Sentry Champion (formerly named Sentry Paragon before Version 28.0) is the Engineer Monkey's path 1 tier 5 upgrade in Bloons TD 6. It now deploys Champion Sentries that self-destruct after expiring, causing a large explosion that pops 50 Bloons (75 with Oversize Nails) and deals 100 damage. Champion Sentries shoot plasma balls that pop up to 5 Bloons (10 with Oversize Nails), and deal 3 damage (+1 MOAB-Class and +1 Fortified damage with Deconstruction), and have 50 range (54 with Larger Service Area).

Sentry Champion excels when super-buffed, with high synergy with speed buffs and fast-attacking Champion Sentries that work well with blimp debuffs. Despite its moderate T5 standalone cost, it's one of the cheaper T5's in total cost.

Version 20.0

“

Continuing our efforts to make crosspaths meaningful and fit the style of each path more solidly, a number of crosspath and base level balance shifts were made.
— Update notes

”

•  Paragon Sentry: explosion radius now scales with range modifiers
•  Sentry: deployment rate increased ― 7s → 6s

5-1-0, 5-2-0

•  Larger Service Area crosspath now increases Sentry range by +4

5-0-1, 5-0-2

•  Oversize Nails crosspath now allows Sentries to pop frozen Bloons
•  Oversize Nails crosspath now increases Sentry pierce by 1

Version 21.0

•  Sentry explosion: Damage increased ― 85 → 100

Version 23.0

5-2-0

•  Deconstruction: now grants all Sentries +1 damage to Fortified & MOAB

Version 26.0

“

Additionally higher tier sentries will now be able to benefit from the xx2 Pin crosspath, so enjoy some laser pins.
— Update notes

”

5-0-2

•  Pin now allows Sentries from Sprockets and above to pin Bloons

Version 28.0

“

Alright, Sentry Paragon is now a Champion
— Update notes

”

• Name changed

Before	Sentry Paragon
After	Sentry Champion

Version 33.0

“

The MOAB offense of top path lacks for a mainly dps tower that is quite complex to use [...] the 320 crosspath will now be able to double dip on the Fortified & MOAB damage bonuses that it gains.
— Update notes

”

•  Nailgun: Attack cooldown reduced ― 0.42s → 0.3s (attack speed increased by 40%)

5-2-0

•  Sentry: Deconstruction's bonus damage to MOAB-Class Bloons and Fortified Bloons are no longer mutually exclusive

Version 35.0

“

Sentry Champion’s pierce crosspath does not feel like it has enough of an edge to compete with the deconstruction crosspath.
— Update notes

”

5-0-1, 5-0-2

•  Turret pierce increased ― 6 → 7

Version 39.0

“

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.
— Update notes

”

5-0-1, 5-0-2

•  Sentry Explosion: Crosspath benefit to pierce bonus increased ― +1 → +21
  • Note: Pierce increased from 51 to 70

Version 43.0

“

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. Sentry Champion, while strong with them, is lacking without high buff support so we’re trying out an increase to the sentry damage on it.
— Update notes

”

•  Overall cost reduced by $50 (due to cost changes for previous tiers)
•  Champion Sentry: Damage increased ― 2 → 3
•  Sentry deployment: Sentries now spawn within 20% of their range to the track

Version 47.0

“

This was becoming annoying screen clutter with large numbers of sentries, and feels unnecessary when you can overclock the engineer itself to create more sentries instead.
— Update notes

”

•  Overclock and Ultraboost abilities no longer target Engineer sentries

Version 48.0

“

Really only one major change here; a rebalancing to how the 2xx Crosspath applies across various engineer upgrades, and some base stats being changed to accommodate fitting this.
— Update notes

”

•  Sentry deploy: Attack cooldown reduced ― 6s → 5s

5-0-1, 5-0-2

•  Champion Sentry, Plasma: Pierce increased ― 7 → 10
•  Champion Sentry, Explosion: Pierce increased ― 70 → 75
