* '''Snowstorm Roar''': The Paragon freezes all Bloons on screen, applying [[Permafrost (BTD6)|permafrost]] to Bloons below a [[BAD (BTD6)|BAD]], removing [[Camo Bloon|Camo]] and [[Regrow Bloon (BTD6)|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 {{BTD6 dt|Cold}}, {{BTD6 dt|Frigid}}, or {{BTD6 dt|Glacier}}-type damage. This debuff overrides both [[Embrittlement (BTD6)|Embrittlement]] and [[Super Brittle (BTD6)|Super Brittle]]. BADs and [[Boss Bloon|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 ~~while~~ frozen, the skull effects are [[#Activated Ability|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.

* '''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''': It is applied 5 seconds after the ability is activated, ~~it affects~~ 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 ~~lasts~~ for 10s and slows regular Bloons by 75% and MOAB-Class Bloons by 50%, but it doesn't affect BADs or Boss Bloons~~. It is also applied 5s after the ability activation~~.

* '''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. {{BTD6 mk|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 ~~on Bosses where~~ if a skull is triggered between the moment the freeze is applied ~~(5s after ability activation)~~ and the end of the ability (when the ~~lightning~~ returns to normal), the ~~skull's~~ effect ~~will be negated~~, ~~but~~ the Boss will thaw early if it is frozen. This effect can only be used once per Boss tier. Specific interactions with Bosses are as follows:

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.

==Strategy==

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 ~~debuff~~ and an ability capable of skipping Boss skull effects and freezing even {{BTD6|BAD}}s.

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 {{BTD6|BAD}}s. Towers that work well with {{BTD6|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.

~~Towers that work well with {{BTD6|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.~~

This Paragon shines in Freeplay, complementing the [[Bloonjitsu (BTD6)|Bloonjitsu]] + [[Shinobi Tactics (BTD6)|Shinobi Tactics]] strategy. Despite its ability's long cooldown and round restriction, it along with [[Time Stop]]s are the only ways to slow BADs, and these effects stack.

Line 101:

*[[Bloonarius (BTD6)|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 {{BTD6|DDT}}s 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 (BTD6)|Vortex]]: ~~Is a~~ double-edged sword as the Boss would not be knocked back, but a detrimental tower stun can be avoided.

*[[Vortex (BTD6)|Vortex]]: A double-edged sword, as the Boss would not be knocked back, but a detrimental tower stun can be avoided.

*[[Dreadbloon (BTD6)|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 (BTD6)|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 (BTD6)|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 {{BTD6 mk|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 (BTD6)|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 [[Embrittlement (BTD6)|Embrittlement]]s, and the most expensive are 2-4-0 [[Snowstorm (BTD6)|Snowstorm]]s. Icicles is still preferred for maximum degrees if placed over many rounds. [[Silas (BTD6)|Silas]] with his bonus T5 Ice Monkey provides a headstart to its degrees, but [[Geraldo (BTD6)|Geraldo]]'s [[Paragon Power Totem]]s are still generally preferred for that purpose.
