. It has a 5-second delay before freezing every Bloon on screen for 10 seconds, although BADs and Bosses are only frozen for 5 seconds. If a Boss Bloon reaches a skull after getting frozen during the ability, the skull effects are skipped completely, and the Boss thaws early. It has a cooldown of 90 seconds and can only be used once per round. It can be used multiple times per Boss tier, but can only cancel the effects of one skull per Boss tier.

The Monkey Knowledge Icy Chill improves its range by 3 units.

Herald of Everfrost has a single attack that alternates between four Ice Lance Beams and one Snowstorm Roar. Its base range is 46 units (49 with Icy Chill) and has an attack cooldown of 4s at Degree 1.

Ice Lance Beam

This attack is composed of two parts. First, the Ice Beam itself which is a short-lived blue-colored beam similar to Ray of Doom which travels instantly to the edge of the map ignoring blockers, it has a radius of 2 units and Bloons that are hit by it are frozen and grow icicles:

• Freeze: It can freeze all Bloons, except BADs and Bosses, the effect lasts for 10s and affects up to 6 layers. It also and reduces Heat of Blastapopoulos by 600. It also deals additional damage, with the freeze applied before the damage.
• Icicles: The Icicles damage other Bloons that touch them (except other Bloons affected by this effect). It lasts for 1.5s and each affected Bloon can re-hit the same target if it is still touching it after 0.2s.

Second, the Ice Shards, which are a series of projectile bursts created by a secondary invisible "beam" that is launched in the same direction as the main Ice Beam, it travels at a speed of 150 units/s with a lifespan of 4s. Bursts of shards are periodically created as it travels through the air and each one occurs with a delay of 0.5s after the invisible projectile has passed over and it creates 6 shards in a circular pattern (shifted 45°). Each shard has a radius of 5 units, and travels in a straight line with an initial speed of 350 units/s but they decelerate until disappearing after traveling ~41 units. The shard spawn cooldown is affected by degrees and attack speed buffs such as Master Builder's Power Glove. Each shard also reduces Heat of Blastapopoulos by 60.

At Degree 1:

• The Ice Beam deals 600 Normal damage with an additional +6,000 against bosses and has 500 pierce.
• The freeze effect deals an additional 600 Normal damage, even if the target cannot be frozen.
• The Icicles deal 10 Normal damage with an additional +40 for blue MOABs and +300 for Boss Bloons. They have infinite pierce.
• Bursts of shards are created every 0.2s.
• Each Ice Shard deals 25 Normal damage with an additional +50 for blue MOABs and +125 for Boss Bloons and has 25 pierce.

None of the attacks of projectiles are affected by Big Cryo Blast.

Snowstorm Roar

Snowstorm Roar is a map-wide effect (still needs a target in range to use the attack in the first place) with infinite pierce that damages and applies several effects to all Bloons. Effects include:

• Freezes all Bloons, except BADs and bosses, for 10s and lasts for 8 layers. It is applied after the damage and the duration for MOAB-Class Bloons is halved (5s).
• Applies a Permafrost effect with infinite duration for the top 6 layers. The speed of MOAB-Class Bloons, except BADs and Bosses is reduced by 25%, and 50% for all other Bloons.
• Applies an Embrittlement-like effect that debuffs all Bloons for 10s (all layers are affected), including BADs and Bosses, and causes them to take +8 damage from all attacks and +40 additional damage (total of +48) from attacks that deal Cold, Frigid, or Glacier-type damage. BADs and Bosses receive a visual effect to indicate that they are debuffed. It also overrides the debuffs from Embrittlement and Super Brittle.
• Removes Camo and Regrow properties.
• Removes Lead and Frozen immunities from all Bloons, with infinite duration.

At Degree 1:

• It deals 10 Normal damage, with an additional +200 damage to already frozen Bloons.

This attack reduces the Heat of Blastapopoulos by 6,000 and Hypothermia does not increase the duration of any of the effects.

Arctic Wind

This section is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: Determine if its radius is affected by the Icy Chill MK

Herald of Everfrost has an aura that slows regular Bloons by 90% and MOAB-Class Bloons by 45% within 46 units. It does not affect BADs or Boss Bloons.

Global ice platforms

This section needs more screenshots. See the screenshot guidelines for more information on what screenshots are needed and how to add them. The editor that added this notice elaborates: Ice platforms of Monkeys on screen far away from the Herald

After upgrading to Herald of Everfrost, all water on the entire map gains special ice platforms. The ice platforms themselves are functionally equivalent to normal ice platforms from Arctic Wind or Silas. Visually, the Herald of Everfrost's platforms are dark blue ice platforms. When Herald of Everfrost is sold, all land monkeys on the water will be sold as well, unless they are being supported by other ice platforms.

Activated Ability

This section is in need of research. You can help out by editing this article or discussing your findings on the talk page. The editor who added this notice elaborates: Does the Boss permafrost/freeze slowdown trigger every time the ability is used on the same Boss tier or only once like the skull skip?

Herald of Everfrost's activated ability, Eclipse of Fimbulwinter, causes the Herald of Everfrost to create a visual effect that darkens the entire map for 25 seconds and apply three effects to all Bloons on the map:

• Global slow effect: Lasts for 25 seconds, starting at the moment the ability is activated. It slows Boss Bloons by 5%, BADs by 10%, and all other Bloons by 30%.
• Freeze: This attack is applied 5 seconds after the ability is activated, affecting all layers and lasts for 10s. BADs and Boss Bloons are also frozen, but the duration is halved (5s). Frozen BADs move at 2.25 units/s and Bosses move at half speed.
• Permafrost: It is applied at the same time as the freeze, lasting for 10s and slows regular Bloons by 75% and MOAB-Class Bloons by 50%, but it doesn't affect BADs or Boss Bloons.

The ability has a cooldown of 90 seconds and can only be used once per round. Hypothermia does not affect duration of the ability. Additionally, Blastapopoulos heat bar is reduced by 10,000,000, effectively resetting it to zero.

Eclipse of Fimbulwinter has a special effect that causes a Boss Bloon's skull effect to be negated if the skull was triggered between the moment the freeze is applied and the end of the ability (when the lighting returns to normal), which can be triggered within 20 seconds. Once the effect is triggered, the Boss will thaw early if it was frozen. This effect can only be used once per Boss tier. Specific interactions with Bosses are as follows:

• Bloonarius: Does not spawn or scatter any Bloons.
• Lych: Lych-soul and chained MOABs do not appear, and Lych does not enter an immunity phase.
• Vortex: It does not create a shield or stun towers, but does not get knocked backwards on the track.
• Dreadbloon: It stays in its current immunity, skips the ceramic shield, and stops the spawn of Dreadrock Bloons. Any of its skulls can be skipped, even under Primary immunity.
• Phayze: Prevents the warp, keeping the Bloon spawn portal in its current position, if present, and also prevents it from setting up its Reality Shield.
• Blastapopoulos: Does not spawn fireballs or pyroclastic rocks, and its heat meter does not gain 25%.

Strategy

This section was last updated for: version 53.2

The Herald of Everfrost is a cheap but very effective supporting Paragon for Boss Events and Freeplay. Instead of DPS, its value comes from its massive bonus damage via Bloon debuffs and an ability capable of skipping Boss skull effects and freezing even BADs. Towers that work well with Super Brittle perform even better with it. The Cold bonus is not too impactful, though it has a strong synergy with Popseidon especially with its ability.

Time the Eclipse of Fimbulwinter carefully versus BADs and Bosses, as it is limited by its long delay and cooldown. Since the ability cannot carry over rounds, it must be timed during a round within its delay.

This Paragon shines in Freeplay, complementing the Bloonjitsu + Shinobi Tactics strategy. Despite its ability's long cooldown and round restriction, it along with Time Stops are the only ways to slow BADs, and these effects stack.

The Herald of Everfrost and its ability have varied matchups against each Boss:

• Bloonarius: Least effective matchup, since most Paragons already deal enough damage to deal with its minions by the late game. However, the ability's slowdown is effective against BAD spawns and limiting the Boss's progression on shorter maps.
• Lych: Particularly on rounds with DDTs and Fortified DDTs, preventing a skull will avoid Lych-Soul and Resurrected Blimps. Additionally, not being able to become invulnerable allows better chaining of high-damage Paragon abilities, such as Goliath Doomship's Carpet Bomb.
• Vortex: A double-edged sword, as the Boss would not be knocked back, but a detrimental tower stun can be avoided.
• Dreadbloon: Its best matchup against all except Primary immunity, potentially skipping the Support category completely and offering a significant Bloon damage debuff that makes unshielded Dreadbloon easier to handle by projectile spam strategies. Time just before the second (Military → Magic) or third (Magic → Support) skulls for the best results.
• Phayze: Good matchup, since it can prevent a warp. Despite stripping Camo properties, Phayze will be immune to decamo for half the time, and can still be an anti-synergy with Ascended Shadow.
• Blastapopoulos: Another very strong matchup, with the Bloon damage debuff and Heat Bar reductions assisting projectile spam strategies significantly. Skipping a skull effect is beneficial to limit Pyroclastic Rocks or Meteors where towers are close to the Boss.

If the Paragon is mainly used for the damage debuff, getting a high degree is important to maximize the uptime, but it cannot reach full uptime without an external attack speed buff (for example, it requires Degree 90 with Paragon of Power) and they do benefit reducing the long cooldown of the Fimbulwinter ability, as well as cooling Blastapopoulos faster. The direct damage increases are not too significant, but can help to an extent. Otherwise, if the Paragon is mainly used for skull skip, then Degree 1 is enough if the player buys it several rounds in advance. To maximize degrees from pops, the majority of them should come from a mixture of all Tier 5 Ice Monkeys and Icicles spam. The cheapest T2 and T3 crosspaths for the most tiers are 2-0-2 and 3-0-2, the cheapest Tier 4 for the most tiers are 4-0-2 Embrittlements, and the most expensive are 2-4-0 Snowstorms. Icicles is still preferred for maximum degrees if placed over many rounds. Silas with his bonus T5 Ice Monkey provides a headstart to its degrees, but Geraldo's Paragon Power Totems are still generally preferred for that purpose.

Version 53.0

“

Ice Monkey’s paragon has caused a big stir with the powerful mechanics it brings to the table; uptime of its passive debuffs is being lowered as currently it maxes uptime too easily without degree investment and Embrittlement debuffs will no longer be stackable - only the highest tier Embrittlement debuff will take priority. Finally players responded with a lot of love for what Ice Paragon brings but also big annoyances with timing; for QoL we have changed the skull freeze from a debuff that has to be applied to a boss to be a simple active duration, this means is instead timing 1 exact frame for the debuff to be applied the effect will just be active for a duration and should work so long as a boss skull is triggered any time within that active duration.

Trivia

• It can receive the most buffs of any Paragon, with 6: Paragon of Power, Glaive Dominus' Primary buff, Nautic Siege Core's cooldown reduction buff, Navarch of the Seas' water monkey buff, Ascended Shadow's Camo detection buff, and Master Builder's Power Glove.
• When sold while its ability is active, the dark shader applied on the screen disappears, but the ice crystal vignette effect remains.
• Until version 53.0 removed Herald of Everfrost's Shatter interaction with the Cold bonus, the Deep Heat Relic, as well as the Monkey Knowledge Hard Tacks and Hot Magic, was also able to trigger pseudo-Shatter for Sharp attacks.
