The Master Builder is the Engineer Monkey's Paragon in Bloons TD 6, introduced in version 32.0. It is a combination of Sentry Champion, Ultraboost, and XXXL Trap. The Master Builder attacks by firing three nails at a time that can Pin any Bloon except BADs and Boss Bloons, stunning them for 5 seconds on each hit. At the end of each round, it applies an Ultraboost-like effect to itself that permanently increases its attack speed by 30%. It has an Activated Ability that deploys one of three types of Mega Sentries anywhere on the map. Each Mega Sentry has a different attack.

• The Green Sentry Paragon emits a persistent laser with infinite range. Like Plasma Accelerator, it can follow the player's cursor or be locked in place.
• The Red Sentry Paragon rapidly shoots four streams of plasma in a cone similar to a Sun Avatar.
• The Blue Sentry Paragon shoots missiles that deal heavy damage to MOAB-Class Bloons. Like the M.A.D, the missiles can pop any Bloon type and pierce through Bloons, creating explosions on each collision.

All of the Mega Sentries also spawn their own temporary Sentries called Modified Sentry Paragons every 6 seconds. Modified Sentry Paragons rapidly shoot balls of plasma and explode when they are sold or after they expire, similar to Champion Sentries. The Master Builder, Mega Sentries, and Modified Sentry Paragons can all detect Camo Bloons.

The Master Builder can have one of each Mega Sentry on the map at a time. If a Mega Sentry is sold or a second one is placed with the ability, the Mega Sentry and all of its Modified Sentry Paragons detonate simultaneously, dealing massive damage to Boss Bloons in particular. If the Master Builder is sold, all of its Mega Sentries and their Modified Sentry Paragons detonate at once.

At the end of each round, the Master Builder's attack speed permanently increases by 30%, capping at an attack speed of ~6.67 shots per second (attack cooldown of 0.15 seconds). Since the Master Builder's base attack speed scales with Degree, it takes fewer rounds for it to reach the cap at higher Degrees.

Ability

The Master Builder's Activated Ability allows the player to place a Mega Sentry sub-tower anywhere on the map. It deploys a Green Sentry Paragon on its first use, a Red Sentry Paragon on its second use, a Blue Sentry Paragon on its third use, then repeats the cycle with the Green Sentry Paragon. Its icon changes to indicate which Mega Sentry it will deploy next. If a Mega Sentry is sold or a second copy of the same Sentry is placed with the ability, it and all of its Modified Sentry Paragons will detonate instantly. If the Master Builder is sold, all of its Mega Sentries and Modified Sentry Paragons will explode. The Mega Sentries' explosions have some of the highest non-instakill damage values in the game and deal much more damage to Boss Bloons. Each Mega Sentry has a range of 70 distance units and has the same detonation and Modified Sentry Paragon spawning mechanics, but has a unique main attack. The stats of the Mega Sentries and Modified Sentry Paragons depend on the Master Builder's Degree. The ability has a base cooldown of 20 seconds.

Green Sentry Paragon

The Green Sentry Paragon fires a persistent laser beam towards the player's cursor or a specific point with the lock in place targeting that extends up to the distance between the Sentry and the target position, similar to Plasma Accelerator. The beam rapidly deals plasma damage to Bloons on contact, does extra damage to Boss Bloons, and deals extra damage at the tip. The beam's damage rate scales with Degree like a normal attack.

Red Sentry Paragon

The Red Sentry Paragon rapidly shoots four streams of plasma-type projectiles with a spread of 30°. It inherits the Master Builder's targeting.

Blue Sentry Paragon

The Blue Sentry Paragon fires missiles that pierce through Bloons, generating an explosion on each collision. Similar to Hydra Rocket Pods and above, each collision consumes two units of pierce instead of one, so the flat pierce buffs from higher Degrees are only half as effective on the missile (though the explosions' pierce scales with Degree normally). The missile itself only deals damage to MOAB-Class Bloons, despite being able to hit all Bloon types, but the explosions can damage all Bloon types. The Blue Sentry Paragon inherits the Master Builder's targeting.

Modified Sentry Paragon

Modified Sentry Paragons are temporary sub-towers spawned by Mega Sentries every 6 seconds, making them sub-towers of sub-towers. The rate that Modified Sentry Paragons are spawned at does not scale with Degree. They are very similar to Champion Sentries, rapidly shooting balls of plasma that deal bonus damage to MOAB-Class Bloons and Boss Bloons, plus creating an explosion that deals plasma damage in a large area when destroyed. If it expires on its own, it explodes after two seconds, but if it is sold, its parent Mega Sentry is destroyed, or the Master Builder is sold, it will explode immediately. Each Modified Sentry Paragon lasts for 19 seconds (24 seconds with Vigilant Sentries). Modified Sentry Paragons created by Red and Blue Sentry Paragons inherit their targeting, while ones created by Green Sentry Paragons inherit the Master Builder's targeting.

Version 21.0

“

Engineer is quite poor in terms of crosspathing, so we’ve added crosspath benefits to Cleansing Foam as well as an overall price buff to the middle crosspathing upgrades. We’ve been somewhat unhappy with how Overclock sits in the game for a while and especially how the interaction with tower cost causes levelling heroes naturally to be far advantageous over purchasing upgrades when this is already underused. We have made an attempt to rework these issues by moving it to a tier-based system rather than price.

Version 23.0

“

Sentry Expert has underperformed for a while, so we’re adding solid crosspathing buffs to all Sentries. We’ve added a pierce & speed boost to Overclock’s base upgrade and lowered the cooldown on Ultraboost to allow the possibility for it to achieve full uptime as a freeplay tower and get its stacks up faster. Finally last update we allowed Bloontrap to be set multiple times per round, and we wanted to stay on the side of caution with a long cooldown, but after seeing it in the wild we are happy to make this cooldown faster.

The MOAB offense of top path lacks for a mainly dps tower that is quite complex to use, T3 Sprockets already feels underwhelming so is seeing a buff here carrying up to T4, and the 320 crosspath will now be able to double dip on the Fortified & MOAB damage bonuses that it gains. Cleansing Foam is only seeing a slight tweak to help it be more viable if you want to attempt it as 'main camo detection’, and this mainly fixes some issues in ABR games allowing it to catch quick initial camo spawns.

XXXL Trap 205 crosspath hasn’t actually ‘been working’ due to the base attack rate being faster than minimum deployment delay so we have slowed the base rate to make 205 crosspath actually matter.

Applying pierce crosspathing to Sentry Champion only granting an abysmal +1 pierce to the explosion while an intended joke at the time still feels a little silly, we’re separating that up to get its own larger increase now.

While better than many options, base Engineer still takes a lot of available starting cash so the cost is reduced slightly and being moved back up into Cleansing Foam & Bloontrap; also with a reduction to Double Gun’s price to reflect the lower value of the base tower. Sentry placements are slightly changing to improve their reliability, and will now spawn closer to the track depending on how much range the sentry has.

The Ultraboost ability is now starting on cooldown to put a limit on buy’n’resell issues, but this is to ease up on the use per round limit which was causing frustration.

“

Now that Ultraboost has an initial cooldown we are again allowing it to be used between rounds. Middle crosspath feels too good for Bloontraps because of the massive quality of life it brings, so we’re pushing the DPS more for top crosspath by allowing Double Gun to also double the projectiles of Sentries. The expensive XXL Trap's cash generation comes in too late given Bloontraps fall off as an income generator in the late game, so we’re reducing the upgrade cost and increasing the cash generation that it brings.

Tiers	Changes
Paragon Master Builder	Power Glove ability: effects now persist between saves  Sub Towers from Paragons should now correctly be stunned when the main tower is

Version 50.0

“

Overclock’s Village range bonus always felt like an odd special case, and now that there is a proper dedicated range bonus ability the combined range this grants for villages ended up being overpowered, after consideration we didn’t want to jump straight to deleting the ultraboost stacking tech here but have lowered the range bonuses from Overclock.

Engineer Paragon is no longer balanced due to its new ability, so we’re adjusting its base attack rate and range to bring it a little more back in line

Tiers	Changes
Paragon Master Builder	Main attack: Attack cooldown increased ― 1s → 1.5s (attack speed reduced by 33.33%)  Range decreased ― 70 → 60 Note: Mega Sentries and Modified Paragon Sentries unchanged (70 and 50)

Version 52.0

“

Engi Paragon is too good across the board since the addition of its Overclock ability, we’re moving the Village Range buff in line with the normal overclock, and nerfing its ability cooldown so that higher degrees are required to keep a high uptime buffing other paragons. Since the AoE overclock is unique to the Engineer Paragon and not aimed at other Paragons that part of the ability is instead being improved on.

• Engineer Paragon’s changes has some issues, so clearing this up for now
  • Duration is set to 60s
  • Tiers 1-5 receive a duration multiplier of 1x
  • Paragons receive a duration multiplier of 0.25x
  • The AoE duration will now also last 60s instead of 30s, not intended but we will be leaving this in as is for now

Version 53.0

“

Engineer Paragon's power glove pairs up much too well with some paragons compared to others so we’re trying out a shift to lower cooldown but also lower duration to break this up.

Version 54.0

“

[While talking about Wizard Paragon changes] Since its addition this synergy has been a problem for Paragon balance, so we’re implementing a special-case to make Overclock less effective on the Wizard Paragon; this allows us to buff that lost power back into the Powerglove Overclock. Since these changes are "magically" linked, we’re mentioning the Engineer buff here too—also to cast Confusion on anyone who skips this section and only reads the Engineer notes!

[...]

Overclock’s duration on level 20 heroes has been excessive; we’re cutting the jank and standardizing to a consistent 30s duration for heroes, with Ultraboost still providing the full 60s.

“

Oh yea we have one more tower balance change. As the Engineer paragon moves to a more supportive role, we are toning down the direct boss damage and attack speed but also lowering the upgrade cost.
