Introduced	Version 46.0

The Crucible of Steel and Flame is the Tack Shooter's Paragon in Bloons TD 6, introduced in version 46.0. It is a combination of Inferno Ring, Super Maelstrom, and The Tack Zone.

The Crucible of Steel and Flame's basic attack is similar to the Blade Maelstrom ability, but with limited area coverage. It shoots four rotating streams of white hot blades that each split into a nova of eight tacks when they expire. It constantly fires blades even when Bloons are not within its range. It can only detect Camo Bloons when granted Camo detection by the Ascended Shadow.

It has two Activated Abilities:

• The Maelstrom ability temporarily increases its projectile lifespan, allowing both its blades and tacks to travel much further and cover a much larger area overall, and grants it a second attack that blasts jets of flame in a ring around itself, dealing damage in an area similarly to Ring of Fire and Inferno Ring. It lasts for 9 seconds and has a 20-second cooldown.
• The Meteor Impact ability targets a Bloon and strikes it with a meteor, dealing enormous damage in a large area around the target and spawning a circle of 32 high damage homing fireballs around the point of impact. It has a 60-second cooldown.

This article 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: Confirm if tacks can hit the same target as blades (look for the presence or absence of a "filter" to the parent, whether it be a property that matches Shrapnel Shot, Airburst Darts, or something like that)

Crucible of Steel and Flame's main attack is a passively attacking blade nova that is offset higher than its own centerpoint. The blade nova consists of two copies of a rotating twin blade attack 180° apart, rotating their offsets in opposite directions at 360° per second. Each blade has 2 radius and moves at 140 units per second, and lasts up to 0.25s. Once expired or hits an obstacle, each blade produces a nova of eight tacks that can hit the same target. The nova has 360° spread. Each tack has 0 radius (i.e. can only hit Bloons with its centerpoint), move at 120 units per second, and last up to 0.15s. Both blades and tacks have low pierce and damage but do extra damage to Bosses. None of its attacks can hit Camo without Camo detection from Ascended Shadow. It is affected by Fast Tack Attacks.

Its range is 42.32, which is roughly less range than its blade nova.

At Degree 1:

• The blade attack is shot every 0.0325 seconds.
• Each blade deals 20 damage, +30 Boss damage, and has 5 pierce.
• Each tack deals 10 damage, +20 Boss damage, and has 3 pierce.

Activated Abilities

Maelstrom ability

This article 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: Confirm if bonus lifespan also affects Meteor Impact when triggered while ability is active

Maelstrom ability increases lifespan of all its attacks by ×2.5, and adds a flame ring that is similar to Ring of Fire, both lasting for 9 seconds. The lifespan bonus also affects Meteor Impact when that ability is activated while Maelstrom ability is active. The flame ring has 45 radius, high pierce, and does more damage to Bosses. The flame ring cannot detect Camo Bloons without the support of Ascended Shadow. This ability has a base cooldown of 20 seconds.

At Degree 1:

• The flame ring attacks every 1 second and does 250 damage, +250 Boss damage, and has 80 pierce.

Meteor Impact ability

This article 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: Confirm delay amount of meteor initial delay between triggering and hitting target.

Meteor Impact creates a meteor that targets and pursues a Bloon based on targeting priority, producing a large explosion that produces 32 homing fireballs that can re-hit Bloons. None of its attacks detect Camo without support of Ascended Shadow. It has a base cooldown of 60 seconds.

The meteor takes about 0.5 seconds to hit its target. The explosion has 120 radius and has very high damage and pierce. The resulting fireballs have 360° spread. Each fireball moves at a rate of 40 units per second, accelerates at 2 units/s², and has a max speed of 80 units per second. While seeking, a fireball can target Bloons practically everywhere, can seek from any direction, rotates at a rate of 360°/s, and lasts up to 5 seconds. Each fireball has 2 radius and can re-hit Bloons after 0.5s.

At Degree 1:

• The meteor does 60,000 damage and has 500 pierce.
• Each fireball does 900 damage and has 2 pierce.

Strategy

This strategy section is empty or incomplete. See the strategy guidelines for more information on how to write strategy sections. The editor who added this notice elaborates: Add more strategizations of Crucible, and also state degree processes and how to do paragonning stuff like makeshift paragon and optimizing degrees. (Also, ascended camobuff isn't full uptime on paragons? people are rumoring ascended shadow full uptime on paragons) And verify use cases of when to properly time abilities (maelstrom ability debatable of in center better, might be worse?)

This section was last updated for: version 52.1

The Crucible of Steel and Flame is notable for being the second cheapest Paragon in the game, behind Apex Plasma Master. The majority of the Crucible's power stems from its abilities, most notably Meteor Impact for its powerful burst damage and AoE making it a very cost-efficient Paragon. Degrees have a great impact on the Crucible's potential DPS all around, especially with the flat pierce boosts for its homing meteors.

One of the Crucible of Steel of Flame's best matchups is Diamondback as its projectiles can all hit the head simultaneously. Furthermore, the Maelstrom ability easily deals with the Bloons it spawns each skull, including Diamond Bloons. Its worst matchup is Phayze as it lacks inherent Camo detection; even with it granted by Ascended Shadow, it loses almost all of its DPS whenever Phayze hits a skull. Additionally, the Maelstrom ability is almost useless versus Lych because the Boss steals the self-buff.

Alongside positioning, timing abilities are important. Time Maelstrom when the Boss is within the Crucible's range to make the most of its Ring of Fire's damage. Use Meteor Impact for certain Bosses when they are no longer immune to damage after reaching a skull (e.g. Vortex when its shield is down, Dreadbloon when no longer in Primary immunity, and Blastapopoulos a few seconds after creating Pyroclastic Rocks).

For maximum pops, place all of the T5 Tack Shooters near the front of the track. For cheapest T2 and T3 crosspaths for the most tiers, use 0-2-2 and 0-2-3. The cheapest T4 for the most tiers is 0-4-2 Blade Maelstrom, and for most expensive use 4-2-0 Ring of Fires. However, 2-0-4 Overdrive is preferred if transitioning into the Paragon, since this T4 has the best DPS against MOAB-Class Bloons.

Version 47.1

•  Resolved an issue where Tack Paragon’s Maelstrom ability stopped increasing lifespan (bug fix)

Version 48.0

•  No longer grants full map range to Advanced Intel Subs (bug fix)

Version 49.0

“

Tack Paragon’s abilities on the other hand are both seeing an improvement to help support their roles and highlight that strong ability use case — Update notes

”

•  Meteor Impact ability: Cooldown reduced ― 90s → 60s
•  Maelstrom ability: Pierce increased ― 60 → 80

Version 50.0

“

To match the base tacks fired by Tack Shooters the Tack Paragon’s tack nova count is increasing, which along with lower projectile lifespan should tighten up the effective single target damage close to the tower. Eruption ability’s lifespan bonus is also being increased to keep the tower’s long-range buff very similar to how it was before even with the lower starting lifespan. — Update notes

”

•  Main attack — sub-projectile: Count increased ― 6 → 8
•  Main attack — main projectile ― Lifespan reduced → 0.3s (0.25s)
•  Main attack — sub-projectile: Lifespan reduced ― 0.2s → 0.15s
•  Maelstrom ability: Projectile lifespan bonus increased ― ×2 → ×2.5
  • Note: With Maelstrom, blade lifespan increased from 84 to 87.5, tack lifespan decreased from 48 to 45.
•  Maelstrom ability: Initial cooldown is fully reset ― 6.67s → 20s (undocumented)
•  Meteor Impact ability: Initial cooldown is fully reset ― 20s → 60s (undocumented)

Version 53.0

“

We feel the Tack Paragon needs a nudge to help it compete against other paragons as this price range proves to be quite easy to skip over. — Update notes

”

•  Meteor Impact: Meteor explosion damage increase ― 50,000 → 60,000
•  Meteor Impact: Fireball damage increase ― 700 → 900
